ABSTRACT:
A yarn end loosening apparatus is provided for performing yarn end loosening operations on yarn packages. The yarn end loosening apparatus includes a chamber for directing streams of air relative to a yarn package disposed within the chamber to effect loosening of a yarn end from the yarn package. Additionally, the yarn end loosening apparatus includes an assembly for introducing air streams from, respectively, a taller package jet nozzle and a shorter package jet nozzle, the jet nozzles being spaced from one another to each direct a stream of air at the axial location of a type of yarn package having a predetermined axial length. Additionally, the yarn end loosening apparatus includes a device for selectively controlling the supply of air through the taller and shorter package jet nozzles such that only a selected one of the jet nozzles directs air into the chamber during a yarn end loosening operation.
