1. Types and structures of shuttleless loom temple support devices
(1) Shuttleless loom temple support devices are mainly divided into four categories according to the type of loom; Projectile loom temple support devices , air-jet loom side support device, rapier loom side support device, water-jet loom side support device.
There are many types of loom models in each major category of temple support devices. Depending on the loom model, the temple support device specifications and installation size and shape are also different. Therefore, each major category of temple supports The device is also divided into many varieties.

(2) The structure of the temple support device of the shuttleless loom mainly includes the four modes of copper licker-in operation, polyurethane ring operation, rubber roller operation and steel licker-in operation, as shown in Figure 12-4~Figure 12 -7 shown. Thick fabrics, woolen fabrics, and medium-thick fabrics must be equipped with a temple device running a copper thorn ring, but the needle exposure height and needle arrangement need to change according to the thickness and warp and weft density of the fabric. Light fabrics, filament fabrics, Low extra high density fabrics need to be equipped with a silk temple device running with rubber rollers. Low extra high density fabrics with high tension and silk fabrics need to be equipped with steel temple devices running with steel licker-in rollers.
2. Technical requirements for shuttleless loom temple support device
