Problems solved by technology

[0014] However, with this prior art, it is necessary to provide the above-mentioned nozzle and a mechanism for supplying air (fluid supply pipe, electromagnetic on-off valve, etc.), and a device for controlling the injection is also required, so , the structure of the device used to form the weaving edge becomes complicated, and the cost of the device becomes high
Moreover, because the displacement of the ends of the weft yarns caused by the outermost warp yarns still occurs, it is not possible to stably form the desired weaving edge shape

Embodiment Construction

[0094] refer to Figure 1 to Figure 6 One embodiment of the weaving edge forming device of the present invention will be described. Figure 1 to Figure 6 The example shown is an example in which the present invention is applied to a shuttleless loom for weaving one of the rubber-reinforcing fabrics 1, that is, a tire cord fabric.

[0095] The so-called tire cord fabric refers to the rubber reinforcing fabric used to manufacture the carcass layer as the skeleton of the rubber tire, such as figure 1 As shown, it includes a cord weave portion 1a having a very coarse weft density and a plain weave portion 1b having a weft density denser than the cord weave portion, two weft portions having greatly different weft densities from each other. A rubber material is applied to the carcass portion 1a of the tire carcass 1, thereby manufacturing a carcass ply.

[0096] Figure 1 to Figure 6 The shown weaving edge forming device 30 is an air-jet type weaving edge forming device, which is...

Abstract

The invention provides a simple and cheap weaving edge forming device. In terms of the weaving part with carded weft density, the weaving edge forming device can stably form an arc weaving edge through the end of the weft cooperating with the density of the weft, and a rubber strengthening textile weaving loom of a rubber strengthening textile (1) having the weaving part with carded weft density (1a) is generated. The air spray type weaving edge forming device comprises over one weaving nozzles (32) which are disposed at the side of warp for weaving the end part (2a) of the lead-in weft. In the rubber strengthening textile weaving loom, the weaving edge forming device comprises a limiting device (20) which is disposed near the most front position (5) of a reed along the warp direction, and limits the opening of the warp (3) in a part of the warp array having warps at the most external side in the direction of weaving width.

Description

technical field [0001] The present invention relates to a weaving edge forming device used in a loom for weaving rubber-reinforced fabrics. Background technique [0002] As one of the selvedge structures of fabrics woven by a shuttleless loom, there is a weaving edge in which the ends of the drawn weft yarns are folded back into the warp openings into which the subsequent weft yarns are drawn, so that the weft yarns are drawn in. The ends are tucked into the fabric with the subsequent weft threads. As an apparatus for forming this weaving edge, an air-jet type weaving edge forming apparatus disclosed in Patent Document 1 is known. In addition, the operation of turning back the end of the drawn weft into the warp opening into which the subsequent weft is drawn is called weaving. In addition, the air-jet type weaving edge forming device is also called an air tucker (air tucker). [0003] The air jet type weaving edge forming device mainly has weaving heads arranged on both ...
