Abstract

A process is for manufacturing epingle material on a loom and involves using a rapier loom (1) to produce a fabric (6) with a base weft and bound pile yarns (11). The pile yarns (11) are laid across auxiliary picks (9) located above the fabric (6) and drawn laterally out of the pile loops (15) to produce the epingle product.

Description

Technical field

The invention relates to a method of producing epingle fabric on a weaving machine, in particular to a method of producing epingle fabric which is suitable as a upholstery fabric, for example for furniture, vehicles and seats in vehicles.

BACKGROUND OF THE INVENTION

The epingle fabric is a warp velvet or aksamiet with uncut hair loops. It is known that these fabrics are produced on special weaving machines in which the hair loops are laid by means of backward moving rods. However, epingle weaving machines have high purchase costs and cannot work too fast, since the rebound rods become hot by friction as the weaving machine operates. The higher the working speed of the weaving machine, the more the rebound rods will heat up and their temperature can reach such a height that there is a risk of tanning or even ignition of the fabric. In addition, the density of the wefts and thus the softness of the fabric is limited by the diameter of the rods, which cannot fall below a certain lower limit.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a process for producing epingle fabric, in particular epingle fabric as a coating material, which is simple and inexpensive.

SUMMARY OF THE INVENTION

The object of the present invention is to provide an epingle fabric according to the present invention, wherein the fabric is produced on a dowel weaving machine, producing a fabric with a base weft yarn and interwoven pile yarns, and pile yarns being laid by auxiliary weft yarns above the fabric. in order to make the epingle fabric, the weft yarn is pulled out laterally from the hair loops or loops.

Preferred embodiments are set forth in the subclaims.

According to the invention, the epingle fabric is produced without the use of metal bars on a pin weaving machine, wherein a pair of pegs insert the base attack and the pile thread of the fabric into the warp threads of the fabric. loop fabric epinglé. The auxiliary attack is ligated through special auxiliary edges located at the edges of the fabric and is pulled out through these auxiliary edges before the fabric is finished.

In order for the auxiliary attack or auxiliary wefts to be withdrawn from the finished fabric, the weft threads are cut between their outer ends, for example roughly in the middle of the fabric, and for example by guiding the finished fabric over a fixed knife that cuts the auxiliary weft threads. it does not damage other parts of the fabric. The auxiliary edges, to which the auxiliary wefts are firmly bound, are then removed from the epingle fabric, for example by means of a needle roller, by means of which the separate auxiliary wefts are pulled from the pile or loop of the epingle fabric. The auxiliary edges are then rolled, for example, with the auxiliary weft portions hung thereon and handed over for further processing.

With the solution according to the invention, it is possible to produce epingle fabric on double-pin weaving machines as a double-ply fabric, therefore no special machine is needed for weaving this fabric, namely machines with re-moving steel rods. Therefore, the high purchase costs of special epingle fabric manufacturing machines can be saved. Since the loops or loops of the epingle fabric are not formed by means of backward moving rods which become hot during operation, but are formed by layering by means of auxiliary wefts, the risk of heating or overheating of the fabric is avoided. Furthermore, since the auxiliary wefts are threads having a very small diameter, much smaller than the steel rods of known weaving machines for producing epingle fabric, a higher yarn density can be achieved and thus a thicker and therefore finer epingle fabric can be produced.

Since there is no risk of overheating of the epingle fabric using the method of the invention, the pin weaving machines used to carry out the method of the invention can operate at operating speeds much higher than the known epingle weaving machines, so more time can be produced over a period of time epinglé fabrics than on special weaving machines for epinglé fabrics. As a result, the production costs are reduced, while at the same time a better quality is made possible by a higher thread density.

In the process of producing the epingle fabric according to the invention, waste is produced since the auxiliary edges together with the auxiliary wefts have to be removed after the fabric has been finished, but the material of the auxiliary edges and auxiliary wefts can be reused, for example it can be further processed into new textile material. The use of auxiliary wefts and auxiliary edges, which need to be removed after the fabric is finished, is generally cheaper than the production of epingle fabric on known weaving machines with rods.

BRIEF DESCRIPTION OF THE DRAWINGS

BRIEF DESCRIPTION OF THE DRAWINGS The invention will now be explained in more detail with reference to the accompanying drawing, in which: FIG. 1 is a vertical cross-sectional view of the epingle fabric in its manufacture on a pin weaving machine; and FIG. 2 is a top view of the top side of the fabric produced in FIG. 1, from which it is apparent how the auxiliary wefts of the finished epingle fabric are pulled to one side to form the hair loops or loops of the fabric, the other side not shown.

Examples

In FIG. 1 shows how, on a pin weaving machine 7 with double-edged pointed knives 2 for the production of double plush, warp yarns 3 and 4 are produced from warp threads 5 and under weft yarns 5 underneath double-edged pointed knives 2. handles or loops 15 which extend above the upper side of the double-edged pointed knives 2. '

The loops or loops 15 of the pile yarn 11 are formed by means of auxiliary weft yarns 9+ which are inserted above the double-edged pointed knives 2 by a separate pair of pegs of a used pin weaving machine 7 with two pairs of pegs.

To hold the auxiliary weft yarns 9, epi-fabric auxiliary edges 16 of the other weft yarns 10 and 8 are weaved above the double-edged pointed knives 2, and the weft yarns 17 of which are shown in FIG. 2, only one auxiliary edge 16 is shown on one side of the epingle fabric 17.

In FIG. 2, it is shown that the auxiliary weft threads 9 are woven into the auxiliary edges 16 and in the area of the loops or loops 15 formed by the pile threads 11, these auxiliary weft threads 9 run once inside the loops or loops 15 and once above the pile yarn 11 therefore, only every second attack is required to form the loops or loops 15.

The epingle fabric 17 passes inside the pin weaving machine 7 along the double-edged pointed knives 2 in the direction of the arrow 13 and encounters a rigid knife 14 which, by means of the weft thread 9, roughly cuts the other over the double-edged pointed knives 2. threads fabric 17 epinglé. Thereafter, the auxiliary edges 16 are removed from the epingle fabric 17 to the sides as shown in FIG. 2, whereby the slit weft threads 9 are pulled out of the epingle fabric 17 to one side and the other and thereby separated from the epingle fabric 17. The finished epingle fabric 17 then has, as shown at the right end of FIG. 1, sliced loops or loops 15 that are typical of epingle fabric.

The auxiliary edges 16, together with the ends of the auxiliary weft threads 9 which are firmly, tied into them, can be twisted or otherwise folded and then used for further processing. Since the auxiliary weft threads are firmly bound to the woven auxiliary edges 16 due to the weaving technology used, there are no remnants of the auxiliary weft threads left in the epingle fabric 17 or in its loops or loops 15, respectively.

With the method according to the invention, it is possible, as mentioned above, to produce epingle fabric 17 even on dowel-type weaving machines, and a higher yarn density can be achieved because the spacing of successive loops or loops 15 of epingle fabric 17 is not limited by rods. made of metal such as steel.
