Description

Technical Field

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

[0002] Loom, also known as spinning machine, weaving machine, cotton spinning machine, etc., early looms were all human-driven looms. Shuttleless loom technology has been studied since the 19th century and has been gradually introduced to the international market since the 1950s. Since the 1970s, many new shuttleless looms have been put on the market. Shuttleless looms have achieved remarkable results in improving fabrics and improving the efficiency of looms. They have been widely used in countries around the world and have accelerated the process of weaving equipment transformation. The share of shuttleless looms in many developed countries has reached about 80%, and there has been a large-scale replacement of shuttle looms with shuttleless looms; at this stage, when trimming the fabric produced by the loom, the fabric is basically fixed manually and then cut with a cutter. This manual fixation method is not safe enough and requires a lot of labor. Utility Model Content
