Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method for mounting a warp beam on a loom and passing the warp threads to a weaving device.

[Prior Art] A new warp beam (hereinafter referred to as A typical work procedure is adopted in which the warp threads are inserted into the dropper, heddle frame, and reed of the warp cut detection device before installing the full warp beam. To connect the warp end of the full warp beam to the cut end of the woven fabric on the loom side, multiple cuts are made in the warp direction at the cut end of the woven fabric, and the multiple cut pieces formed thereby There is a method of tying the tips of the warp threads together at an appropriate ratio. However, with this method, not only does it take a considerable amount of time to tie the warp threads and the cut pieces, but it also requires tying them parallel to the weaving width direction to balance the warp tension at each location in the weaving width direction. This is a task that requires extremely skill.

Therefore, Japanese Patent Publication No. 51-36828 and Japanese Unexamined Patent Publication No. 62
Japanese Patent Application No. 184150 discloses a method in which a coarse woven fabric is formed at the warp end of a full warp beam, and the coarse woven fabric is connected to a cut end of the woven fabric on the loom side. According to this method, the above problems can be solved to a considerable extent.

[Problems to be Solved by the Invention] However, coarse woven fabric has a rougher texture than normal woven fabric, and the coarse woven fabric passes between the surface roller and press roller that constitute the winding device of the loom. In this case, the coarse woven fabric is distorted due to the pulling action of both rollers, and the warp rows cannot be picked up uniformly. This causes problems such as poor formation of the woven fabric or warp breakage. or,
Although the connection between the cut end of the woven fabric on the loom side and the coarse woven fabric has become much easier than the direct connection between the cut end of the woven fabric and the warp threads, there are certain steps required to make this connection well. It is inevitable that it will take time.

The present invention aims to avoid these problems inherent in the use of coarse woven fabrics and to provide a method for looming that eliminates the need for connections to the cut edges of the fabric on the loom side.

[Means for Solving the Problems] To this end, in the present invention, the machine gear passes the warp threads of the full warp beam in the order of the warp cut detection device, the heald frame, and the reed before work, and A piece of woven fabric is fixed to the warp end of the warp, and the full warp beam and the warp threading member through which the warp threads have been passed are attached to the loom, and the woven fabric is attached to the take-up part of the winding device of the loom. Made it possible to connect pieces of cloth.

[Function] In the preparation stage before work, the machine is equipped with a warp cut detection device,
The warp threads of the full warp beam are passed through a warp passing member such as a heald frame or a reed, and pieces of woven fabric are fastened to the tips of the warp rows. Then, the full warp beam and the warp passing member through which the warp threads have been passed are attached to the loom, and the woven fabric piece is connected to the take-up section of the winding device, thereby completing the loom work. The method of connecting the woven fabric piece to the take-up part of the take-up device is easier than the connection to the cut end of the woven fabric on the loom side, and, unlike coarse woven fabric, there is the problem of tissue collapse due to the take-up action. do not have.

Supporting woven fabric piece w1
．． Even when w2 passes through the take-up area between the surface roller 42 and the press roller 43, the fabric pieces wl and w2, which have the same U-weave strength as the normal woven fabric W, do not undergo tissue collapse. As a result, uniform tension is applied to the warp yarns sandwiched between the upper and lower woven fabric pieces w1 and w2, and the surface fastener ω1. Due to the fine gripping action of ω2, the warp threads do not slip out from between the woven fabric pieces Wl and W2. Therefore, a good woven fabric is formed even during weaving when the woven fabric pieces Wt and w2 are being picked up. .

Woven fabric pieces wl, w2 that provide such good woven fabric formation
The work of directly inserting the tip of the cloth into the take-up area between the surface roller 42 and the press roller 43 is much simpler than the conventional work of connecting it to the cut end of the woven fabric on the take-up shaft, and requires less skill. A contact point for making the tension uniform in each part of the warp row in the width direction without requiring
ty% ill! Adjustment can be done with good precision.

Moreover, the woven fabric piece w1 peeled off from the 72nd row of warp threads Tl
, w2 are reusable and are advantageous in terms of cost compared to forming a woven fabric using conventional coarse woven fabric.

Note that the woven fabric piece w1. Although a rough texture is formed between the rear end of w2 and the woven fabric W, the tip of the woven fabric piece Wl and w2 is sandwiched between the surface roller 42 and the press roller 43 at the take-up site. In the state, the woven cloth pieces wl, w
The woven fabric piece Wl, so that the rear end of 2 is as close to the woven fabric as possible,
If the length of W2 is set, the woven fabric W and the woven fabric piece wl,
The length of coarse tissue growth between w2 and w2 can be made as short as possible.

Thereby, even when the rough texture passes through the take-up area between the surface roller 42 and the press roller 43, it is possible to avoid the texture collapse and prevent a partial quality deterioration of the formed woven fabric W.

Of course, the present invention is not limited to the above embodiments (
, for example, by attaching and connecting pieces of woven fabric to the tips of the T rows of warp threads using gummed tape, heat-sensitive tape, etc., or by sewing them together with a sewing machine, or by attaching - pieces of woven cloth only to one side of the row of warp threads. You can do it like this.

[Effects of the Invention] As described in detail above, the present invention attaches a piece of woven fabric to the tip of the warp line of a full warp beam attached to a loom, and then attaches the woven fabric to the take-up part of the winding device of the loom. Since the pieces of cloth are connected, it is very easy to apply tension uniformly to the warp, and the loom has the advantage of simplifying the work and contributing to the formation of a good woven fabric. It has a great effect.
