Abstract
Apparatus is disclosed for adjustably supporting the friction rollers for an open-end friction spinning unit having two friction rollers that are arranged next to one another and form a wedge-shaped yarn forming gap. The rollers are mounted by means of bearings on non-rotating axles. In the area of the end faces of the friction rollers the non-rotating axles are held by means of holding devices, the spacing of which can be adjusted. Four holding devices arranged in pairs are provided for the axles, where at least between the holding devices of one pair, an adjusting screw is mounted extending transversely to the wedge-shaped gap, by means of which the spacing of said holding devices and thus the size of the wedge-shaped gap, can be adjusted.
Claims14
Friction roller support apparatus for open end friction spinning machines of the type having two friction rollers arranged next to one another forming a wedge shaped yarn forming gap therebetween, said support apparatus comprising:
- a pair of non-rotating axle means and bearing means rotatably supporting the respective friction rollers on the axle means,
- four holding means arranged in pairs and at opposite ends of the friction rollers including receptacle means for receiving the axle means,
- and adjusting screw means disposed between one pair of holding means, said adjusting screw means extending transverse to the longitudinal extension of the wedge shaped gap and being operable to adjust the spacing of the holding means with respect to one another to thereby adjust the size of the wedge shaped gap.
