Abstract
An arrangement for open-end friction spinning is disclosed having two adjacently arranged friction rollers driven in the same rotational direction forming a yarn forming wedge shaped gap or slot. A fiber opening device is provided for opening fibers to be spun and a fiber feed channel guides the fibers from the opening device to the yarn forming gap. A yarn withdrawal device is provided for drawing off the produced yarn in the direction of the longitudinal extension of the yarn forming gap. The opening device is configured to simultaneously treat a plurality of fiber bands and the fiber feed channel is divided into several sections in its cross section. The mouths of the feed channel sections are disposed to open to the yarn forming gap at least partially one behind the other along the longitudinal extension of the yarn forming gap.
Claims18
Apparatus for open end friction spinning comprising:
- a pair of friction rollers rotatably drivable in the same direction and arranged adjacent one another to form a yarn forming wedge shape gap therebetween,
- opening device means for opening fiber band means into individual fibers,
- fiber feed channel means leading from the opening device means to fiber feed channel mouth means opening toward the yarn forming gap,
- and yarn withdrawal means for withdrawing yarn in the longitudinal direction of the yarn forming gap,
- wherein, said opening device means includes opening roller means having at least one opening roller for simultaneously opening a plurality of separate fiber bands making up the fiber band means and wherein the fiber feed channel means is divided in cross-section into plurality of sections having respective channel mouth section means opening into respective different locations in the longitudinal direction of the yarn forming gap.
