Reduce the beating area to solve the problem of wear of profiled reed

At present, air-jet looms have been widely used in our country, but the special-shaped reeds damaged by air-jet looms are more damaged. Due to the particularity of the special-shaped reeds, the maintenance is more difficult, and the corresponding maintenance costs are much higher than that of ordinary reeds . Shaped shaped reed shaped groove or weft flight channel, therefore, the shape of the reed also directly affects the quality of the product. Whether it is from reducing consumption, or from product quality considerations, it is necessary to conduct an in-depth discussion of this issue.
For a larger breed beat breed, you can reduce the beating area to reduce the deformation of reed wear. In the process of adjusting the machine, the opening time is beating the warp when the warp tension and fabric tension are corresponding increases, and beating the end of the shed anterior horn increases, the weft is not easy to reverse dial back, so beating area to reduce; The contrary increases.
Increase the machine tension can make the warp and fabric rigidity coefficient increases, beating the process of reducing the amount of movement of the cloth mouth, beating the corresponding reduction in area, on the contrary the beating area also increased. In actual production, we often use to adjust the tension on the machine to control the size of beating area. However, it should be noted that for the varieties with more serious warps on the edge, excessive tension on the machine will aggravate the wear of the edge warp on the side reed. In this case, the smaller on-board tension should be selected and must be combined according to specific varieties Beating area and the edge of the cloth to determine the reasonable tension on the machine. Behind the raised beam easily tighten the weft, the beating area of the fabric is reduced, but pay attention to the determination of the position of the back beam must consider the appearance requirements of the fabric.
