  • Winding machines are generally designed so that the thread is passed to a driven spool through a thread guide which moves back and forth by means of a reverse thread roller.
  • the thread is fed at constant speed and the spool upon which the thread package is formed is driven by a friction roller. Consequently. the thread is wound up on the spool at a uniform speed independcntly of the increasing diameter of the roll being wound.
  • the end structural configuration of thread packages formed on such a winding machine is straight. Such thread rolls or packages are used in particular for the process of dyeing the thread.
  • thread package When the thread packages are intended for subsequent use on a processing machine. it is desired to form a conically shaped end structural configuration. It is known to swing the thread guide in the vicinity of the turning region so that conically shaped end configurations are formed on the thread package. That is. thread package is said to have a biconical structure.
  • a guide rail is used in conjunction with the moving thread guide so that the thread guide will swing in varying amounts as the diameter of the thread package increases.

  • Means is provided to cause the rod means to move in a continuous back and forth move ment.
  • an edge displacement of the thread can be achieved by the interengagement of the oblique shaped projection with the annular recess.
  • the so-called edge displacement of the thread at the side or ends of the thread package has the purpose of distributing the turning point of the thread on the spool sides over a certain inward area. That is.
  • the threads are brought to the extreme outside edges of the thread package and then the extreme turning point for the thread guide is changed to lay thread at a point displaced inwardly from the outermost edge of the thread package.
