Abstract
The present invention concerns an apparatus for winding threads or yarns and similar strands, in which a friction drive roll and a bobbin support roll are provided. The latter is supported only at one end, and the other end is free, in such manner that easy operation is possible. In arrangements of such type any deviation, however small, of the two rolls from their correct, parallel position, is to be avoided if correctly built bobbin packages are to be produced in the winding process. This is achieved according to the invention in that a coupling means, coupled or connected with the bobbin support roll, which moves during the winding process, brings about a forcible parallel alignment of the two rolls.
