ABSTRACT:
Independently actuable underwinding clearers are mounted adjacent to those lower portions of the machine's spindle assemblies upon which yarn underwindings are placed preparatory to the formation of yarn packages upon the upper portions of the spindle assemblies. Upon actuation thereof during each cycle of package building operation of the textile machine, the clearers separate the lengths of yarn interconnecting the underwindings with the yarn packages undergoing formation upon the spindle assemblies. The clearers preferably are actuated sequentially and pneumatically. A preferred mode of actuation of the clearers is by blasts of air emitted from a mobile servicing apparatus, such as a conventional pneumatic traveling cleaner, during movement of the apparatus along the length of the textile machine.
