ABSTRACT:
A loop-forming instrument relates to knitting machines wherein cam assemblies are used for displacing the loop-forming instruments, and includes a stem having a working end, portions of variable cross-section, a butt, a tail and a portion widening towards the working end. Disposed in the stem, intermediate of the butt and the widening portion, is a portion of constant cross-section abruptly changing to a narrowed part of the widening portion, the width thereof being considerably less than the width of the portion of constant cross-section. This makes it possible to strengthen the butt, to minimize concentration of stress in the working end set up in the moving loop-forming instrument and, thereby, to prolong the useful life thereof.
