Description

Loom for producing a cross-sectionally profiled fabric, in particular a rope

Technical Field

The invention relates to a weaving machine for producing cross-sectionally profiled fabrics, in particular ropes, according to the preamble of claim 1.

Background

Ropes are usually manufactured by rope stranders or braiders, wherein there are disadvantages that these machines are limited in their capacity and that only ropes of limited length can be manufactured.

US2130636 describes a weaving machine for producing tapes, i.e. flat fabrics, of the type mentioned in the introduction, in which a fabric support is assigned to the weaving position in the usual manner. The textile support is used only for supporting the already flat textile strip and therefore has no influence on the shaping. DE20000593 describes a device for producing a curved belt, which is connected downstream of a weaving machine as an additional device. This attachment has two take-up rolls between which the finished strip is bent but the cross-section of which cannot be changed. US4467838 describes an apparatus which is connected downstream of a weaving machine and from which the tape produced is made into a three-dimensional hollow body.

Disclosure of Invention

The invention is based on the object of designing a weaving machine such that it is suitable for producing fabrics, in particular ropes, with a profiled cross section.

The above-mentioned object is achieved by a weaving machine according to claim 1. By providing the weaving position forming the forming fabric with a fabric support with a shaping opening, the cross section of the shaping opening of which is substantially identical to that of the forming fabric with a circular or polygonal cross section, the warp threads are bundled according to the desired shape of the forming fabric on the basis of the shaping opening and are fixed in a defined position by means of the inserted weft thread loops and the tying thereof. It is thus possible to produce long lengths of profiled fabric, in particular ropes, on a weaving machine in a simple manner and at high speed.

The term "warp" is to be understood very broadly in this case and encompasses not only yarns but also other elongated items fed in the form of warp, which in turn may be profiles or reinforcing linings, and shaped products made by weaving, knitting, braiding, etc.

An advantageous further development of the weaving machine is specified in claims 2 to 16. The fabric support of claim 2 wherein the shaped aperture is substantially circular. Shaped apertures having a substantially oval or elliptical cross-section are also contemplated. According to claim 3, the cross-section of the shaped openings can also be in the form of regular or irregular polygons, in particular triangles or rectangles.

According to claim 4, the fabric support advantageously has a feed slot, which is formed along the length of its shaping opening, for the introduction of warp threads. The insertion slot is designed here to prevent the inserted warp threads from slipping out. For this purpose, according to claim 5, the insertion slit is preferably designed in a wave-like manner. It is also advantageous if the fabric support is designed to be separable in the direction of its shaping opening, so that it is possible to access the shaping opening by removing parts of the fabric support in order to introduce warp threads.

According to claim 6, advantageously in the warp feeding device before the shedding device, a heddle is present for each warp thread, prestressed transversely to the running direction of the warp thread, for balancing the varying tensile stresses or length differences between adjacent warp threads occurring during weaving. According to claim 7, at least one warp thread feed device and a corresponding tensioning device can be provided for a large-diameter warp thread used as a spacer thread. Suitably, according to claim 8, each heddle or pinch roller is connected to a contact for signalling a fault when the warp tension is insufficient.

It is particularly advantageous if the weaving machine according to claim 9 has a fabric take-up mechanism which has a plurality of deflection points, preferably 5 to 15 deflection points, for the forming fabric. This ensures a secure drive of the forming fabric on the fabric take-up mechanism and prevents the forming fabric from being deformed as would occur in a conventional fabric take-up mechanism. The stress in the finished forming fabric can also be reduced by these turning points. The fabric take-up mechanism preferably has a mechanical or electromechanical drive, in which case it is advantageous if the ratio of take-off speed to loom speed can be controlled or adjusted preferably by means of an adjustable transmission or an electronic control.

The fabric take-up device can have two take-up rolls arranged in parallel, at least one of which is driven, and on which the profile fabric is guided in a plurality of windings. According to claim 11, the take-up rolls have diameters which differ from one another, which is used to improve the stress reduction in the forming fabric. It is particularly advantageous if, according to claim 12, the winding roller has a section with a larger diameter than in the remaining region for the final winding. The drawing properties can be improved by a design according to claim 13, in which case at least the driven take-up roller has a non-slip surface. It is particularly expedient if, according to claim 14, the weaving machine has deflection points with a receiving profile which is adapted at least to the cross-sectional shape of the forming fabric in order to improve the quality of the shape retention of the forming fabric.

A method according to claim 15, including the step of installing a stretching roller between the fabric support and the fabric take-up mechanism for partially stretching the forming fabric to reduce internal stresses in the finished forming fabric. The stretching roller is preferably arranged to bend the forming fabric downwards and is arranged substantially centrally between the fabric support and the fabric take-up mechanism.

Such a weaving machine is particularly advantageous if the fabric support is arranged so as to be pivotable through a defined angle about an axis transverse to the weaving direction, i.e. substantially parallel to the weft direction (claim 16). Especially in the weaving of ropes, where a weave circulation is usually used, in which the ratio of warp threads distributed in the upper shed to warp threads distributed in the lower shed (and vice versa) is three-quarters to one-quarter, or even more different (for example one-eighth to seven-eighths), geometrical problems arise, especially in knitting machines, in which the insertion needle may freely pass through the weft insertion (durchhsuss). Even for a partially thick warp thread, for example a thick means a core of a central warp thread, which means an average warp thread, the warp threads in the area outside the weft thread area (and in particular also the core) can still be raised and lowered easily. The effect achieved in this way can be further improved if the fabric support, although having an aperture cross section in the front molding zone which substantially corresponds to the cross section of the forming fabric to be produced, is expanded in the rear zone, i.e. has a substantially straight, parallel-sided upward and downward oval expansion when round ropes are to be woven. The rotary movement of the fabric support is thus supported by the shaping. For the sake of illustration, it should also be pointed out that, in the case of a square shaped cross section of the fabric support, the rear cross section is then preferably rectangular. The design of such a molding fabric support with a pivoting movement according to the invention has the outstanding advantage that the rise and fall in the opening of the warp threads can be reduced when the same rope thickness or the same thickness of the core is to be achieved, without at the same time disturbing the free movement capability of the weft insertion needles or at most the further weft insertion device, in comparison with weaving machines without pivoting measures. Since the lifting and lowering during the opening of the warp threads has a great influence on the weaving speed, this measure can be used to achieve an increase in the weaving speed with a smaller lifting and lowering necessary during the opening of the warp threads. On the other hand, by using a weaving machine which takes such measures as advantageous embodiments with regard to the warp shedding, a greater profile thickness (for example, a thicker thread) and a thicker weaving core can be achieved. In principle, the swiveling motion can be driven from the outside. In a preferred embodiment, however, the pivoting movement is carried out freely and by the yarn rising and falling. Furthermore, a pivotable fabric support can also be used in conventional weaving machines, in which the fabric support is designed as a spreader for the band-shaped woven fabric.

The components used according to the invention, which are mentioned above and claimed and are described in the following examples, have no special exceptions with respect to their size, shape, use of materials and their technical design, so that the selection criteria known in the respective field of application can be used without limitations.

Detailed Description

Fig. 1a and 1b show a weaving machine in a schematic side view and plan view, with a warp thread 4 feed device 2. By means of the opening device 6, the warp threads 4 are opened into a shed 8, so that a weft thread loop 12 of a weft thread 14 can be introduced into the shed 8 with a weft insertion needle 10. The weft thread loop 12 is tied off on the side facing away from the insertion side by means of a knitting needle 16. The weft loops 12 may be interwoven with weft loops 12 that have been previously introduced, but the tying is preferably done with the aid of an auxiliary yarn 18. Advantageously, the tying is carried out with the prevention of unraveling of the inserted weft thread loops 12. In the weaving position 20, the inserted and bound weft thread loops 12 are stopped by means of a reed 21 and fed to a fabric support 22, which has a shaping opening 24 whose cross section corresponds substantially to the cross section of the forming fabric 26 to be produced. The warp threads 4 have been held in the desired shape of the finished forming fabric 26 in the weaving position 20 by means of the shaping openings 24 and this shape is fixed by the inserted and bound weft thread loops 12.

Fig. 2-4 illustrate fabric supports 22a, 22b and 22c having different shaped apertures 24a, 24b and 24c, which may have circular, oval and polygonal, e.g., quadrilateral, cross-sections. The fabric support is designed to be split along its horizontal mid-plane so that a portion can be removed for easy introduction of warp yarns. However, it is also possible to provide a feed slot, not shown in the figures, for the introduction of warp threads, for example, on the fabric support side along the middle plane. In order to make it difficult for the warp threads to slip out, the insertion slot can be designed in a wave-shaped manner.

Figure 5 shows a longitudinal section of the fabric support 22. To reduce the frictional resistance of the forming fabric in the shaping opening 24, it may have a cross-section which expands a small amount in the direction of travel of the forming fabric. The forming fabric 26 exiting from the fabric support 22 is taken up by means of a fabric take-up 28, on which the forming fabric is guided in a multiply wound manner, in order to achieve a safe take-up of the forming fabric and to prevent deformation of the forming fabric.

The fabric take-up device 28 has two rollers 30, 32 arranged at a distance from one another, wherein the roller 30 facing the fabric support 22 has a smaller diameter and the roller 32 facing away from the fabric support 22 has a larger diameter. For the last winding, the roller 32 has a section 34 which has a diameter which is enlarged again in order to be able to smoothly discharge the forming fabric 26. The smaller diameter guide roll 36 forms the entrance to the fabric take-up 28. In order to feed the forming fabric 26 to the last section 34 of the roll 32, a safety device 38 is additionally provided, in order to ensure that the forming fabric 26 is safely carried along in this section 34 and that a warning signal is emitted in the event of a malfunction. The rolls 30 and 32 may be provided with an anti-slip coating and/or with a receiving profile 40, which is adapted to the cross-section of the forming fabric 26 being produced, as can be seen in fig. 6 to 8. The design according to fig. 9 is particularly advantageous, in which the receiving profile 40 is designed such that the chord (chord) of the forming fabric is at the level of the outer surface 42 of the roll, so that the pulling forces act as far as possible in the central axis of the forming fabric, i.e. in the neutral fiber.

Fig. 10 shows further development designs of the weaving machine of fig. 1a and 1 b. The device 2 for feeding warp threads 4 comprises for each warp thread a package 42 from which the warp threads 4 are fed to rollers 46, 48 via a thread brake 44. From there the warp threads 4 run via two guide rods 50, 52 towards the opening device 6. The roller 48 is biased towards the warp threads 4 by means of a spring 54. Between the guide rods 50, 52 there is a lifting heddle 56 for each warp thread, the warp thread 4 extending through a heddle eyelet 58. The lifting heddles 56 are pretensioned downwards by means of springs 60 in order to compensate for shaking occurring during weaving between adjacent warp threads. At the upper end of the lifting heddle is positioned a contact rail 62 of a warp stop motion 64, which should be activated in the event of a warp thread break or an impermissible drop in the warp thread. In this respect it should also be pointed out. The relationship between the course of the warp threads through the guide rods 50, 52 and the warp stop motion contact rail 62 is not shown to the correct scale but rather is a schematic representation.

A guide roller 66 and a stretch roller 68 are disposed between the fabric support 22 and the fabric take-up mechanism 28 such that the forming fabric 26 between the fabric support 22 and the guide roller 66 is bowed downward by a small amount. The purpose of the press bending is to stretch the upper region of the profile on the fabric support 22 and on the guide rollers 66 and to stretch the lower region thereof in the region of the stretching rollers 68. This has a positive effect on the warp tension of the finished forming fabric. The fabric take-up unit 28 is associated with a receptacle 70 for receiving the finished forming fabric 26.

Fig. 11 shows a device 72 for feeding backing wires (filler)74 to a weaving machine. Such spacer filaments may have properties and dimensions that differ significantly from the remaining warp yarns. For example, the spacer wires may be made of plastic, steel wire or steel cable, or have a much larger cross-section than those of the warp yarns. For example, the spacer wire may be a tubular structure. Since the operation of the spacer wire 74 is more difficult than the other warp yarns 4, special measures are required for conveying it. The feeding device 72 for the spacer wire 74 first comprises a spacer wire reel 76, which is connected to a braking device 78. The backing wire 74 drawn from the backing wire reel 76 is guided to the opening device 6 via different guides 80, 82, 84. Between the guides 80 and 84, a tensioning device 86 is provided, which has a pivot lever 88, on which a clamping roller 90 is fastened, which clamping roller 90 is prestressed against the backing wire 74 by means of a spring 92. A contact 94 is assigned to the rocker 88, and if the spacer wire 74 breaks or the spacer wire pretensioning is not sufficiently strong, the rocker 88 comes to a stop against the contact 94.

With this weaving machine, different shaped fabrics, in particular ropes of different construction, can be produced. Such a weaving machine allows higher production speeds than a rope-weaving machine and allows the manufacture of ropes of large length.

Fig. 12 to 15 show a weaving machine according to a further modified embodiment of the invention with a pivotable cloth holder 22 d. In figure 12 the fabric support is in the normal or centered position and the warp yarns neither rise nor fall. In fig. 13, the fabric support in this loom is in a position corresponding to a "large rise". By "substantially raised" is meant herein that most of the warp yarns 4, typically more than 75%, are raised, while less than 25% of the warp yarns 4 are lowered, or that this core 96 is raised when a thicker and stiffer core 96 is used. In which case it is less dependent on the distribution of the other finer warp yarns 4. In fig. 14, the fabric support 22d in this loom is in a position corresponding to a "small rise". By "slightly raised" is meant herein that most of the warp yarns 4, typically more than 75%, are lowered, while less than 25% of the warp yarns 4 are raised, or that this core 96 is lowered when a thicker and stiffer core 96 is used. In which case it is still less dependent on the distribution of the other finer warp yarns 4. Fig. 15 shows the increase in the lifting and lowering range of the weaving machine according to fig. 12 compared to a weaving machine without the measures of the modified embodiment. The effect achieved in this embodiment is further improved in that, for this purpose, the fabric support 22d has, in the front molding zone, a circular molding-hole cross section 24d which, in the case of a circular rope, corresponds to the cross section of the rope, but which expands in the rear zone. In this case, the cross section of the rear bore expands elliptically upwards and downwards, and the expansion is formed by straight parallel flanks. This expansion inside the fabric support 22d is linear, i.e. the straight parallel sides constituting the expansion, increase from zero (front) to the full sides (rear) according to the embodiment shown in the figures herein. The rotary movement of the fabric support 22d is supported by this shaping. According to the exemplary embodiment shown in the figures, the pivotable fabric support 22d is freely pivotable about an axis 100 above the shaping opening 24d transversely to the weaving direction, with the result that the pivoting is limited by the shaping and the fabric (cord) passing through. Of course, the pivotable molding fabric support 22d should be positioned so as not to come into contact with the reed 21 before it is stopped at the fabric support 22d (in any of its pivoted positions) in any of the pivoted states. For the sake of illustration, it should be pointed out that the square profile section of the pivotable fabric support, i.e. in the case of square cables to be woven, the rear cross section is preferably rectangular.
