Weaving bar preventing method of loom and apparatus for the same

Abstract

The invention discloses a weaving bar preventing method of a loom and an apparatus for the same. The weaving bar preventing technology, in which, when a loom is started, a cloth-fell displacing member that contributes to moving of a cloth fell of a cloth is driven to move the cloth fell towards a warp let-off side is provided. The weaving bar preventing method of a loom includes the steps: movement amount related information is previously stored in the loom, the movement amount related information being information for determining a movement amount of the cloth fell, the movement amount related information being determined such that, in a set range that has been preset and that is related to a winding diameter of a warp wound around a warp beam, the smaller the winding diameter, the larger the movement amount; and, when the winding diameter for a point in time the loom is started is included in the set range, the cloth-fell displacing member is driven on the basis of the winding diameter for the point in time and the movement amount related information. The weaving bar preventing method of a loom and the apparatus for the same can effectively prevent occurrence of weaving bar (stop segment) following stopping of the loom during the whole weaving period.

Description

technical field [0001] The present invention relates to a crosspiece preventing method and device for moving the fell of a weaving cloth toward the warp delivery side when a loom is started. Background technique [0002] When the loom stops due to poor weft insertion, etc., during the stop of the loom, the warp gradually elongates over time due to the influence of tension or self-weight, etc. sideways movement. And, when weaving is started (restarted) in a state where the cloth fell is moved in this way, a ledge (that is, a so-called stopper) will appear on the woven fabric. Therefore, in the prior art, in order to prevent such a rung (stop), before weaving starts, the cloth fall is corrected in advance by moving the cloth fall to the warp delivery side, thereby seeking to prevent the occurrence of the rung. files. In addition, the cloth fell movement (correction) is realized by driving the cloth fell position displacing parts on the loom that contribute to the cloth fell...

AI Technical Summary

Problems solved by technology

[0011] However, in the prior art described above, only the case where the amount of recoil is constant is considered as far as the recoil action is concerned.

Therefore, in this prior art, as the cloth fell movement amount differs due to the change of the roll diameter, the set recoil amount caused by the change of the roll diameter does not correspond to the actual cloth fell movement amount. , resulting in the problem that the rung (stop section) cannot be effectively prevented from appearing as the loom stops during the entire weaving period
