(54) METHOD FOR OBTAINING CORD-LIKE PRODUCTS

one

The invention relates to the field of basic technology manufacturing and concerns a method for producing cord-like articles such as bands, laces, knitted elastomeric yarns, the latter of which in turn can be used in other products (elastic bandages, corsets, dressings) laces. filler in the form of weft yarn, etc.

The most productive is in the hall way of producing cord-like products of a certain range.

There is a known method for producing cord-like products (shoelaces), in which, on a one- or two-foundation base, there is a looping hinge bar, which serves as shoelaces. When indent, the adjacent laces are not connected to one another and are sent to the machine's pull mechanism as separate streams. However, when inserted as separate laces not connected to one another, it is very difficult to produce the same mechanical pull of all the laces. Provide a sectional pull mechanism (the number of laces is equal to the number of

sections, having an autonomous drive for each section) is practically not possible, since the string has a small width Ull.

Also known is a method of producing cord-like products, which consists in the fact that several products are simultaneously harvested in the founding machine at the same time, and in the process they are busy

10 transverse yarns, thus obtaining the web, and after finishing the web formation, the transverse yarns are removed to separate the products, while the products are arranged in columns

15 single chains of inelastic raw materials and a longitudinal weft thread of elastomeric raw materials (polyurethane thread with the brand name lycra) is inserted into each column of the chain. Thus, elastomeric yarns are wound around 20, and then used as a raw material for occupying knitwear products or for weavers (medical bandages, squeezing mesh dressings, such as swimwear, swimsuits, etc.). This method is much more productive than the one previously described and provides a reliable, uniform for all products.

drawing, as in the process of understating, it acts on the canvas and not on the individual columns of the chains. The production of products in the form of several relatively wide streams also makes it possible to use sectional mechanism of extension 2.

However, when removing the transverse threads, it is possible that the individual threads in the chains become entangled and tangled, as it is very difficult to grab each end of the transverse thread when pulled out. Transverse NTs may go to waste, since they will be relatively short lengths. The reliability of removal of all transverse threads will decrease and the removal process itself afterwards will in turn reduce the productivity of the process. If, however, we use soluble threads, for example, in water, as transverse threads, this will thereby completely eliminate any indirect possibility of their reuse.

This method, in the majority of cases, coincides with the technological principles of the PIM and the achieved result is taken as a prototype.

The aim of the invention is to increase productivity.

This goal is achieved by the fact that in the method of producing cord-like products, at the same time at least one auxiliary column is harvested, in the loops of which cross threads are fixed, which are then cut, and the cross threads are removed from the web by disconnecting the auxiliary column. with pieces of transverse threads from products.

Possible and preferred are the following embodiments of the method. Products in the form of single chains, and an auxiliary column in the form of a double chain.

Products and an auxiliary column in a creeper in the form of single chains.

Products and an auxiliary column in the zhut in the form of double chains.

The products were made in the form of double chains, and the auxiliary column - in the form of a single chain.

Products are woven on a flat dvufontarii basics by a damming machine, with the cross threads being laid on both phonographs of the machine with a spiral weft, and an auxiliary column in the middle of the canvas.

The production of products is carried out on a flat two-foundation base by a filling machine, whereby each received part of the web is connected by an auxiliary column on one side. The manufacture of products is carried out on a bifurcation basis with a filling machine, with each piece of fabric obtained connecting with the appropriate

an auxiliary column in the middle of each part of the canvas.

As transverse yarns and yarns of the auxiliary column, those rmoplastic yarns are used which are fused prior to removal from the web.

Auxiliary column in a row of several interconnected hinge columns.

Each product is composed of several mutually connected hinge columns.

Claims (9)

On a double-base warping machine, the needles 1 of the back of the pattern and the needles 2 of the front are in the harness 3 and are connected with a cross-thread 4, which is inserted into the auxiliary bar 5, which has a double chain. After that, either directly on a rashel machine, which is more preferable, or on a special machine, transverse threads are cut at the places indicated by arrows (Fig. 1B). A column 5 is pulled out with 4 of them and they release the product 3, which is wound in packages in a known manner (Fig. 1c). According to FIG. 2, the method is carried out in the same manner; FIG. 1, but the threads 4 do not transfer from the needles of one fountain to the needles of another (Fig. 2A). After finishing the blade, the web is removed from the needles; 2B and cross the threads from the edges, then a column b with threads 4 of the articles 3 is pulled. FIG. 3 shows two tubes connected by a jumper a, e, h. This is a semi-finished product, corresponding to the method of FIG. 1. Sections “a, 6 6,1 on both sides denote sections of the transverse thread 4 from the needles of the back footprint to the needles of the front, and section 3.6,., 2 is a double chain of the auxiliary column 5.. This option is very convenient for cutting, since the jumper points, 5, ft, o. the transverse yarns 4 are not interwoven with other threads and tensioned, which allows them to be cut directly on the sewing machine. FIG. 4.5, the areas designated by letters have the same designations as in FIG. 3. FIG. 4, 5 correspond to the method of FIG. 2. In FIG. (b) The tube in which item 3, shown on the needles of both machine fountains, is connected by a cross thread 4, laid in a spiral, is shown. This option is most preferred in conjunction with the option of FIG. 1, since the removal of the cross thread 4 is carried out without difficulty (the thread 4 does not surround the loops and bends in the columns of the articles 3). According to FIG. 7 yarns 4 are laid in each tube 6, 7 and both ducks can be laid in a spiral, as well as with any other known option of laying weft yarns. Laying the weft threads 4 is most preferable in view of free weft fixing in the loops of the products 3, which further makes it possible to easily stretch the transverse threads 4 from the product 3. For this, it is advisable to use threads having a coefficient of friction greater than friction coefficient of yarns used as transverse yarns 4. Thermoplastic yarns, for example, nylon, can be used to improve the strength of the joint of the auxiliary column 5 q yarns 4 and to melt them. FIG. 8 and 9 dots are marked with needles of one phonture, crosses of the other (. Front and back). as additional weft threads 8, you can use the threads lycra, virin, interest, and for banding is-g. use cotton yarn, natural silk, viscose, acetate, polyamide, polyester and other threads. The recycling of elastic yarns causes certain difficulties and therefore the use of an auxiliary column simplifies the process of separation of products. Production technology for FIG. 13-22 does not differ essentially from what was previously described, with the exception of the following features. FIG. 1 and 2, position 3 denotes single chains, 5 indicates a double chain, and in FIG. 13 and 14, position 9 are double chains, positions 4.5 and the same as in FIG. 1 and 2. In FIG. 15 transverse threads 4 are invoked on only one fountain. FIG. 17, auxiliary column 10 is a single chain column. FIG. 20, the auxiliary column consists of several looped columns of the chains 10. FIG. 21 shows a scheme for the production of products on a single-line bridge. FIG. 22 - to the knowledge on a dual-circuit machine. It is important to note that the resulting auxiliary columns 5 with yarns 4 can in turn be used as pile threads for working with any articles. X1 each item 3 does not necessarily have to be strings of chains. This kyugut be products consisting of two, three or more hinge columns, both single and 7. The proposed method has high performance, allows the use of well-known bases, provides reliable connection of products, and removes waste. The use of one double-bottom achel machine with 900 needles per each fountain allows up to 1,800 pieces of products to be received at the same time. Of course, the structure of the sheath of elastomeric yarns differs from woven bogs, but the tied up elastomeric ITIs also have a great use, especially for the production of medical buildings, and an MDF type foot bedding machine can be used as a specific thread.
