Evacuation device of warp loosening roller in loom

Abstract

The invention provides a retracting device for an easing roller in a loom. The loom includes: an easing roller, which is swingably supported on a loom frame and is hung by warp yarns sent out from a warp shaft. The position is set so that at least a part thereof is positioned below the upper end of the warp beam in the up-down direction; the easing mechanism is connected to the easing roller and swings the easing roller so as to absorb The tension of the warp yarn produced by the loom changes in one cycle. The easing mechanism is configured such that the easing roller can be oscillated and displaced to a retracted position beyond the swing range of the easing roller during weaving, that is, the lower end of the easing roller is located further than the upper end of the warp shaft. Retreat position above. This device does not complicate the structure of the loom, and can easily move (elevate) the easing roller to a retracted position where the warp beam is not interfered with when loading and unloading the warp beam.

Description

technical field [0001] The invention relates to a device for retreating a warp roll in a loom, in particular to a device for retreating a warp roll in a loom comprising a warp roll and a warp-releasing mechanism, wherein the loom comprises: a warp roll, which While being swingably supported on the loom, it is wound by the warp yarn sent from the warp shaft, and the position during weaving is set so that at least a part of it is located at the upper end of the warp shaft in the vertical direction (more specifically, the warp shaft is referred to as the warp shaft). The upper end of the flange part) is located further below; the loosening mechanism is connected to the loosening roller and causes the loosening roller to oscillate, thereby absorbing the warp tension of the loom in one cycle accompanying weaving change. Background technique [0002] As a loom having the above-mentioned loosening mechanism, there is a loom disclosed in Patent Document 1, for example. In the loom...

Problems solved by technology

But in this case, the mechanism near the feeding device in the loom will become more complicated, and it will also lead to an increase in the overall cost of the loom.
