The temple thorn shaft is a necessary component of the loom required by the weaving process. It must be equipped on both shuttle looms and shuttleless looms. However, shuttleless looms are more demanding.
1. The function of the temple support device of the shuttleless loom
During the weaving process of the fabric, due to the tension of the warp and weft yarns, the fabric width shrinks, resulting in a difference between the fabric width and the reed width at the weaving fell. , cannot reach the predetermined width of the fabric, and cause the warp yarns to have a large inclination, increase the friction between the side warp yarns and the reed blades, increase the breakage of the side warp yarns, and deform and damage the side reed blades. The greater the tension of the fabric, the greater the impact on the reed, and the breakage rate of the corresponding warp yarns will also increase. Installing the temple device is mainly to control the shrinkage of the fabric at the cloth fell, to achieve the predetermined width of the fabric, and to reduce Broken ends of the edge warp yarns and deformation and damage of the edge reed blades.
2. Conditions that the shuttleless loom temple device should meet in the weaving process
The shuttleless loom temple device of various models should be matched with the corresponding temple box, and the temple box should make the fabric In contact with the circular surface of the temple device, the arc-covered surface formed by it should be able to control the fabric shrinkage. The copper thorn ring, rubber roller, steel licker-in and other requirements on the temple device (concentric copper thorn ring as shown in the figure) As shown in Figure 12-1, the rubber roller is shown in Figure 12-2, and the steel licker-in roller is shown in Figure 12-3), the operation is flexible, the thorn tips are sharp, and there are no hooks or broken ends. The exposed height should be reasonably matched according to the thickness of the fabric. , from low to high, can firmly hold the fabric during operation without damaging the surface of the fabric, and effectively hold the edge of the fabric to prevent it from shrinking. The threads and thorn tips on the rubber roller and steel licker-in should be spiral The thorn path on the copper thorn ring should be circular, which can achieve the predetermined lifting effect according to the angle change of the thorn ring seat.
