Reciprocating yarn guide arm has structured mounting and end yarn guide sections, with an intermediate carrier section, of a material which withstands the yarn draw forces and alternating speed changes

摘要

The arm for a reciprocating yarn guide has a mounting section (216), a yarn guide section (217) with a yarn guide slit (224), and a connecting carrier section (218). A drilling (223) at the mounting section takes the motor axis, for the yarn guide movements. The arm material is at least partially of fibers of carbon, boron, or a hybrid compound fiber material. The mounting section is wider than the yarn guide section, and the tapering of the carrier section is in the shape of a polynome at least of the first degree.
