The present invention provides a method and apparatus for supplying yarns of a textile material for supplying a group of parallel yarns to an apparatus for manufacturing a two-dimensional fiber fabric at a working position of the manufacturing apparatus, and an apparatus and method for manufacturing such textile material. It is about. Hereinafter, the two-dimensional textile fabric manufacturing apparatus is referred to as "final fabric manufacturing apparatus", in particular the apparatus may be a loom, warp knitting machine, or a device for processing a group of parallel yarns.

The textile material for supplying the first group of parallel yarns is described in Korean Patent Application No. 81-821, which is a prior application, and the present invention relates to the application.

The concept of "sa" here includes not only elastic materials, but also monofiles, spun yarns, twines, ribbons, etc. The concept of "two dimensional fabrics" refers to woven and knitted fabrics, hose fabrics and Nets and the like. The knitted fabric can be made in a warp knitting machine or a corresponding crocheting machine.

It is known to feed a set of parallel yarns to the final fabric maker using warp beams. Existing textile materials for feeding a set of parallel yarns include rolls of yarns placed on warp beams, the use of which is accompanied by a number of disadvantages.

As soon as the warp beam is consumed, the beam must be replaced with three, with the warp beams of the empty warp beams and the warp beams of the new warp beams connected to each other with the end product manufacturer stopped. This reduces the efficiency of the final product maker therein.

When the slopes are released from the slope beam into small rolls, the angle at which the slopes pass through the guide member, ie the back rail, changes. Thus, when the warp beam decreases, the tension of the yarn changes. Also, in order to compensate for the change in tension, a significant cost mechanical or electrical device may be needed. Inclined beams also require storage and transportation costs.

It is also known to supply a group of parallel yarns to the final fabric manufacturer directly from the bobbin krill, i.e., the frame holding a number of bobbins, which requires a lot of space and a lot of investment cost. It requires a mounting device and a brake. In addition, various guide means are required for each of the yarns supplied from the bobbin. In addition, the bobbin itself requires transportation and storage costs.

Accordingly, it is an object of the present invention to supply a group of parallel yarns without requiring the installation of bobbin krill or warp beams in front of the final fabric making machine.

The fabric is composed of a low water intake fabric, hereinafter referred to as "coarse fabric". The uptake should be shown in relation to the final fabric to be made from the coarse fabric. In the extreme case, when the final fabric is a fabric with 200 weft loops per cm, a fabric with 20 weft loops per cm may be called a coarse weave. In most cases, however, the coarse woven fabric has a very low uptake. Weft loops should be weaved to allow them to be removed as successive wefts in subsequent steps.

In this way, the removal can be performed efficiently, and the weft can be reused. The same applies to the case of two weft yarns inserted in both directions. When the weft is removed, a group of parallel yarns remains, which can be fed directly to one or several operating positions of the final fabric maker.

Therefore, it is not necessary to use the tilt beam. The sparse fabric can be stored simply by running it sequentially or arbitrarily in a reservoir, in particular a container. The reservoir may hold several tons of coarse fabric and thus replace several warp beam rolls. The coarse fabric can be transported at minimal cost. Foldable containers, card board boxes, temporary containers, etc., which do not require the use of bobbins or similar members and take up little space during transport, can be used.

At the place of manufacture of the final fabric, the reservoir may be placed away from the final fabric manufacturer and / or the machine making the coarse fabric, for example in a separate storage compartment. The sparse fabric can be conveyed over a long distance from the sparse fabric manufacturing apparatus to the reservoir by the guide mechanism and from the reservoir to the final fabric making apparatus. The sparse textile material does not have to be manufactured in a factory for producing the final fabric, but can be supplied to the factory by, for example, a folding container. In most applications, the coarse woven fabric has a smaller number of weft loops than the weft loops per cm, in particular less than the weft loops per 10 cm fabric length.

The coarse woven fabric can be made using a single weft yarn, and two weft yarns inserted from both directions may be used. In the latter case two inserters insert the weft loop into one opening. This process is particularly suitable for producing more coarse fabrics.

The closed ends of the weft loops may also protrude to the side of the coarse fabric. The use of coarse yarn may also make the fabric sufficiently resistant.

In the case of weaving a group of smooth yarns or in particular when low water intake is required, the coarse woven fabric can be fixed by a row of uncoilable stitches. In the treatment of the coarse fabric, the squelches open as the weft loops are removed, even if there are one row of squelch per edge.

The rows of squelches can be formed by the weft loops themselves, ie by using only weft yarns or by using auxiliary yarns. In the case of using an auxiliary yarn, it is necessary to remove not only the weft but also the auxiliary yarn in use.

The present invention relates to a method of supplying a group of yarns of coarse fabric at the working position of the final fabric manufacturing apparatus, wherein the coarse fabric is first supplied to the braking device accordingly, and thus the fabric and subsequent steps The yarns loosened from the fabric can then be held under tension between the braking system and the final fabric maker.

The weft or weft yarns are removed from the side (s) of the fabric in the tensioned state and wound on the bobbin. Subsequently, the grouped yarns will be supplied as a whole to the working position of the final fabric maker. Alternatively, a group of companies may be divided and supplied to various working positions. Conversely, especially if the final fabric is wide enough to require 4,000 heel slopes, fabrics produced with only 500 heel slopes may be supplied to a single working site in groups.

In addition, fabrics composed of yarns of different properties can also be used to make a final fabric of various yarns of different properties, such as dyeing, shrinkage, feel and the like.

If the coarse fabric is manufactured to have one or two rows of squelch that can be opened, care must be taken in the direction in which the fabric is fed, since the rows of squelch can only be released in the opposite direction of manufacture. .

It is also possible to provide the fabric as a processed fabric, which allows the end fabric manufacturer to carry out processing processes such as dyeing, shrinking or heat setting for small quantities of yarn. Portions of the fabrics can be dyed in different colors in the longitudinal direction, thus making it possible to produce a final fabric with cross stripes.

When the warp beam is consumed, the final fabric maker must be stopped so that the divisions of the blank warp beam and the new warp beam can connect the divisions together. However, according to the invention it is also possible to connect the fabric from one reservoir, for example from one vessel, with the fabric from another reservoir while the final fabric maker is in operation. Thus, the joining operation can be performed without stopping the final fabric maker. When the fabric in one reservoir is consumed, the new fabric in the next reservoir and associated with the fabric can be supplied to the manufacturer without interruption.

According to the present invention, the coarse fabric is also tensioned and released. The "braking device" described in the text includes a drive device that is not accelerated even by the pull caused by the final fabric maker.

The weft loop holder may be associated with each weft loop insert so that the retainer is placed at the exit point of the weft needle when the weft needle passes through the opening. When the fabric to be produced is very coarse, it is convenient to at least temporarily hold the closed end of the weft loop outside the edge. In its simplest form, the weft loop holder may be a mandrel reciprocating transversely with respect to the plane of the weft loop, or it may be a needle when making a product having a single row of squelch.

The lower the number of uptakes, the cheaper the production of coarse woven fabrics having one or two rows of squelch. At very low gas intake, the length per double weft running when the final fabric is pulled is significantly longer than the length of the knitting needle running back and forth around the double weft, which makes it difficult to form loops. According to the present invention, additional components such as deflection bars and weft retainers result in satisfactory operation of the loom for producing sparse weave fabrics even at very low water intake. Disadvantages will also be eliminated.

Further, according to the present invention, the coarse woven fabric can be made from yarns wound on bobbins, and thus the bobbins can be installed on bobbin krill.

However, the coarse woven fabric may be produced immediately after a weaving machine or a yarn treatment machine (for example, a combustor, a drawing machine or a finishing machine). When only some of the yarns required by a given machine are being processed, several machines that are driven simultaneously can be used simultaneously. Thus, the fabric may be supplied instead of the bobbin.

Hereinafter, embodiments of the present invention will be described in more detail with reference to the accompanying drawings. The coarse woven fabric is woven in a loom described below. In the simplest case, the warp to be woven is supplied from individual bobbins, which can for example be installed on bobbin cream. Thus, the coarse woven fabric can be produced in the same place as the place of making the final fabric. Further, when a yarn maker or yarn processor or elastic yarn is required, the fabric material may be woven from yarns supplied in a rubber yarn coater. When a textile material having a larger number of warp than one of the aforementioned machines can supply, it is also possible to drive several such machines simultaneously to supply the required warp simultaneously. The coarse fabric is stored regularly or irregularly in a reservoir, in particular a container. The container may be supplied from the place of manufacture of the fabric material to the place of final fabric manufacture. It is also possible to place at least one loom for producing the coarse woven fabric in the final fabrication site, where the loom manufactures the fabric from the bobbins and is permanently placed in the final fabrication site. Will be stored in wealth. The reservoir may be disposed at a significant distance from the fabric maker and the final fabric maker, and the fabric may be fed through the guide into the reservoir and from the reservoir to the final fabric maker. If several reservoirs are filled one by one, there is no need to interrupt the supply of fabric. When the end of the finally produced fabric is taken out of the last filled reservoir and fed to the final fabric maker, the fabric can be processed continuously from both the reservoir without interruption and without connections.

1 and 2 are shown in various ways to produce a coarse fabric in accordance with known processes. In FIG. 1, the weft loop 3 is inserted from the left into the group 1 warp 1 in such a way that the closed end 3.1 of the weft loops protrudes to the right by 1-2 cm. If coarse yarns are used, the coarse fabric is secured sufficiently to prevent it from being accidentally loosened. This method is suitable for fabrics that have a weft water number of at least one weft loop per 1 cm fabric length.

The method according to FIG. 2 is suitable in order to have a low water intake or as low as possible in weft loops per 10 cm fabric length. That is, according to FIG. 2, the coarse woven fabric has a single row of squelches 7 formed by the weft yarn 9 using the knitting needle 11. If manufactured to have very low gastric water, this method can be carried out on both sides. In this case, the weft loops inserted from the right side to the left side can be fixed by the squelch of the second row on the left side, and the squelch row can be loosened together with the weft loops 3. When the knitting needle 11 of FIG. 2 is removed, the upper weft loop 3 can be pulled to the left to release it. Next, the next loop can be solved below it. As such, the unwinding process should begin at the end of the last woven.

5 is arranged between the storage of the coarse fabric and the working position of the final fabric making machine, on the one hand to tension the supplied warp yarn 1 and to remove the weft yarn on the other hand. It shows an apparatus to make. In FIG. 5, the device is shown for use in this embodiment in FIG. 2, which is adapted to weave a row of squelch 7 using a weft yarn 2. FIG. Initially, the coarse fabric 17 is provided with a braking device having braking rollers 31 and 32 and an auxiliary roller 33 for pressing the coarse fabric against the two rollers. Supplied. The inclinations are pulled in the direction of the arrow 50 from the working position of the final fabric maker so that the inclinations can be kept in tension between the working position and the braking device.

The coarse woven fabric is guided through a round fixing rod 35 after passing through the braking system, and immediately after that the weft yarn 2 is removed forward as shown in FIG. 5, so that the rows of squelch 7 are released. do.

The weft yarn 2 is guided to the known doctor feeder 57 through the yarn guide 55, the yarn feeder 57 acts to pull the weft yarn at a constant speed. The pulling speed is selected according to the length of the weft loop 3 to be removed and the length of the squelch 58 formed therein and the rotational speeds of the rollers 31 and 32. The removed weft 2 is wound around the bobbin 60 and can be reused so that no cost increase is caused.

The sparse fabrics stored in the two storage containers 61 and 62 are connected to each other with their warp yarns, which can be done while the sparse material is supplied from the reservoir to the final fabric maker. If the coarse fabric has one or two rows of squelches, the joining is carried out as follows. That is, the coarse woven fabric is stored in such a way that not only its final ends 17e and 17e 'but also the first ends 17a and 17a' remain accessible from the outside. The final end 17e of the sparse weave stored in the reservoir 61 is supplied to the braking device 30 according to FIG. The first end 17a and the last end 17e 'of the coarse woven fabric are connected to each other by the inclination and the inclination, the weft and the weft, or the connection between the auxiliary and the auxiliary yarn. When the reservoir 61 is emptied, the end 17e 'is fed after the end 17a, and then the reservoir 62 is emptied, and the connecting ends 63 of the warp yarns of the coarse fabric are finished. Will pass. The final fabric with such connecting ends may be cut to length in subsequent steps if desired. Empty reservoirs may be replaced with new ones or the fabric may be resupplied from a sparse fabric maker.

7 to 9 show each embodiment of the working position 64 of the final fabric making machine. In the embodiment of FIG. 7, the coarse fabric 17 is fed from the reservoir 61, 62 or three or more reservoirs via the dismantling device 27 to the working position 64. The braking device 30 disposed in front of the dismantling device 27 is not shown in FIGS. 7 to 9.

In the case of the embodiment of FIG. 8, the coarse woven fabric 17 is supplied to the dismantling device 27 from two reservoirs 61, 62 as in the above embodiment. However, one group of yarns supplied by this apparatus is divided into three subgroups 1a, 1b and 1c, each of which is divided into working positions 64a, 64b and 64c. Supplied.

In the case of the embodiment of Fig. 9, the supplied loosely-woven fabric has various properties. That is, the reservoirs 61 and 62 are housed in the fabric material 17a having predetermined characteristics, and the reservoirs 65 and 66 are housed in the fabric material 17b having characteristics different from the above. The properties can be differences in dyeability, elongation at break, especially inclined shrinkage. The fabric material 17a enters the dismantling device 27a, the fabric material 17b enters the dismantling device 27b, and a group of yarns 1b from the device 27b are brought to the working position 64. Supplied. On the other hand, the group of yarns from the dismantling device 27a is divided into two groups of yarns 1a 1 and 1a 2, and the two subgroups are sides of the woven or knitted fabric manufactured at the working position 64. Forming warps for the tissue, this configuration is important when manufacturing automobile seat belts having tubular modulating weaves, the yarns of which are intended to have greater shrinkage than the center warps.

Similarly, work location 64 may be supplied with various groups of yarns from various coarse woven fabrics, thus for example fabrics having longitudinal stripes of various colors.

3 and 4, 10 and 11 illustrate a process of producing a coarse woven fabric material with a relatively narrow width produced in a needle ribbon loom, wherein the warp group 1 is a yarn treatment machine or The needle ribbon loom is fed from the bobbin krill. The loom consists of a weft insertion needle 70, a knitting needle 11, and a body 74. The knitting needle 11 is movable in the longitudinal direction of the ribbon between the two end positions shown in FIGS. 10 and 11. Close to the working path of the knitting needle, i.e., directly behind the body needle position 77 of the body 74, a deflection rod 76 in the form of a ceramic cylinder is disposed perpendicular to the ribbon surface.

Also, on the side of the fabric path on the opposite side of the knitting needle, an angled weft retainer 78 (FIG. 4) is rotatably installed about a horizontal axis, which is called a "stitcher." Will be. 4 shows two distal positions of the retainer 78. A small diameter portion 83 is formed under the ball-shaped end portion 82 of the retainer to guide the weft yarn 2.

In the position of FIG. 10, the weft yarn 2.1 passes around the small diameter portion of the weft retainer 78 in the upper position, and the weft insertion needle 70 inserts the weft loop 3 to the right, and the knitting needle 11 The head 11. 1) starts to move in the direction of the arrows 85 and 86 with the weft portion 2.2 hanging, wherein the bed of the knitting needle 11 is formed in the step of forming the squelch just before. We will have a weft loop (3.2). As the coarsely woven fabric 17 is pulled, the knitting needle moves to its final position as shown in FIG. 11, whereby a squelch is formed from the immediately formed loop 3. 2 and the weft loop 3 A new loop 3.3 is formed which is an extension of. The loop 3.3 is pulled back by the deflection rod 76 in the direction of the arrow 85 by the head 11. 1 of the biasing needle 11. Thereafter, the weft retainer 78 moves downward, releasing the weft yarn 2.1, thereby forming a temporary loose loop 92 in the fabric. Subsequently, the body needles and openings of the body are switched, followed by the cycle, and thus the loops 92 are pulled by the fabric pulling force.

Inserting the weft loops produces a coarse woven fabric in a wider state. In this case, however, the insertion needle 70 shown in Figs. 10 and 11 must be replaced by another known mechanism.
