Abstract
A textile yarn winding machine and method for winding yarn utilizing a rotatable package supporting spindle, two continuous belts movable oppositely along two respective traversal spans for traversingly moving yarn longitudinally along the package, and rotating yarn engaging fingers adjacent opposite ends of the package for positively transferring the yarn between the belts at the package ends. The belt traversal spans extend in crossing relationship from respectively opposite yarn engaging locations closely adjacent opposite ends of the package to respectively opposite disengaging locations spaced from the other package end to effect quick yarn reversals. The yarn engaging fingers move in circular reversal paths to positively engage the yarn at the disengaging locations of the spans, disengage it from the belt guiding it, and move it to the engaging location of the other belt. The rotational speed of the spindle is variable in relation to a selected yarn characteristic or feeding condition to control the package surface speed and thereby control the characteristic or condition. The longitudinal speed of movement of the belts is variable to maintain its ratio to the spindle rotational speed constant, and to periodically change such ratio to control the yarn winding angle.
