Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is characterized in that a twill winding plate having a core necessary for the woven cloth is placed on one side of a punchless loom, and the vertical striped yarn regularly wound on this weft winding plate is weft wound. The aim is to weave a clear and free wide, medium, and vertical pattern by dividing the front and back sides of the board into sea bream threads, feeding them to the warp threads.

In the conventional mochi weaving method, weft winding plates are attached to the cedar and the twill is supplied by the reciprocating movement of the cedar. Although this method is good for small and medium woven fabrics, It was impossible to weave Hironakamon because the Hai and Weft scroll boards would be the largest.

The present invention aims to provide an epoch-making method of weaving a rice cake pattern using a non-Azusa loom that eliminates the drawbacks of the conventional method.
The feature is that a weft winding board with a weft equivalent to the width of the woven cloth is installed on one side of the mumura loom, and the powder weft is wound in parallel in an orderly manner in the direction of the striped winding board. A pair of L-shaped control hooks are placed symmetrically on both sides of the twill winding board to unwind the threads in the correct order from the end, and the warp and weft yarns destined for one side of the front and back sides of the striped winding board are unwound in the following manner. and supply it.

Hereinafter, an example of implementing the method of the present invention will be explained based on the attached drawings.
I will explain in detail.

Reference numeral 1 denotes a weft-wound plate having a core necessary for the woven fabric, and vertically striped yarns 2 are wound in parallel in an orderly manner in the direction of the weft-wound plate.

The vertically striped yarn 2 is unraveled in an orderly manner from the winding end position, and the L-shaped control hooks 3 and 4 are located at symmetrical positions at both side edges of the winding plate at the winding end point. And each hook tip P
, P' are arranged in such a manner that they alternately come into contact with and leave the side edge green A and the mouth, and when the mochi weft 2 on one side of the striped winding plate 1 is scaled, the hook of the L-shaped control hook 3 Hang the mochi weft 2 on the tip P and make the vertical striped thread 2
When the L-shaped control hook 3 releases the vertically striped yarn 2, the warp and weft yarns 2 on the back side of the picture scroll plate are scaled, and the hook tip P' of the L-shaped control hook 4 controls unraveling. Moreover, when the L-shaped control hooks 4 release the warp and weft yarns 2, the spun yarns 2 on the surface of the weft winding plate are unraveled, and the operation of each of these L-shaped control hooks 3 and 4 is mechanical or electrical. This is repeated in synchronization with the operation of the thread guide ring, which will be described below. Reference numeral 5 denotes a thread guide ring which is moved back and forth at a position in front of the weft winding board 1 at a certain distance apart, with a vibration equal to or even larger than that in the twill winding board, and which acts both in the reciprocating action and in the above-mentioned two directions. The unraveling action is performed under constant synchronization of the contact and release actions of the L-shaped control hooks 3 and 4.

That is, when the hook tip P of the L-shaped control hook 3 is currently in contact with the side edge green A of the weft winding plate, the thread guide ring 5 is at position A on its extension line as shown by the solid line, and the hook is Since the vertical striped yarn 2 is held at the tip P, unraveling is not performed, but at the hook tip P
When the thread guide ring 5 separates from the side edge green A of the twill board, the thread guide ring 5 simultaneously moves toward position B on the other side as shown by the dotted line.
Due to this moving action, the spun yarn 2 is detached from the hook point P and pulled to the yarn guide ring 5, whereby the yarn is unraveled. During this operation, the hook tip P' on the side of the L-shaped control hook 4 is initially separated from the side edge green opening of the striped winding plate, but the L-shaped control hook 3
At the same time as the hook point P separates from the side edge green A of the twill winding board, the movement of the shell thread guide ring 5 starts and at the same time it comes into contact with the side edge green opening of the striped winding board. This is to ensure that the threads do not unravel more than the picture scroll board. The illustrated dotted line indicates this state. Next, when the hook tip P' of the L-shaped control hook 4 separates from the side end green opening of the winding plate, the thread guide ring 5 moves again toward position A, and due to this movement, the warp and weft yarns 2 are moved away from the hook. Destination P'
During this action, the hook tip P of the L-shaped control hook 3 is brought into contact with the side edge green A of the weft winding plate, and the spun yarn 2 is released from the striped winding plate. This is to prevent the threads from becoming unraveled more than medium.

In this embodiment, the vertically striped yarn 2 wound on the back side of the weft winding plate 1 is threaded by the movement of the yarn guide trench 5, that is, from the position A to the position B, and from the position B described later. In the movement toward position A, the vertical striped yarn 2 wound on the front side is unraveled, and by repeating the same operation, the vertical striped yarns on the front and back sides of the picture scroll are alternately separated by one length. The threads are unraveled.

Since the lengths of the vertical striped threads on one side of the woven fabric and the weft winding board are equal, the scarlet-patterned mochi weft on the board surface is divided into sections for each weaving area, unraveled accurately, and fed between the warp threads. As a result, accurate and clear textiles can be woven.

Reference numeral 6 denotes a fixed ring fixed on the center bisector of the weft winding plate 1 and at a position in front of the thread guide ring 5, and is fixed to the center bisector of the weft winding plate 1 and in front of the thread guide ring 5, and
The starting end serves as a guide for the weft thread pulling action by a rapier rod (not shown), which serves to keep the thread length and tension constant, and to facilitate introduction into the warp threads 7.

Note that when the rapier rod grips the unraveled scarlet twill yarn 2 and inserts it from the fabric selvage 8 position to the woven fabric selvage 9 position, although not shown in the drawing, the cutting blade performs cutting on the woven fabric selvage 8 side. The cutting thread end on the fixed ring side is gripped by suitable gripping means in preparation for gripping the rapier rod which is subsequently introduced.

In carrying out the present invention, any suitable means may be employed for reciprocating the thread guide ring, but generally mechanical means such as ladder bars or rails are employed.

In addition, the emaki board 1 is made to move slowly in the direction of the arrow F in order to smoothly thread the scales of a certain length up to the winding start thread in the positioning layer of the L-shaped control hooks 3 and 4. For this purpose, mechanical means using a screw is generally used and preferably employed. By implementing the present invention as described above, it is possible to accurately and clearly weave the desired free Hironaka-hi, which has been a dream of the industry since ancient times, and it is also revolutionary in that it dramatically improves weaving efficiency. This is a great method.
