Abstract
An arrangement is disclosed for spinning staple fibers to a yarn which has a feeding and opening device which opens up fiber material supplied in the form of slivers into a individual fibers, and a disk-type collecting element which takes over the separated fibers. It is provided that the collecting element has a conical fiber collecting surface which ascends toward the outside with centrifugal forces assisting in compacting the separated fibers to a composite.
Claims22
An arrangement for spinning staple fibers into a yarn, comprising:
- a feeding and opening device which opens up fiber material supplied in the form of a silver into individual fibers,
- a bowl-shaped collecting element which receives the separated yarns and has a rotatable air permeable collecting surface which is aligned approximately tangentially with respect to an opening roller of the feeding and opening device,
- apparatus for rotating the collecting surface,
- and a suction device assigned to the collecting surface on a side facing away from the opening roller and facing the collecting surface by means of a suction slot which tapers in the circumferential direction to a withdrawal point which is followed by a twisting element and a withdrawal device,
- wherein the bowl-shaped collecting element is provided with a truncated-cone-shaped edge area which ascends toward the outside and which si constructed as an annularly extending bowl shaped fiber collecting surface on the radial inside of said edge area,
- wherein the suction device is disposed at the opposite side of said edge area and wherein said yarn is withdrawn from the collecting surface in a direction substantially parallel tot he travel direction of the collecting surface at the withdrawal point.
