Description

Technical Field

[0001] The utility model relates to the technical field of water jet looms, in particular to a four-jet needle assembly device for water jet looms. Background Art

[0002] The water jet loom is a shuttleless loom that uses a jet of water to pull the weft yarn through the shed. Its working principle is to pull the weft yarn by jetting water, so that the frictional traction on the weft yarn is greater than that of air jet weft insertion, and the diffusion is small. It is particularly suitable for the weft insertion of filaments such as synthetic fibers and glass fibers with smooth surfaces. At the same time, the water jet loom can also increase the conductivity of synthetic fibers and effectively overcome static electricity in weaving. In addition, the jet weft consumes less energy and has the lowest noise.

[0003] The four-jet needle assembly for a water jet loom is a device for a water jet loom, comprising a bracket, a needle holder, a needle body and a needle. Specifically, the assembly has four needle holders, each of which is equipped with a needle body, and each of which is equipped with a needle.

[0004] This design has its own specific functional characteristics. Among them, the center of the minimum design permissible space of the first needle is located on the bisector of the minimum permissible warp opening in the weft flight stage of the water jet loom. Among the other three needles, at least the centers of the minimum design permissible spaces of the third and fourth needles far away from the cloth fell are deviated on both sides of the bisector. This design allows the water jet loom to weave more varied and complex chemical fiber fabrics.
