Problems solved by technology

However, at this time, when the cause of the initial stop includes warp breakage and other causes, if the warp breakage is ignored, the warp dropper device detects a real warp breakage and outputs a warp breakage detection signal, but the loom is restarted. , so there will be the following problems: the loom stops again immediately after restarting, and it is necessary to perform repair operations, etc., which is time-consuming and laborious

Abstract

A tire chord weaving apparatus (1) includes a warp tension adjusting device (3) and a loom (4). The warp tension adjusting device (3) includes a dancer roller (10a, 10b) for equalizing tensions of warp yarns drawn from the creel device (2) and a dropper device (8) disposed upstream of the dancer roller (10a, 10b). The loom (4) weaves a tire chord fabric from the warp yarns supplied via the warp tension adjusting device (3). In the tire chord weaving apparatus (1), by using an urging roller (10a) that moves up and down and that is disposed above the warp yarns so as to extend in a direction perpendicular to a direction in which the warp yarns are fed and an urging device (11) including a fluid-pressure cylinder (15) for applying an urging force (F) to the urging roller (10a) in such a direction that the urging roller (10a) is lowered, the urging force (F) is applied to the urging roller (10a) over a period from a first time after a time at which the loom (4) is stopped to a time at which the loom (4) is restarted.

Description

technical field [0001] The present invention relates to a warp yarn tension adjusting device for a cord weaving device that weaves a cord fabric including a cord weaving part and a flat plain part, wherein the cord weaving device includes a creel device for supplying warp yarns, A warp yarn tension adjusting device of a tension adjusting roller for uniform tension of a plurality of warp yarns drawn out from the creel device, and a loom for weaving a cord fabric with the warp yarn supplied through the warp yarn tension adjusting device. Background technique [0002] Cord fabric refers to a kind of woven fabric for rubber reinforcement used to manufacture the tire carcass layer and belt layer that become the rubber tire frame, including the cord weaving part with a weft density that is much sparser than ordinary fabrics and the weft density than the cord weave part. Dense tabby sections. [0003] Such as Figure 17 As shown, the main structure of the cord fabric weaving devic...
