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.

Claims25

Dependent claims

A textile yarn winding machine having a plurality of yarn winding positions aligned along at least one side thereof, and with each winding position comprising

at least one winding spindle adapted for coaxially receiving two or more bobbin tubes,
yarn traversing means for traversing each of a plurality of running yarns along a predetermined yarn traverse stroke to form a cross wound yarn package upon each associated bobbin tube, and
a plurality of yarn handling assemblies operatively associated with each winding position, with each of said yarn handling assemblies being associated with a respective one of said yarns being wound at said position and comprising
(a) yarn catching means,
(b) yarn severing means for severing the running yarn while the yarn is disposed in said yarn catching means, and
(c) yarn suction means for withdrawing the severed yarn end from said yarn catching means, and
means mounting each assembly for movement along a predetermined path of travel between a first end position located on the upstream side of said winding spindle and wherein said yarn catching means is disposed in said predetermined yarn traverse stroke so that the running yarn moves into said yarn catching means where it is adapted to be severed and withdrawn by said severing means and said suction means, and a second end position located on the opposite side of said winding spindle and where the running yarn is adapted to be engaged by a yarn catching and severing notch or the like on the asociated empty bobbin tube mounted on said winding spindle and then again engaged by said yarn traversing means to commence winding of the running yarn upon the empty bobbin tube.
