Abstract
An arrangement for open-end friction spinning having rollers that are rotatably arranged next to one another in fixed relation is provided wherein the fiber feeding duct assigned to the wedge-shaped gap is also mounted stationarily. As a result, inaccuracies are avoided in adjustment of the mouth of the fiber feeding duct with respect to the wedge-shaped gap. For cleaning of the fiber feeding duct and the wedge-shaped gap, it is provided that the fiber feeding duct is connected to a compressed-air supplying pipe so that a jet of compressed air is blown through the fiber feeding duct into the wedge-shaped gap.
Claims25
An apparatus for open-end friction spinning including a pair of adjacently arranged friction rollers, both said rollers being rotatably disposed in a single common structural unit means, and fiber feeding duct means having a mouth portion, said rollers defining a yarn forming wedge-shaped gap therebetween and said mouth portion extending along said wedge-shaped gap, comprising:
- rigid connecting means for fixedly connecting said mouth portion of said fiber feeding duct means to said single common structural unit means rotatably supporting said pair of rollers, thereby causing said mouth portion to be positively located relative to said wedge shaped gap.
An apparatus for open-end friction spinning including a pair of adjacently arranged friction rollers rotatably disposed in structural unit means and fiber feeding duct means having a mouth portion, said rollers defining a yarn forming wedge-shaped gap therebetween and said mouth portion being disposed opposite said wedge-shaped gap, comprising:
- rigid connecting means for fixedly connecting said mouth portion of said fiber feeding duct means to said structural unit means rotatably supporting said pair of rollers,
- said fiber feeding duct means including a first part containing said mouth portion and a second part, said first part being fixedly connected to said structural unit means, said second part being displaceably supported relative to said first part.
An apparatus for open-end friction spinning including a pair of adjacently arranged friction rollers rotatably disposed in structural unit means and fiber feeding duct means having a mouth portion, said rollers defining a yarn forming wedge-shaped gap therebetween and said mouth portion being disposed opposite said wedge-shaped gap, comprising:
- rigid connecting means for fixedly connecting said mouth portion of said fiber feeding duct means to said structural unit means rotatably supporting said pair of rollers,
- said fiber feeding duct means including compressed air source connecting means for cleaning said fiber feeding duct means and said wedge-shaped gap,
- said apparatus including movable servicing means, said movable servicing means including compressed-air source means for supplying compressed air to said fiber feeding duct means and said wedge-shaped gap.
