Description

Technical Field

[0001] The utility model relates to the technical field of looms, in particular to an edge trimming mechanism of a loom. Background Art

[0002] Loom, also known as spinning machine, weaving machine, cotton spinning machine, etc., early looms were all driven by manpower. Traditionally, looms that use yarn for weaving can be divided into two major categories: weaving and knitting. Looms include primitive shuttle looms and new shuttleless looms. Shuttleless looms mainly include rapier looms, air-jet looms, water-jet looms and projectile shuttle looms. The shearing mechanism is installed on the loom to cut the cloth.

[0003] At present, after the loom processes the fabric, there will be a large number of thread ends on the sides of the woven fabric. It is necessary to use a trimming device to trim the sides of the fabric to facilitate the subsequent processing of the fabric. During the trimming process of the fabric, the surface of the fabric needs to be kept flat. If wrinkles appear on the surface of the fabric, the trimming device will damage the side of the fabric, affecting the subsequent fabric processing. Therefore, we propose a trimming mechanism for a loom to solve the above problems. Utility Model Content
