Abstract

The apparatus is particularly adapted for the formation of quite large and heavy strand packages. Its spindle assembly is so constructed as to permit rapid but exceedingly secure mounting thereon of the bobbins upon which such packages are wound, and as to satisfactorily withstand the severe stresses imposed upon its components by the weight of such packages. In a preferred embodiment of the apparatus, wherein the spindle assembly is mounted for pivotal translatory movement toward and away from a pressure roll engageable with the periphery of a strand package upon the spindle assembly, improved fluid-pressure means controls and at desired times produces the movement of the spindle assembly relative to the pressure roll. Such fluid-pressure means utilizes advantageous aspects of both hydraulic and pneumatic systems and, among other benefits, cushions return movement of the spindle assembly back toward the pressure roll following such temporary displacement therefrom as might be occasioned by a bulge or protuberance upon the periphery of the strand package.
