ABSTRACT:
A yarn end loosening apparatus for a textile machine includes first and second chamber portions which are positionable to form a gas guide chamber for directing jet streams of gas against the yarn package therein to effect loosening of a yarn end. A movement device selectively moves the first chamber portion between the chamber 4 main position in which it forms a gas guide chamber with the second chamber portion, a clearance position in which it permits a tube support member which supports a yarn package to travel away from the winding station of the textile machine and a travel blocking position in which a following tube support member which supports a fresh yarn package is prevented from traveling beyond the unwinding location at which the yarn package is unwound. Another movement device is also provided for moving the second chamber portion to separate each tube support member from a subsequently following tube support member. The chamber movement devices include vertical shafts on which the chamber portions are mounted for pivoting of the chamber portions about vertical axes.
