ABSTRACT:
A yarn winding machine is equipped to compensate the sag of the spool mandrel (5) with a speedometer roll (7) which is disposed so that it can press radially against the surface of the yarn packages being wound and which is mounted so as to damp vibrations. The mounting for the speedometer roll (7) includes a peg (17) fastened on a yoke (11) which supports the speedometer roll (7). The peg (17) extends into a hole (21) in a carrier (19) for the yoke 11 and is connected to the wall of the hole (21) through O-rings (23) on the surface of the peg (17) so that it is flexible with respect to rotation.
