ABSTRACT:
For a separating roll, which finds application on an open end spinning machine, the proposal is made that a spiral trim wire be preformed and precoated before the trim wire is installed upon the circumference of the roll. In this way, separating rolls of the most varying materials may be employed since the rolls themselves need not undergo the coating process. Further, the trim wire may be preformed into a spiral before fitting on the separating roll. Moreover, a process for the production of the trim wire is presented. During the process of coating, the preformed spiral windings are held at an axial distance from one another.
