Warp self-threading device and method thereof

Abstract

This invention relates to a drawing-in device and method thereof in the preparatory process before a loom weaving. The warp self-threading device for threading warp being prepared for loom-weaving through heald wire includes: a warp feeding device, which supplies yarns to multiple cones by means of winding yarns on the cones; a shift device, which can shift varieties of wires to the heald wire cheese; a loom structure corresponding to the looming, which choice the optimal seed wires automatically, can rapidly go on the processing operation after the yarn connection. Therefore, the confirmed operation of weaving tissue can be eliminated or simplified in the next step, the looming process can be promoted and the operator's burden is lightened.

Description

technical field [0001] The invention relates to a warp threading machine device and a method thereof in the pre-weaving preparation process of a loom, in particular to an automatic warp thread threading device composed of heddles that separate the warp thread to form a shed through the warp thread to be used for weaving, and Automatic threading method for warps. Background technique [0002] In the preparation process before weaving on the loom, the warp thread (or seed thread) used for weaving must be passed through the dropper for detecting warp thread breakage, the heddle for separating the warp thread to form a shed, and the reed for arranging the warp thread these jobs. In the past, these operations were carried out by each machine through three operations (that is, the warp thread passed through the drop wire, heddle and reed), but in recent years, a machine (warp drawing-in machine) has been developed to perform the above three operations. working device.

AI Technical Summary

Problems solved by technology

[0010] Thus, including the warp thread automatic introduction device described in Patent Document 1, in the conventional drawing-in machine, the warp thread that is actually woven into the weaving structure is passed through a single type of warp thread, heddle wire, and reed. During the yarn splicing operation where the end of the thread is knotted, and after the operation, it is difficult to distinguish which kind of thread corresponds to which warp thread at a glance

As a result, in the subsequent weaving process, until the weaving thread is actually inserted into the cloth, the weaving error cannot be found, which will cause a lot of time loss and loss of related materials such as warp thread and weft thread.

Moreover, when a single seed thread and warp thread are knotted, the twist direction and thickness of the warp thread are different, and the reverse twist of the seed thread will loosen, or the knot will not be tight.

As a result, warp threads become entangled, thread ends loosen, and processing after yarn joining is delayed.

[0011] At present, due to insufficient countermeasures in the preparation process for weaving, there may be adverse effects on the processing work after yarn connection and weaving operations, and no device or method to solve such problems has been developed so far.
