Definitions
- Sinkers for use in knitting devices or in knitting machines have been known for many decades.
- knitting devices usually have a large number of needles, at least one needle carrier—usually a knitting cylinder—and at least one sinker carrier.
- the sinkers for use in knitting machines have stitch-forming means that are connected to the yarn during knitting.
- a knock-over edge and a hold-down edge are examples of such knitting means.
- the sinkers in knitting machines usually fulfill two main tasks: on the one hand, they serve to shape the stitch length with their knock-over edge when the needles move to their lowest (retracted) position - the knock-over position - and on the other hand they hold the knitted fabric produced with their hold-down edge down as the needles move to their highest (extended) position - the hold down position.
- each sinker performs a sinker movement in its longitudinal direction, which is coordinated with the needle movements.
- the needle movements run in the longitudinal direction of the needle, which is usually perpendicular to the longitudinal direction of the sinker.
- the direction of the needle movements can also enclose an angle with the longitudinal direction of the sinker that is smaller or larger than 90 degrees.
- the circuit boards are usually accommodated in grooves which are arranged on the upper side of the needle carrier and the top side of the circuit board carrier and run in the longitudinal direction of the circuit board. Those grooves are usually spaced apart from each other in the board width direction by groove walls.
- An example of such a device is a material removal ring, the height of which can be adjusted in order to change the direction in which the fabric is drawn off.
- a material removal ring the height of which can be adjusted in order to change the direction in which the fabric is drawn off.
- DE10015730A1 shows a sinker and a knitting machine that works according to the relative technology.
- the sinker has a hold-down edge for holding down stitches and is guided on a carrier of a knitting device. It is obvious to a person skilled in the art that the ejection movement of the knitting needles runs exactly in the opposite direction to their withdrawal movement. It is therefore also obvious that previously formed stitches are held down on the hold-down edge of the sinker during the ejection of the knitting needles and that a stitch-forming force acts on the hold-down edge, which is perpendicular to the hold-down edge - in the present case the effective direction of the stitch-forming force corresponds to the direction of the ejection movement.
- the sinker has a spring which, through cooperation with the carrier, exerts a force on the sinker which acts perpendicularly to the ejection movement of the knitting needles.
- the force exerted on the circuit board is intended to compensate for manufacturing tolerances and to ensure that the circuit board rests securely on the carrier when the circuit board is moved from its locked position into its knock-off position.
- Such a sinker can be deflected in the knitting process in the effective direction of the stitch-forming force and thus make unwanted movements that lead to sinker strips in the generated.
- DE2154323A1 shows a device for stitch formation on circular knitting machines with a sinker and a circular knitting cylinder.
- the sinker has a lower leg (#13) which is guided in a ring guide (#12) so that the sinker does not move in a direction perpendicular to the sinker movement from the circular knitting cylinder or a the sinker carrier connected to the circular knitting cylinder can "lift off".
- a sinker with such a leg adapted to engage in ring guides is also known, for example from GB349443. With such sinkers, however, it has been shown that sinker strips often appear in the knitted fabric produced, particularly as the operating time increases.
- EP1057914B1 shows a circular knitting machine which is intended to restrict the sinker movement in the sinker height direction by a restricting element.
- the restricting element is arranged in a receiving portion of the knitting cylinder in such a way that it is immovable in the sinker height direction.
- the sinkers can move relative to the restricting member and the knitting cylinder in the horizontal direction, with the restricting member being positively engaged with the sinkers in the sinker height direction and sliding contact between the restricting member and the sinkers.
- the movement of the sinkers in the vertical direction of the sinkers is to be restricted by the form-fitting engagement.
- unevenness in the knitted fabric still occurs in a sinker or a knitting system with the aforementioned features. These irregularities even increase with the age of the knitting system.
- a sinker for use in a knitting machine comprises a shaft which extends predominantly in a sinker longitudinal direction, the shaft having at least one loop-forming means at its front end in its sinker longitudinal direction , which is in contact with the yarn during knitting and which takes part in the stitch formation, wherein the at least one stitch-forming means is a hold-down edge for holding down the just finished knitted fabric.
- a stitch that is connected to a knitting needle is prevented by the hold-down edge from also making a movement in the longitudinal direction of the needle during the ejection movement of the knitting needle in the longitudinal direction of the needle. Instead, it is held at the hold-down edge in a fixed position in the longitudinal direction of the needle - the stitch is held down.
- the shaft of the knitting needle slides along the stitch and the stitch "slips" onto the shaft of the knitting needle.
- stitch-forming forces act on the hold-down edge of the sinker, which act upwards in the vertical direction of the sinker.
- the shank has at least one basic sliding surface, this basic sliding surface running in the longitudinal direction of the sinker and in the direction of the width of the shank, which runs transversely to the longitudinal direction of the sinker, and the extension of the shank is limited downwards in its vertical direction of the sinker, which runs transversely to the direction of the length and width of the sinker, and is such that the Board can slide on her in the knitting operation.
- the basic sliding surface limits the extension of the shank at least in a section of the shank that extends in the longitudinal direction in its vertical direction of the sinker, which runs transversely to the direction of the length and width of the sinker.
- the sinker comprises a first partial element of a pair of effects for exerting a force that acts in the direction of the sinker height, the pair of effects preferably comprising at least one spring element and wherein the sinker can be prestressed in the direction of the sinker height with the force that can be exerted in a knitting device in order to reduce the stitch-forming forces to balance.
- the force that can be exerted acts downwards on the board in the direction of the board height.
- the force that can be exerted by the acting couple can also have directional components in the longitudinal direction of the sinker and/or the direction of the width of the sinker.
- the magnitude of the force component in the direction of the height of the board is preferably greater than the force component in the direction of the length and width of the board.
- the sinker in a knitting device can be prestressed in the vertical direction of the sinker with the force that can be exerted by the working couple.
- the working couple advantageously includes a second sub-element with which the first sub-element functionally interacts—for example by contact—to exert the force.
- this second partial element can advantageously be part of a needle carrier, a comb ring, a sinker carrier—for example a sinker ring—or a sinker lock, or this second partial element can be attached to the sinker carrier, sinker ring or sinker lock.
- the sinker usually engages a sinker cam with a drive foot and is driven by this sinker cam to perform a knitting movement that is customary for sinkers, in which the sinker moves alternately along the sinker longitudinal direction.
- this also means that part of the plate lock engages in the plate. Knitting devices are also known in which the sinker lock engages in the sinker between the drive foot and a drive-out area of the sinker.
- the drive foot can then only be in contact with the sinker cam with one of its surfaces pointing in the longitudinal direction of the sinker. This is also to be understood in the sense of this patent application as an intervention of the drive foot in the plate lock.
- the first partial element of the working pair which is part of the circuit board, is also moved here.
- the working couple can advantageously interact with each other in different ways depending on the position of the sinker in their knitting movement: for example, the force that can be exerted by the working couple can also alternately increase and/or decrease with the alternating knitting movement.
- the present invention also benefits from the fact that play, which inevitably occurs in knitting devices of the prior art after a long period of operation and which unevenness or sinker stripes in the knitted fabric produced, can be compensated for or eliminated with the measures according to the invention.
- play which inevitably occurs in knitting devices of the prior art after a long period of operation and which unevenness or sinker stripes in the knitted fabric produced.
- wear and tear will inevitably result in play in the area of the sliding contacts over the course of the service life. This play can lead to irregularities or sinker stripes in the knitwear produced.
- the force which can be exerted by the active couple also increases with increasing expulsion of the board in the longitudinal direction of the board (ie in the direction of the needle carrier).
- the exertable force in the phase Maximum knitting movement in which the sinker is driven furthest in the longitudinal direction of the sinker towards its front end (i.e. towards the needle carrier).
- this is the phase in which the knitting needle in a conventional knitting device performs a knitting movement directed in the longitudinal direction of its needle forwards in the direction of its stitch-forming means and the stitch slides out of the hook of the knitting needle over the jaw and the latch of the knitting needle onto the needle shaft . The stitch is thus held down and the sinker is in its hold-down position.
- At least one of the sub-elements can advantageously be a spring element that is elastically deformable in the vertical direction of the board (for example by bending) and can thereby provide the exertable force of the active couple in the form of a spring force in the vertical direction of the board.
- a spring element is elastically deformed to different extents during the knitting movement, depending on the position of the sinker during its knitting movement, in order to change the amount of force that can be exerted during the knitting movement. Further advantages result if the spring element is in contact with a second sub-element over a maximum of 50% of its length during knitting. Both the first partial element and the second partial element can be a spring element.
- one of the partial elements is a contact surface that is essentially rigid—that is, not resilient—and interacts with the spring element.
- the spring element can be supported on the contact surface.
- a contact surface can be, for example, a partial surface of a ring guide, a partial surface of a needle carrier, a partial surface of a cam part, or a partial surface of a circuit board carrier.
- the contact surface is arranged in such a way that the spring element is pressed against the contact surface during the knitting movement of the sinker in the longitudinal direction of the sinker and is forced to elastically deform in the vertical direction of the sinker. The driving force required for this in the direction of the knitting movement of the sinker is exerted on the sinker via the sinker lock.
- the first sub-element is a spring element of a circuit board and the second sub-element is a contact surface of a knitting device.
- the first sub-element is a contact surface of a sinker and the second sub-element is a spring element that is assigned to the knitting device.
- both the first sub-element and the second sub-element are spring elements.
- the first sub-element and/or the second sub-element of the pair of effects acts (selectively) on only one board.
- the first partial element or the second partial element can also be designed in such a way that it is functionally connected to a large number of sinkers of the knitting device at the same time.
- the working couple exerts the force preferably permanently, at least during one phase of the knitting movement, with the magnitude of the force being able to change.
- the working couple can also exert a force on the sinker when the sinker shaft is ideally aligned in the direction of the knitting movement.
- normal sinkers can cause sinker movements in which the sinker briefly supports itself in the sinker height direction with its drive foot and/or a portion of the shaft located between its drive foot and a drive-out region. A force acts briefly between the drive foot and the sinker lock in the direction of the sinker height.
- the combination of a drive foot or this section of the shaft of a sinker with a sinker lock is not an effective couple within the meaning of this patent application, because these combinations only exert a force in the sinker height direction in the event of an unwanted vertical sinker movement in the sinker height direction and thus sinker strips are formed in the knitted fabric produced cannot prevent.
- the first sub-element of the pair of effects is not a stitch-forming area of the sinker—that is, not an area of the sinker that is in contact with the yarn during stitch formation.
- the first partial element of the pair of effects is a feature that the sinker has in addition to the usual stitch-forming areas of a sinker in order to interact with the second partial element of the pair of effects to exert a force on the sinker that counteracts the stitch-forming forces that occur in the stitch-forming areas of the sinker can.
- the effect couple can, for example, comprise a magnet or an electrically controlled actuator (for example a piezo actuator, an electromagnetic actuator or a pneumatic actuator). It is advantageous if the circuit board and the first sub-element are in one piece—the circuit board and the first sub-element therefore consist of one part. You can do this, for example, as a part stamped out of sheet metal.
- the first partial element is joined to the circuit board - the circuit board and the first Partial elements are therefore initially separate components which are connected to one another—preferably non-detachably—by a joining process.
- the first partial element can then be joined to the circuit board by forming, for example by caulking, by gluing, welding or soldering.
- the first sub-element is positively connected to the rest of the circuit board.
- the first partial element advantageously includes a coupling which engages in a form-fitting manner in a coupling point on the circuit board.
- the coupling point is advantageously a recess in the shank of the sinker, whose contour in the plane spanned by the sinker length direction and sinker height direction corresponds to the contour of the coupling of the first partial element and penetrates the shank in the sinker width direction.
- the sinker comprises a spurting area, which comprises the stitch-forming means and the front end of the shaft, which comprises 10-50%, but preferably 25-40%, of the longitudinal extent of the shaft, and which is the first partial element of the working pair contains.
- the expulsion area is the part of the sinker which protrudes from the sinker carrier in the longitudinal direction towards the stitch-forming tool during knitting operation.
- stitch-forming forces act on the sinker on stitch-forming means--for example, a hold-down edge--in the vertical direction of the sinker, which essentially act on the stitch-forming means when held down or cast off.
- the force that can be exerted by the action couple can counteract these stitch-forming forces. If both the loop-forming means and the first sub-element of the working pair are arranged in the ejection area, the result is short power transmission paths within the sinker, which are particularly advantageous.
- the first partial element - preferably a spring element - is arranged at a rear end of the shaft, which is opposite the front end of the shaft in the board longitudinal direction.
- the first partial element at least partially overlaps with the shank in the longitudinal direction of the sinker and has at least one partial region that is spaced apart from the shank in the vertical direction of the sinker. If the first partial element is arranged at the rear end of the shaft, it can advantageously be in contact with a partial area of a sinker carrier during knitting operation, and this partial area of the sinker carrier can be the second partial element of the working pair.
- the first partial element can be a spring element which is arranged at the rear end of the shaft and is supported on a contact surface in order to be elastically deformed.
- the contact surface can be part of the circuit board carrier and form the second partial element of the functional pair.
- the sinker has a drive foot, which is arranged at the rear end of the shaft and protrudes upwards beyond the adjoining area of the shaft in the sinker height direction, and the first partial element—preferably a spring element—in the sinker longitudinal direction between the drive foot and the drive-out area is arranged.
- the first partial element is then advantageously arranged on the shaft of the sinker. It is particularly advantageous if the first sub-element projects upwards beyond the surrounding areas of the shaft in the vertical direction of the board.
- the first sub-element When the first sub-element is arranged between the drive foot and the output area, it is advantageously in contact with a sinker cam during knitting operation, wherein the sinker cam can serve as the second sub-element of the working pair in order to exert a force with the working pair.
- the sinker comprises at least one sliding surface, which is assigned to the expulsion area and runs along the sinker width and sinker longitudinal direction of the shank, and whose surface normal in the sinker height direction of the shank is in the same direction as that of the pair of actions on the Board exertable force has.
- the sliding surface therefore points downwards essentially in the vertical direction of the board.
- the surface normal of the sliding surface has at least one directional component that points in the same direction as the force that can be exerted on the sinker by the acting couple.
- the sinker is rigid in the region adjoining the sliding surface in the direction of the sinker height—that is, not elastically deformable.
- the sliding surface can thus serve as a support with which the circuit board rests on a needle carrier—or on a part connected to the needle carrier—and ensures precise positioning of the circuit board in the vertical direction of the circuit board.
- the at least one sliding surface can be part of the basic sliding surface.
- the at least one basic sliding surface can also be separated from the basic sliding surface and spaced apart from the basic sliding surface in the vertical direction.
- the sinker comprises at least two sliding surfaces (e.g. the basic sliding surface and a further sliding surface), which are preferably spaced apart from one another in the longitudinal and/or vertical direction of the sinker.
- a sinker is also advantageous in which the at least one sliding surface at least partially overlaps with the first partial element--in the longitudinal direction of the sinker.
- At least partial areas of the sliding surface are therefore not at a distance from the first partial element in the longitudinal direction of the sinker.
- the sliding surface can be spaced apart from the first partial element, in particular in the vertical direction of the board. This results in a low mechanical load on the sinker and a permanently even mesh pattern can be ensured.
- the sinker (in addition to the Niederhai edge) comprises a further loop-forming means—preferably a knock-over edge for knocking off the just finished knitted fabric. It is particularly advantageous if the holding-down edge forms a groove in the sinker together with the further loop-forming means—preferably a knock-off edge, with the holding-down edge delimiting the groove in the vertical direction of the sinker and the knock-off edge in the downward direction in the vertical direction of the sink.
- the first partial element is a spring element which comprises a leg.
- This can advantageously be formed by an incision in the shank or delimit an indentation in the shank. This incision has an extension in the board longitudinal direction and the board height direction of the board.
- the spring element is elastically yielding or elastically deformable in the vertical direction of the board.
- the spring element withstands deformations even with repeated and oscillating loads.
- the spring element is advantageously designed as a spiral spring.
- the spring element is advantageously a leaf spring or flat spring.
- a spring element that has a spring stiffness of f00 cN/mm to 400 cN/mm, but preferably of 200 cN/mm to 350 cN/mm, in the vertical direction of the board is particularly advantageous.
- the spring rigidity is so great that with the possible spring deflection, a spring force of 20 cN to f00 cN pointing in the direction of the board height can be exerted.
- a spring element is particularly advantageous which, at at least one point of its longitudinal extension, has a greater height in the direction of the height of the board than its width in the direction of the width of the board.
- the first partial element is a spring element and the circuit board comprises a limiting element which is suitable for limiting the elastic deformation of the spring element in such a way that the limiting element is pushed to the second when a maximum elastic deformation of the spring element is reached sub-element of Effect pair and / or the spring element strikes.
- the limiting element serves as a stop and prevents further deformation of the spring element when it strikes the second partial element or the spring element.
- the limiting element is rigid - so it is not flexible like the spring element.
- a limiting element is particularly advantageous which has a rigidity in the direction of the height of the plate that is at least twice as great, but preferably at least five times as great as the spring stiffness of the spring element in the direction of the height of the plate. Further advantages result if the delimiting element has a rigidity of at least 400 cN/mm, but preferably at least 1000 cN/mm, in the vertical direction of the blank.
- the delimiting element is an arm, which adjoins the shaft in the expulsion area of the sinker in the longitudinal direction of the sinker at the front end of the sinker.
- the spring element overlaps with the delimiting element in the longitudinal direction of the board. Such a limiting element prevents overloading and thus failure of the spring element. At the same time, the force that can be exerted on the plate by the pair of effects is limited.
- a circuit board is also advantageous in which the leg comprises at least one section that is tapered in the direction of the height and/or width of the circuit board.
- the tapered section thus has a smaller height in the direction of the height of the plate and/or a smaller width in the direction of the width of the plate than regions of the leg adjoining it. It is advantageous to have a leg which, in the direction of the height of the board, has a lower height than its width in the direction of the width of the board.
- a guide region adjoins the tapered region at the front, which has a greater height in the vertical direction of the sinker than the tapered section and which is in contact with the second partial element of the working pair - preferably a contact surface of a needle carrier or a ring guide stands.
- a limb which comprises a dirt scraper which has a concave recess which is open on one side in the longitudinal direction of the board offers further advantages.
- a dirt scraper is advantageous which has a sharp edge at at least one outlet of the concave recess, which has an angle of less than 30° to the adjacent surfaces of the leg. With the dirt scraper, the accumulation of dirt - for example fiber abrasion - in the operating area of the board can be reduced.
- the object of the invention is also achieved by a knitting device with the following features:
- sinker carrier - preferably a sinker ring, which carries at least one sinker during knitting, which interacts with the at least one knitting needle during knitting and whose shank extends essentially in a sinker longitudinal direction,
- the sinker comprises a shank which extends predominantly in a longitudinal direction of the sinker
- the shaft has at least one stitch-forming means at its front end in its sinker longitudinal direction, which is in contact with the yarn during knitting and which participates in the stitch formation,
- the at least one stitch-forming means is a hold-down edge for holding down the just finished knitted fabric
- the at least one first partial element is part of the at least one sinker and the at least one second partial element is part of the rest of the knitting device.

- the sinker lock is suitable for turning the at least one sinker into an alternating knitting movement
- Customary knitting devices have a large number of sinkers.

- the shank of the sinker has at least one basic sliding surface, this basic sliding surface running in the longitudinal direction of the sinker and the sinker width direction of the shank running transversely to the longitudinal direction of the sinker, and the extension of the shaft in its vertical direction of the sinker running transversely to the longitudinal direction and width of the sinker is limited downwards and is such that the sinker can slide on it during knitting operations.
- the force that can be exerted by the working couple that is, the first partial element and the second partial element—acts on an expulsion area of the sinker, which comprises at least one loop-forming means and the front region of the shaft of the sinker, which is 5-30%, but preferably 10-20% the longitudinal extension of the shank of the sinker.
- the first partial element preferably a spring element
- the needle carrier includes the counter-element or is connected to the counter-element. It is particularly advantageous if the counter-element is arranged on a ring guide of a knitting cylinder, a sinker carrier or a sinker lock.
- the first sub-element and/or the second sub-element has a contact surface which encloses a pitch angle with the longitudinal direction of the board. At least during a phase of the knitting movement, the contact surface is in contact with the partial element of the working pair, which forms a working pair with the partial element which includes the contact surface.
- the contact can be in the form of a point, a line or a surface area.
- a surface contact enables an even distribution of the load on the two partial elements and thus increases the service life of the knitting device.
- the pitch angle of the contact surface is greater than 0 degrees at least at one point of its longitudinal extent in the longitudinal direction of the board.
- the contact surface has at least one partial surface that encloses an angle of inclination with the longitudinal direction of the board.
- the contact surface can run in the longitudinal direction of the circuit board - i.e. not enclose a gradient angle with the longitudinal direction of the circuit board.
- the pitch angle can also be of different sizes at different points of the sub-area.
- the pitch angle is the same at every point on the sub-area. It is particularly advantageous if the pitch angle of the partial surface has a gradient along its longitudinal extension in the longitudinal direction of the blank—that is to say increases or decreases (continuously) along the longitudinal extent of the partial surface.
- the contact surface has at least two partial surfaces which enclose an angle of inclination greater than 0 degrees with the longitudinal direction of the board.
- the contact surface can then advantageously run in the longitudinal direction of the board - i.e. it does not include an angle of inclination with the longitudinal direction of the board (the angle of inclination is equal to zero).
- the contact surface has at least two sub-surfaces which enclose different pitch angles with the longitudinal direction of the board.
- the cutting edge of the contact surface (or at least a partial surface of the contact surface) lying in an LH plane spanned by the board length and board height direction has a constant radius around a central axis running in the board width direction.
- the sinker in knitting devices usually performs a knitting movement in the longitudinal direction of the sinker.
- at least one of the two partial elements, which interacts with an inclined contact surface performs a lifting movement in the vertical direction of the sinker during the knitting movement of the sinker in order to be permanently connected to the contact surface during the knitting movement.
- the contact surface is a surface of a knitting cylinder or a sinker cam pointing downwards at least in sections in the sinker height direction.
- the angle of inclination of the contact surface and/or the partial surface of the contact surface is 0.5 to 22 degrees, but preferably 2 to 10 degrees.
- the selection ranges mentioned have proven to be particularly advantageous in knitting devices with sinkers of conventional dimensions.
- the sinker in the knitting device can advantageously assume at least two positions in which the force acting on the sinker by the acting couple is of different magnitude. In the at least two positions, the sinker is driven forward to different extents in the longitudinal direction of the sinker.
- the force acting on the sinker by the acting couple is greater in a first position of the sinker than in a second position of the sinker, the sinker being driven further forward in the longitudinal direction of the sinker in the first position than in the second position.
- the front is the direction in which the front end of the sinker also points—in a knitting device, the front end of the sinker points in the direction of the needle carrier.
- the first partial element and/or the second partial element is a spring element, it is advantageous if the spring element is elastically bent to different extents in these at least two positions in the board height direction.
- the force in a hold-down position of the sinker is 40 cN to 100 cN, but preferably 50 cN to 70 cN, the sinker in the hold-down position being pushed forward in the longitudinal direction of the sinker in the direction of the needle carrier as far as possible.
- the stitch-forming force acting upwards in the sinker height direction which usually acts on the sinker via the stitch-forming elements during the stitch formation, is greatest. If the sinker force in the hold-down position is in the above-mentioned selection range, an offset movement of the sinker in the sinker height direction upwards and thus irregularities in the stitch pattern are prevented in this position.
- the first sub-element and / or the second sub-element is a spring element which is most elastically deformed in the hold-down position of the board is particularly advantageous.
- the spring element is most elastically deformed in the vertical direction of the sinker in the hold-down position of the sinker.
- the second partial element is either part of the sinker lock or is attached to the sinker lock.
- the first partial element is a spring element which is arranged on the shaft of the sinker in the longitudinal direction of the sinker between the drive foot and the drive-out area of the sinker.
- the second partial element, which is part of the sinker lock or is attached to the sinker lock is a contact surface that is in contact with the spring element at least during a phase of the knitting operation, the spring element deforming elastically when in contact with the contact surface in the vertical direction of the sinker.
- the object of the invention is also achieved by a knitting method with the following features:
- At least one knitting needle performs knitting movements in which the knitting needle moves (mainly) alternately along a longitudinal direction of the needle, which extends along the needle shank,

- FIG. 11 shows a knitting device 14 with a sinker 1 which includes a spring element 22 which is arranged in the longitudinal direction L between a drive foot 28 and the exit area 8 .
- Figure 1 shows a knitting device 14 with a needle carrier 15, a sinker carrier 17, a sinker lock 33 and a sinker 1.
- the sinker 1 has a shaft 2 which extends essentially in the longitudinal direction L of the sinker and which is located in a groove 21 of the board carrier 17 is arranged.
- a loop-forming means 3 At the front end of the sinker 1 in the longitudinal direction L of the sinker, a loop-forming means 3 in the form of a hold-down edge 10 and a first sub-element 6 of an active pair in the form of a spring element 22 are arranged.
- the needle carrier 15 carries a knitting needle 16, the needle shank 23 of which is in the longitudinal direction N runs.
- the longitudinal direction of the needle N essentially points in the vertical direction H of the sinker and thus runs perpendicularly to the longitudinal direction L of the sinker.
- the teaching according to the invention can advantageously be used with all conceivable angles between the longitudinal direction N of the needle and the longitudinal direction L of the sinker.
- the sinker 1 rests with its basic sliding surface 4 on the sinker support 17 and can slide back and forth on the sinker support 17 driven by the sinker lock 33 during its alternating knitting movement in the longitudinal direction L of the sinker. In the illustrated position of the sinker 1, the sinker 1 is in its hold-down position, that is to say pushed out as far as possible in the direction of the needle carrier 15.
- Figure 2 shows detail A of Figure 1: the contact surface 31 is inclined by a pitch angle 20 to the sinker longitudinal direction L, that the spring element 22 is elastically deformed during the knitting movement of the sinker 1 in the sinker longitudinal direction L through contact with the contact surface 31 so that a force 7 pointing in the vertical direction H of the board is exerted on the board 1 .
- the driving force required for this, acting in the longitudinal direction L of the sinker, is exerted on the sinker 1 by the sinker lock 33 .
- the spring element 22 is then elastically deformed to an increasing extent in the vertical direction H of the board in a phase with increasing ejection 36 of the board 1 - consequently the action couple exerts a force 7 on the board 1, which increases with increasing ejection 36 of the board 1 increases.
- the force 7 acts at the point of contact between the spring element 22 and the contact surface 31.
- the force 7 acts perpendicularly to the contact surface 31 on the circuit board 1.
- the force 7 thus has a longitudinal component 26 pointing in the longitudinal direction L of the circuit board and a height component pointing in the vertical direction H of the circuit board 27, with the height portion 27 being greater than the longitudinal portion 26. Due to the force 7, the board 1 is pressed downwards in the board height direction H, so that it rests with its sliding surface 9 on the upper side of the needle carrier 15 during the knitting movement.
- FIG 3 shows an exemplary embodiment of a needle carrier 15 and a sinker 1, the shaft 2 of which extends in the longitudinal direction L of the sinker.
- the shaft 2 At its front end 5 in the longitudinal direction L of the sinker, the shaft 2 has a loop-forming means 3 in the form of a hold-down edge 10 .
- the sinker 1 can hold down stitches on the needle shaft of a knitting needle with the hold-down edge 10, while the knitting needle performs a knitting movement in the longitudinal direction of the needle upwards.
- a first partial element 6 of an active couple in the form of a spring element 22 is arranged in an expulsion area 8 of the blank 1, which includes the front end 5 and the hold-down edge 10.
- the spring element 22 is shown in two different states: the contour with the solid line shows the spring element 22 in a completely unloaded, ie not deformed, state. This corresponds to the state of the spring element outside of a knitting device. This contour is also shown as if it were in front of the needle carrier 15 shown in section, which of course is not the case.
- the contour with the dashed line shows the spring element 22 in that operating position in which the circuit board is driven out to the maximum.
- the spring element 22 is thus elastically deformed in the vertical direction H of the board.
- the spring element assumes this state—or this operating position—at least during a phase of the knitting movement in a knitting device.
- the spring element 22, together with a second sub-element 18 of the pair of effects, is suitable for exerting a force 7 which acts downwards on the board 1 in the direction H of the board height.
- the second partial element 18 includes a contact surface 31 of the needle carrier 15, with which the spring element 22 is in contact during the knitting movement, and which is arranged such that the spring element 22 is elastically deformed in the vertical direction H of the sinker.
- the contact surface 31 At its rear end in the longitudinal direction L of the board (in the direction of the board carrier), the contact surface 31 has a partial surface 39 which encloses an angle of inclination with the longitudinal direction L of the board.
- This gradient angle changes along the longitudinal extension of the partial surface 39 in the longitudinal direction L of the blank in such a way that the cutting edge of the partial surface 39, which lies in the LH plane, has a constant radius 40 around the central axis 41 at every point - the cutting edge is therefore part-circular.
- the limiting element 38 is in contact with the contact surface 31 and prevents further Upward movement of the sinker 1 in the sinker height direction H, so that the spring element 22 cannot be further elastically deformed beyond the elastically deformed state shown in FIG.
- the limiting element thus limits the deformation path of the spring element 22.
- the spring element 22 in a state in which it has already reached its maximum deformation that it experiences during operation.
- the force 7 is exerted on the circuit board 1 by the pair of effects.
- this force 7 is at its maximum (greater than in the other operating states).
- the shaft 2 At its rear end 32 in the longitudinal direction L of the plate, the shaft 2 has a drive foot 28 .
- the drive foot 28 is suitable for being in engagement with a sinker cam in order to drive the sinker 1 into a knitting movement, the knitting movement being an alternating movement that runs essentially in the longitudinal direction L of the sinker.
- the sinker can slide on a sinker carrier on a basic sliding surface 4, which delimits the shaft downwards in the sinker height direction H.
- the sinker lock and the sinker carrier are not shown for the sake of clarity.
- the sliding surface 9 is part of the basic sliding surface 4 and overlaps with the spring element 22 in the longitudinal direction L of the plate Direction.
- Figure 4 shows another embodiment of a needle carrier 15 and a circuit board 1.
- the spring element 22 is shown in two different states: the contour with the solid line (again in the "foreground” in front of the needle carrier 15 shown in section) shows this Spring element 22 in a fully unloaded, ie not deformed state. This corresponds to the state of the spring element outside of a knitting device.
- the contour with the dashed line shows the spring element 22 in its operating position, in which the spring element 22 is elastically deformed in the vertical direction H of the board.
- the spring element assumes this state at least during a phase of the knitting movement in a knitting device.
- the partial surface 39 is not part-circular, but encloses a consistently large angle of inclination with the longitudinal direction L of the plate at every point of its longitudinal extent in the longitudinal direction L of the plate - the partial surface 39 is therefore a flat surface that encloses an angle with the longitudinal direction L of the plate.
- the knock-over edge 24 is suitable for knocking off the knitted fabric produced so that it detaches from the knitting needles.
- the hold-down edge 10 and the knock-off edge 24 together form a groove 34 which is arranged in the expulsion area 8 of the blank 1 .
- the sliding surface 9 rests on the upper side of the needle carrier 15 and aligns the sinker 1 in its expulsion area 8 in the vertical direction H of the sinker by being pressed against the upper side of the needle carrier 15 due to the force 7 exerted on the sinker 1 by the acting couple 6, 18 .
- the spring element 22 is shown in broken lines in its elastically deformed state. In this state, the elastic deformation that can be achieved during the knitting operation due to the position of the sinker has reached its maximum.
- the limiting element 38 hits the contact surface 31 (second partial element 18) and thus prevents further deformation of the spring element 22, which goes beyond the illustrated elastically deformed state of the spring element 22 (dashed contour).
- the limiting element prevents the spring element 22 from being overloaded in the event of short-term peak loads acting on the spring element 22 . Without such a limiting element 38, the spring element 22 could be plastically deformed or even break if the load peaks were too high, so that the entire sinker 1 would have to be replaced for the knitting operation to continue without errors.
- Figure 5 shows a further exemplary embodiment of a sinker 1 with a shaft 2, a holding-down edge 10, a knock-off edge 24 and a basic sliding surface 4.
- the expulsion area 8 of the sinker 1 comprises a sliding surface 9 and a first partial element 6 in the form of a spring element 22
- the spring element 22 comprises a leg 11 which is formed by an incision 12 in the shank 2 of the circuit board 1 .
- the incision 12 extends in the board longitudinal direction L and in the board height direction H and completely penetrates the board 1 in the width direction B.
- the leg 11 comprises a tapered section 13, in which the leg 11 is tapered in the vertical direction H of the board.
- the spring stiffness of the spring element 22 can be reduced in such a way that in Interaction with a second sub-element 18 of the pair of effects adjusts the spring force required for the knitting process.
- the leg 11 is tapered in the width direction B in the tapered section 13 .
- a guide region 35 adjoins the tapered section 13 in the longitudinal direction L to the front. In the vertical direction H of the board, the guide region 35 is greater in height than the tapered section 13 and is spaced apart from the sliding surface 9 in the vertical direction H of the board by the clear dimension 42 .
- the guide area 35 is suitable for knitting with components of a knitting device - for example a needle carrier - to be in contact and to guide the spring element 22 along a second partial element 18 of the working pair - for example a contact surface.
- the sinker 1 from FIG. 5 is shown in FIG. 6 together with a needle carrier 15: during the knitting movement of the sinker in the longitudinal direction L of the sinker, the sinker 1 is moved back and forth on the needle carrier 15.
- the sinker 1 slides with its sliding surface 9 on the needle carrier 15.
- the needle carrier 15 comprises a second partial element 18 with a contact surface 31 which is in contact with the spring element 22 of the sinker 1. Sections of the second partial element 18 have a greater height in the vertical direction H of the board than the clear dimension 42 (cf. Fig. 5) of the incision 12 in the circuit board 1 in the vertical direction H of the board elastically deformed in the sinker height direction H during the knitting movement of the sinker 1.
- the contact surface 31 comprises a first partial surface 43 and a second partial surface 44, each of which enclose an angle of inclination to the longitudinal direction L of the board, the first angle of inclination 45 between the first partial surface 43 and the longitudinal direction L of the board being greater than the second angle of inclination 46 between the second partial surface 44 and the longitudinal direction L of the sinker.
- the contact surface 31 runs in the longitudinal direction L of the sinker. This results in a following during an ejection movement of the sinker 1 in the longitudinal direction L of the sinker (in the direction of the needle carrier 15). Described course of force 7: in a completely retracted state of the circuit board 1 (In its knitting movement, the sinker is drawn in as far backwards as possible in the longitudinal direction of the sinker) the sinker 1 initially has no contact with the spring element 22—no force 7 is exerted.
- the spring element 22 then comes into contact with the first partial surface 43 and is elastically deformed due to the inclined course of the first partial surface 43 with the first gradient angle 45, so that the working pair consisting of the contact surface 31 and the spring element 22 a force 7 is exerted, which increases with increasing ejection of the circuit board 1 until the spring element 22 is in contact with the section of the contact surface 31 which is arranged between the first and the second partial surface 43, 44 and runs in the longitudinal direction L of the circuit board. While the spring element 22 is in contact with this section, the force 7 exerted is constant and at a maximum (maximum force in normal knitting operations). With the continuous ejection movement of the sinker 1, the spring element 22 is then in contact with the second partial surface 44 and the force 7 exerted decreases again due to its inclined course with the pitch angle 46 with increasing ejection of the sinker 1.
- FIG. 7 shows another exemplary embodiment of a needle carrier 15 and a sinker 1 with a shaft 2, a low-profile edge 10, a knock-off edge 24, a basic sliding surface 4 and a sliding surface 9.
- the force element 6 in the form of a spring element 22 is a single part , which is joined to the shaft 2 of the circuit board 1.
- the spring element 22 is shown in two different states: the contour with the solid line shows the spring element 22 (again in the "foreground" in front of the needle carrier 15 shown in section) in a completely unloaded state, i.e. not deformed, condition. This corresponds to the state of the spring element outside of a knitting device.
- the contour with the dashed line shows the spring element 22 in its operating position, in which the spring element 22 is elastically deformed in the vertical direction H of the board.
- the spring element assumes this state—or this operating position—at least during a phase of the knitting movement in a knitting device.
- the spring element 22 includes a coupling 29 which engages in a coupling point 30 of the shaft 2 in a form-fitting manner.
- the coupling point 30 is a recess in the shaft 2 of the sinker 1, the contour of which in the LH plane spanned by the sinker length direction L and sinker height direction H corresponds to the contour of the coupling 29 of the spring element 22 and penetrates the shaft 2 in the sinker width direction B.
- this embodiment of the sinker 1 is otherwise similar in its functions to the sinker 1 from FIG with this contact surface 31 a working couple which exerts the force 7 pointing downwards in the vertical direction H of the sinker onto the sinker during the knitting operation.
- the spring element 22 is elastically deformed (dashed contour).
- the delimiting element 38 is not in contact with the contact surface 31 .
- a further elastic deformation of the spring element 22 beyond its elastically deformed state shown in dashed lines is possible.
- the tip of the spring element 22 in this exemplary embodiment would touch the limiting element 38 when it reached its maximum elastically deformed state. This contact would prevent further deformation of the spring element 22 with the aid of the limiting element 38 .
- FIG. 8 shows another exemplary embodiment of a sinker 1 with a shaft 2, a hold-down edge 10, a knock-off edge 24, a basic sliding surface 4, a sliding surface 9 and a spring element 22, which includes a leg 11 with a tapered section 13.
- the spring element 22 is shown in two different states: the contour with the solid line shows the spring element 22 in a completely unloaded, ie not deformed, state.

- the spring element 22 is formed by an incision 12 in the shank 2 of the board 1 .

- the force 7 that can be exerted by the active couple at the beginning of the ejection movement of the blank 1 when the spring element 22 comes into contact with the first partial surface 43 initially increases sharply.
- the force 7 continues to increase when the spring element 22 comes into contact with the second partial surface 44 as the blank 1 ejects more and more.
- the force 7 increases less than when in contact with the first partial surface 45 (larger first pitch angle 45) at the beginning of the ejection movement.
- the greatest possible force 7 is applied at an early point in time of the ejection movement in order to stabilize and precisely position the plate 1 during its ejection movement, but without generating an unnecessarily large force 7 at a later point in time of the ejection movement.
