Abstract
A yarn handling apparatus is disclosed for a textile yarn winding machine of the type having a plurality of side by side winding positions extending along the length of the machine. A separate yarn handling apparatus is associated with each winding position, and each handling apparatus comprises an assembly which includes yarn catching means, yarn severing means, and yarn suction means for withdrawing the severed yarn end. The assembly is mounted for movement along a predetermined path of travel between a first end position located on the upstream side of the spindle and where the yarn catching means is adapted to engage the running yarn as it moves in its predetermined yarn traverse stroke, and a second end position located on the opposite side of the winding spindle and where the running yarn is adapted to be engaged by a yarn catching and severing notch on the associated empty bobbin tube. An embodiment is also disclosed wherein the winding machine includes a draw roll system, and there is further provided a movable yarn suction means for threading the advancing yarn about the draw roll system so that the yarn is helically disposed about groups of the draw rolls.
