Description
Technical Field
[0001] The utility model relates to the technical field of textile equipment, in particular to an adjustable fabric dividing device for a jet loom. Background Technique
[0002] A jet loom is a shuttleless loom that uses a jet of air to draw the weft yarn through the shed. Its working principle is to use air as the weft insertion medium, and the compressed air jet ejected generates frictional traction on the weft yarn to draw the weft yarn through the shed, and the jet generated by the jet is used to achieve the purpose of weft insertion. Due to its wide fabric adaptability, the jet loom has become the preferred model in the current weaving industry. Generally, a scissor device for dividing the fabric is provided on the frame of the jet loom.
