Description

The present invention aims to simplify and accelerate the production of knitted products, which are given the property of not stretching in the longitudinal direction and across the seams.

In FIG. 1 shows a longitudinal section of the machine; FIG. 2-20- - machine parts; FIG. 21 and 22 are other forms of the machine.

The machine is equipped with a fixed needle wheel / carrying needles 2 on its upper surface. Cams 3, which are louvre relative to the circle /, tell the needles forward-return / displacement. Needle 2 radially protrude. Inside the circle.

The control needles in the die cams 3 are mounted on the sled 4, mounted, in turn, on the 5-segmented 5 mounted on the gear b, and the number of these segments corresponds to the number of machine feeds.

Ring needle circle / support. on the protruding inside the shoulders L (outer casing.

The ring gear b, and, therefore, the cams 3 are painted directly above the annular needle wheel / and concentrically around it ,; where

(.KM)

Each .5 segment carries a set of cam cams, different in type and number, depending on the size of the machine and the nature of the material being produced.

The needles 2 are tongue needles and operate with a diverter 7 attached to the circle / at. using plates 8 and gaskets S (i (fig. 6). These gaskets can be from Ainz or from any other material and serve to ensure reliable clamping.

The gear wheel 6 moves along a roller 9 rotatably mounted on ball bearings or in some other way on fingers} 0 attached to racks // machines on which they can be replaced.

The machine is set in motion from the vertical shaft / 2, which imparts the danger to the crown, through gear / 3 that is in gearing with it.

A gear 19 interlocking with the teeth on the needle wheel / rotates the spreading wheel 20 for the weft yarn through the spindle 2 /, rotatably mounted with U of each of the segments 5, and this spreading wheel 20 adjusts the feed of the threads to the needles in a well-known manner.

A ring 22 of angular section is supported around the toothed ring b, supported on corresponding rollers, for example 23. This ring 22 covers the teeth of the ring b and is provided on its upper edge with ratchet teeth with which finger-2 / engages in case of breakage or excessive loosening of weft threads j6a. When the finger 24 is engaged with the stored teeth on the ring 22, the latter moves on the rollers 23 in time with the crown 6 and the vertical leash 25 is displaced relative to the machine frame and acts on the corresponding coupling 26, disengaging the drive shaft / 2 with its drive mechanism , and that stops maschina. Instead of the coupling 26, the driver 25 may, shifting, act on the motor switch, on the device for stopping the belt, or on any other device for stopping the machine. In addition, the ring 22 can be provided with a handwheel or the like to control it by hand.

Base threads / 7, which are non-core yarns, are removed from brake drums 18 mounted tangentially to the frame of the machine. These warp threads run down between the teeth of spring loaded spring loaded

ridges 27 or so on, of which there are several for each drum. These ridges support the warp in the tensioned state, and since there are several of them. each, depending on the conditions

work. The warp threads 17, t from the wobbly ridges 27, are passed through one or more ring ridges or guide rings. There are two 28 and 29 such annular ridges, and the threads pass between their teeth in order to occupy the required position in the middle between the neighboring needles 2 on the needle wheel /.

 One of the RING ridges 2S, 29 or both of these ridges can be replaced with rings with filament guide holes, the openings can be spaced so that large holes can be used. On the top of the machine, above the drum for the warp threads, is placed a second gear ring 30 supported on wheels 9h mounted on bolts 10 (t, which can be mounted on machine racks. // This upper ring gear is driven from shaft 72 via gear 31 and is held in a position concentric with the needle wheel /, with the aid of a sleeve 32 rotatable mounted on the central shaft 33 of the machine suspended and attached to the thickening 34a of the fixed upper part 34. The gear rim 30 is connected by a radial tug J5 to a rotating With sleeve 32, a second ring 22 "of angular section with ratchet teeth and a pivot pin 24a corresponding to its purpose and method of operation ring 22 around the ring crown 6 can be placed around this gear ring.

The upper ring gear 30 carries bundles of threads J (J, from which they are fed inside the circles of the warp threads 17 into the Zba filament yarns, and this rim 30 also carries rotating feeding devices J7, driven by gears 39, which are driven by rolling around the fixed gear 40 attached to the uprights //. Zba threads are tightened by spring-expanding members 38 or the like.

On the sub central axis 33 of the machine, a part // is rotatably mounted, resting on another part 42 on the same shaft, and part 42 is provided with fist accessories or the like for vertical shifting part 41 relative to needles. Part 41 is driven from upper toothed end 30 via one or more arms 43 or other suitable parts. Cone - //, made in the form of a wheel, carries organs 44, equipped with thread guides, laying the threads 36 in the form of weft a 2. The organs 44 also carry tongs

-n.

and tongs openers (where tongue needles are used) or clamps (where barbed needles are used), and clamps 45 for warp threads and clamps 45a for material (Figures 11, 12 and 13).

A stretcher 47 for round products, the diameter of which maintains a round shape and note of the product when it is removed from the needles, is placed lower in the hall level and in the corresponding distance from it. Adjustable stretcher 4S, suspended by one. or several rods 49 to said stretcher 47, maintains the product in the tensioned state during the passage of the products between the respective shooting rolls 50 and 51,

These survey rollers are mounted in bearings 52 and driven from drive shaft 12 through bevel gears 55, shaft 54, bevel gears 55, gears with interchangeable gears 56 and differential gear 57 (Fig. 1). Bearings 52 reversible rollers 50 and 5 / are mounted on the main plate 58 of the machine between the bearings 59, in which the drive shafts rotate. / 2.

Arrangement in the jaw cams, tool For laying the threads, clamps and other organs associated with the loop-forming mechanism can be changed in different ways, according to the nature of the material being produced, and the needles 2 can be provided with projections of various heights. FIG. 2 shows a stage in a knight in which the weft thread / ba is laid alternately above and below the needles, and laying over the needles is done so that (if the weft thread could be

gzpt in fleece with the set intervals. Some of the needles have a ring-shaped protrusion 2 (Z (Fig. 5), a half of the remaining needles have a protrusion located L. in 2c, and a cam mechanism controlling the sluggish needles is so designed that the needles with protrusions 2a are always in the thread of Zba

1Ы2. but never the weft threads J6 ({, needles with protrusion 26 and with protuberances 2c insert ducks / 5a, with needles with protrusion 2b and 2c, introducing

- 3 weft thread / 6fJf, not inserted into the main thread Zba. -

FIG. 6,7,8 and 9 shows organs laying ducks. Each of these organs is attached to one of the segments 5, provided with a conical shaped expanding arm 4bp mounted in a bearing attached to the segment. Each razdigatel 46a has on its outer surface a shoulder or flange to which the disk 4b is attached, so that a guide and safety groove for the weft / da is formed around the feeding device. Some of the bracket bodies 46, adapted to hold the weft yarn under the needles, are equipped with fixed fingers 46c on the non-supply side of the organ and partially in a circular head, and this finger extends to the lower side of the bracket and carries wire 46d at its lower end. that the hooked ends of several needles, which are controlled by the cam claws, always arrive on the upper side of the wire 46d, and since the weft 16a passes under this wire, the latter is forcibly guided under the needles.

Some brackets 46 are provided with a second finger, which is removable and placed on the supply side of the bracket, and also partially in a circular groove and ends at the bottom with a point or fork.

In the event that the weft yarn 16ii is broken, such a finger 46c is removed, and the end of the dangling thread, pulled from the magazine, is wound on the end of the finger, which is then fixed in place again. In this case, the severed end of the thread is placed directly in front of the spreading end 46h so as to be in contact with the material hanging from the needles, and due to the fibrous structure of the kit in this material, the severed end engages the material and the weft thread is reintroduced.

One of the brackets used in each stage in the yoke is provided with only a finger of the 46th and, in view of the absence of a finger of 46c with a wire, this organ will obviously put a weft thread over the needles. On this ridge organ, the finger is balanced on its axis of rotation so that in case of breakage or excessive sagging of the thread 16ii, the finger leaves the equilibrium position and turns back. A spring 69 is provided, so adjusted that its normal resistance is sufficient to turn the ratchet ring 22, with the ring crown 6, when the finger 24 engages with the ring 22. If something prevents the ring 22 from turning, the spring 69 will fail and prevent a breakdown the noise produced by sliding the finger 24 along the teeth of the ratchet ring will attract the attention of the worker. The pin head 70 associated with the finger 24 is cut to 70a so that the finger can rotate normally on its axis of rotation without the action of a spring. FIG. 20 shows an exemplary embodiment of a differential gearing that can be included in the camera busting of the shooting rollers 50 and 51 from the vertical driving shaft 12. Here, the wheel 77 is attached to the roller 5 /, and the wheel 78 to the subframe 52. The box-shaped wheel 57 carries the gear 80 The gear with wheels 77 and 78 rolls around them and is driven by interchangeable gear 56. The difference and the number of teeth of wheels 77 and 78 determine the degree of speed reduction, which is adjusted to the conditions of work, and the direction of rotation of the rollers depends on the number of teeth of the wheel. attached to the driven roller. Instead of the differential gear described here, any other differential gear can be used. FIG. 21 shows a modified form of a circular arrangement in a die machine with a zonal position outside the ring / carrying the needles, and into the hall, cams, stackers, duck feeders and associated mechtones are placed inside the base 17. When the device is driven into the hall jaws, the drive The upper gear ring 30 moves in motion, and the lower gear ring carries the feeders in the filament yarn, organs for in the filament yarn, and parts connected with them. FIG. 22 shows another embodiment of the machine. Here the machine is supplied (on the third toothed rim. With such a device, an open magazine of warp / 7 and guide rings 29 and 29a can be used for a low warp, for a complete: | set of warp threads, which allows the use of various thread magazines. laying the weft yarns inside the warp of the warp, stump of the warp of the warp and inside of the warp of the warp in different order to put them in any way. Obviously, when laying the weft into the warp of the warp strings, the warp threads tightly catch the weft and In order to facilitate the creation and patterning of knit patterns, the needles on the machine and the number of feeds for weft threads can be chosen so that it has many dividers. For the same purpose, all known adaptations can be used to select needles. These are standard wheels, cylinders, chains, and their accessories. Subject of the patent: 1.
