Narrow fabrics or tubular fabrics are made of various yarns as raw materials. There are many varieties of belt fabrics, which are widely used in various industrial sectors such as clothing, shoe materials, luggage, industry, agriculture, military supplies, and transportation. In the 1930s, webbing was produced by hand workshops, and the raw materials were cotton thread and hemp thread. After the founding of the People's Republic of China, the raw materials for webbing have gradually developed to nylon, vinylon, polyester, polypropylene, spandex, viscose, etc., forming three major technologies of weaving, knitting, and knitting. The fabric structure includes plain weave, twill, satin, jacquard, Bilayer, multilayer, tubular and joint tissue.

Webbing is widely used, and the processing equipment of webbing also requires a high degree of automation and exquisite effect. The traditional cutting of webbing is based on the principle of cold shearing and hot shearing. The shearing effect has burrs, loose edges, uneven cuts or appearance Yellowing and scorching. In order to improve this situation, using the ultrasonic principle to cut the webbing, it can realize automatic cutting, ultrasonic sealing, no yellowing and coke, and achieve the ideal effect. The main equipment for webbing shearing are: automatic webbing shearing machine, automatic webbing punching shearing machine, and semi-automatic webbing shearing machine, all of which use the principle of ultrasonic to complete the shearing of webbing.
