Problems solved by technology

[0004] The above technique controls the warp let-off beam based on the tension detected from one warp piece, but the tension of the warp piece with the lower warp consumption rate must also be controlled to At the same level of tension, a complex structure such as a relaxation device becomes necessary
In addition, the warp yarn tension of the warp yarn sheet with a low warp yarn consumption rate fluctuates greatly every time we weave one cycle with the relaxation device, so the quality of the fabric will deteriorate.
On the other hand, when the number of warp yarns in the warp yarn piece with high warp yarn consumption rate is less than that of the warp yarn consumption rate low warp yarn piece, the warp let-off axis is controlled according to the tension of the warp yarn piece with a small number of warp yarns, so there is a danger of increasing the setting error.

Embodiment Construction

[0032] figure 1 and figure 2 Shown is the loom let-off device 1 of the present invention. also, figure 2 Only one side of the pair of left and right racks 8 is shown, and the other side is omitted.

[0033] exist figure 1 and figure 2 Above, the warp let-off device 1 of the loom has a plurality of, for example, two first relaxation cylinders 2 and second relaxation cylinders 3 , and also has a let-off beam 4 and a guide roller 6 . The left and right ends of the shafts of the first buffer drum 2 and the second buffer drum 3 are rotatably supported by bearings 18 and 19, respectively, at the front ends of a pair of left and right first buffer levers 11a and second buffer levers 12 .

[0034] The base end portion of the first relaxation lever 11a is fixed to the shaft 10 of the guide roller 6 in a locked state, and the base end portion of the second relaxation lever 12 is rotatably supported relative to the shaft 10 of the guide roller 6. 20 supported. On the shaft 10...

Abstract

In a let-off device (1) for a loom with which warp sheets (5) from one delivery beam (4) are divided into a plurality of parts, independently guided to each of the easing rolls (2) and (3) and a warp opening (9) is formed for each of the warp sheets (5a and 5b), the delivery beam is driven on the basis of tension of only the one warp sheet (5a) so that warp tension has set tension for one warp sheet (5a) and the easing roll (3) corresponding to the other warp sheet (5b) makes only an easing movement by an easing apparatus (14) for other warp sheet (5b). The easing apparatus (14) has corresponding easing rolls and the easing spring (16) exerting applied force to the other warp sheet (5b) by the easing rolls, the easing spring is set at constant tension force of the other warp sheet generated according to one warp sheet and abb interleaving number is different to the other warp sheet and abb interleaving number, which is different to the setting tension force, leading the easing rolls to process easing movement normally.

Description

technical field [0001] The present invention relates to a warp let-off device of a loom, and more particularly to a mechanism for setting warp yarn tension during the process of guiding a warp yarn sheet with a relaxation cylinder. Background technique [0002] Patent Document 1 discloses a warp tension control technique related to a let-off device of a loom. In this technology, the warp yarn sheet from the warp let-off beam is divided into two pieces, and the warp yarn opening is formed on each warp yarn sheet during the process of independently guiding each warp yarn piece to the corresponding relaxation cylinder, and springs are respectively applied to each relaxation cylinder. elastic so that proper tension is applied to the corresponding warp pieces. If this tension control is used, the warp yarn tension of the warp yarn that has more interlacing with the weft yarn and the warp yarn consumption rate among the divided warp yarn pieces can be detected, and the warp let-...
