ABSTRACT:
A winder for filamentary material includes a cutter/aspirator which severs a filament and sucks-in same under negative pressure. The filament travels through a stiff tube while the cutter/aspirator and tube are lowered toward a filament throw-on device as a filled package is being replaced. The stiff tube is connected to a saddle which is mounted on a driven endless belt. The belt travels across an open side of a vertical chamber. A waste duct communicates with the chamber to create a negative pressure therein which is communicated through the belt and to the tube. As the tube is lowered, it is maintained continuously in communication with said chamber to conduct the filament to waste.
