ABSTRACT:
A mechanism for use in a textile machine for transporting along a predetermined desired path of travel an end of a continuous yarn or the like, as follows. An elongate tube extends along and conforms to the contour of the predetermined desired path of travel of the yarn end. A freely displaceable piston is positioned within the hollow interior of the tube for movement within the tube along the length thereof. Selectively operable pneumatic devices are connected with the hollow interior of the tube for selectively moving the piston from one end to the other end thereof. A freely slidable, ring-like member is positioned at least partially around the outside of the tube and is magnetically coupled with the piston through the tube for movement along the length of the tube. A gripper device is carried by the ring-like member for holding and carrying the yarn end during selective movement of the ring-like member along the tube for transporting the yarn end along the predetermined desired path of travel. The mechanism is particularly useful with a two-for-one twister textile yarn processing machine and may be mounted at each spindle assembly thereof or may be carried by a movable carriage which is selectively moved to a desired spindle assembly location.
