Description

Technical Field

[0001] The utility model belongs to the technical field related to edge trimming devices, and particularly relates to an edge trimming device for an air jet loom. Background Art

[0002] Air-jet looms use airflow to insert the weft yarn. Because the weft yarn is guided from one end of the loom to the other, burrs form at both ends. Once the fabric has left the weaving fell a certain distance, the remaining edges need to be trimmed to create a smooth edge. This requires a trimming device, a crucial auxiliary device for textile machinery. Its primary function is to trim the fabric edges during the weaving process, ensuring a smooth, even edge. Existing trimming devices fail to secure the fabric, hindering cutting quality. Utility Model Content
