Abstract

A machine for producing yarn loops comprises a rotary winding flyer or member having a discharge end through which the yarn emerges. A winding means for collecting the yarn loops is provided and transfers the loops to a conveyor. In order to secure the end of the yarn as it emerges from the discharge end upon start up of the machine a pair of rings are provided which can be moved relative to each other by a powered device. The rings define complementary surfaces between which the end of the yarn is passed prior to the rings being moved into engagement with each other to secure the end of the yarn. The rings are moved apart after at least one yarn loop has been produced.
