PROCEDIMENTO PER RIPRENDERE LA FILATURA DI UN FILO.

摘要

A method of piecing yarn in the operation of an open end rotor spinning machine that includes applying the suction that picks up the yarn end from the bobbin package for an extended predetermined length of time longer than the optimal minimum length for a normal piecing operation, with the extended suction being of a time sufficient to remove an estimated extended length of defective yarn, either determined by sensing the absence of sliver or after two or three sequential unsuccessful piecing attempts.
