A METHOD, AN APPARATUS, AND AN INTERLACER DEVICE FOR THE AUTOMATIC FINISHING OF A COP OF WOUND YARN HAVING A TAIL

摘要

An apparatus (10) for the automatic finishing of a cop (12) of wound yarn having a tail comprises means for supporting at least one cop (12) and means for winding the tail of the cop (12) onto an outer surface (16) of the cop, forming at least one loop (30) of turns in the region of at least one predetermined position along a longitudinal axis (X-X) of the cop (12). An interlacer device (32) is provided for creating at least one connection point in the loop (30) in order to secure the turns directly on the cop (12). The interlacer device (32) is mounted on a rod (34) of a pneumatic cylinder (36) which is movable between a retracted position relative to the cop (12) and a working position in which it is close to the loop (30) in order to create the connection point.
