ABSTRACT:
A method and apparatus for transporting a wound hollow yarn package having a loose yarn end from a yarn processing machine and, preferably, between yarn processing machines, while maintaining the loose yarn end in defined and fixed positions. The yarn package is gripped in the yarn processing machine by inserting a hollow gripper device into one end of the hollow yarn package and the loose yarn end is pneumatically positioned in the hollow gripper device. The yarn package is removed from the yarn processing machine and placed on a hollow pin of a transporting mechanism by the gripper device and the loose yarn end is pneumatically removed from the gripper device and positioned in the hollow pin of the transporting mechanism. The gripper device is then removed and the yarn package is transported, preferably to a second yarn processing machine. At the second yarn processing machine, the yarn package is gripped by a further gripper device and the loose yarn end is pneumatically removed from the hollow pin of the transporting mechanism and inserted into the gripper device. The yarn package is then moved from the transporting mechanism and placed in desired position in a second yarn processing machine by the gripper device. The loose yarn end is then pneumatically moved from the gripper device and positioned in desired position in the second yarn processing machine and the gripper device is removed.
