Problems solved by technology

[0006] However, in a loom provided with more than two rung preventing devices, whenever the degree of rung occurrence changes, each rung preventing device is set by trial and error until it is set to the optimum level. Appropriate setting value, there is such a problem that the rung cannot be eliminated
In addition, each rung prevention device must be set one by one. In the process of setting one by one, there is a problem that the input of the set value is missed, and the setting operation is time-consuming as the number of input data increases.

Embodiment Construction

[0023] FIG. 1 shows the main parts of the loom 1 . In Fig. 1, the warp yarn 2 is sent out in sheet form from the warp let-off beam 3, passes through a plurality of heald frames 5 and reeds 6 through the back roller 4, forms an opening 7, and reaches the weaving fell 9 of the fabric 8. On the other hand, after the weft yarn 10 is introduced into the opening 7 formed by the upper and lower warp yarns 2 by a weft insertion device not shown in the figure, it is beaten to the fell 9 of the fabric 8 by the reed 6 to form the fabric 8 . The fabric 8 is taken up on the cloth roll through the guide roll 11, the press roll 12, the cover roll 14, and the press roll 13.

[0024] Let-off beam 3 and covering roller 14 are driven by let-off motor 16 and take-up motor 17 respectively. And the main shaft 22 is driven by the main shaft motor 23, and the rotation of the main shaft 22 is transmitted to the reed 6 through the motion conversion mechanism 18 of rotation→oscillating motion, as a bea...

Abstract

A loom with a filling bar preventing function comprises two or more filling bar preventing devices (21) , and a filling bar prevention data setting unit (20) that gives set values of filling bar preventing parameters to the two or more filling bar preventing devices (21). Set values for degrees of filling bars to be given to the filling bar preventing devices (21) are stored beforehand in the filling bar prevention data setting unit (20). Filling bar information about an expected degree of filling bars is given to the filling bar prevention data setting unit (20). The filling bar prevention data setting unit (20) selects the set values corresponding to the filling bar information given thereto, and gives the selected set values respectively to the filling bar preventing devices (21). The loom operates according to the expected degree of filling bars to prevent the formation of filling bars effectively.

Description

technical field [0001] The present invention relates to a loom with a crosspiece prevention device which properly sets the state of two or more crosspiece prevention devices corresponding to the degree of the crosspiece (strip-like fabric defects generated on the fabric due to the thickness of the weft beating). Functional loom. Background technique [0002] Since rungs (knitting segments) are produced for various reasons, various proposals have been made in the rung prevention technology according to the reasons. Representative techniques are described below. [0003] JP-A No. 54-106661 and the like describe a cloth fall control device. When the loom is stopped, the warp beam is rotated forward by a predetermined amount to move the cloth fall, thereby relaxing the warp tension and suppressing the weaving during the stop. Crosspieces caused by warp elongation. JP-A-59-43145 and the like describe a leveling device for the warp shedding device, which drives the heald frame ...
