Description

Technical Field

[0001] The utility model relates to the technical field of textiles, in particular to an electronic multi-arm air-jet loom. Background Art

[0002] The electronic dobby air-jet loom is a machine type that organically combines the electronic dobby technology with the high-speed air-jet loom. The electronic dobby is used to promote the air-jet loom to weave cloth, thereby improving the uniformity and fineness of the cloth. The principle of the air-jet loom is to use a jet airflow to pull the weft yarn through the shuttle mouth of the shuttleless loom. Air is used as the weft insertion medium, and the compressed air flow ejected generates friction traction to pull the weft yarn, bringing the weft yarn through the shuttle mouth, and the purpose of weft insertion is achieved through the jet generated by the air jet. This weft insertion method can enable the loom to achieve high speed and high yield.

[0003] As disclosed in the authorization announcement number CN212445089U, an electronic multi-arm air jet loom is disclosed, which belongs to the field of textile machinery technology.
