Abstract

A yarn winding machine having a suction apparatus for withdrawing the severed advancing yarns during the bobbin changing operation. The suction apparatus comprises a tubular duct which extends the length of the winding machine, and the duct mounts a yarn intake tube of relatively small diameter in front of each of the side by side winding stations of the machine. A yarn is adapted to be sucked into and through each of the yarn intake tubes by the relatively high speed air current flowing therethrough, and the yarn then advances into the tubular duct and to a waste container.
