Abstract
This application relates to an apparatus for winding strandular material known in the textile industry as a takeup device. The overall arrangement of the device incorporates a stationary supporting spindle onto which a rotatable package support is mounted for receipt of strandular material wound thereon. The support and the strandular material wound thereon as the package is progressively built, is adapted for contact with a rotatable drive drum. A traverse device to guide the strandular material to the rotatable package and control the manner in which the strandular material is wound thereon is also included. Both the drive means and the traverse means including the motors therefor are mounted on a freely vertical movable carriage supported within a frame member and uniquely counterbalanced by a pulley suspended counterweight system. The spindle and the package support are mounted on said frame independent of such carriage. The drive and traverse means are thus free to move upwardly while the package progressively builds on the stationary spindle. Initial pressure means are further included to apply an initially higher pressure between the drive means and the package support to prevent skidding during the required acceleration of the support to its operational winding speed. Additionally, differential pressure means are included to progressively decrease the amount of drive pressure between the drive drum and the package as the package builds.
