Abstract
An open end spinning unit is disclosed which includes a feeding device forming a fiber beard nipping line for a fiber beard extending downstream thereof. An opening device acts on a downstream end area of the fiber beard to open the fiber beard into separate fibers. A movable fiber take-up surface is provided separate from and downstream of the opening device for transporting the fibers to a yarn formation line. A fiber beard support guide guides the downstream end area of the fiber beard and the separated fibers so that the fibers continuously extend in a substantially stable direction without deflection as they travel between the nipping line and the take-up surface.
Claims31
An open-end spinning unit, comprising:
- a feeding device forming a fiber beard nipping line for a fiber beard extending downstream of the nipping line,
- an opening device acting on a downstream area of the fiber beard to open the fiber beard into separate fibers,
- and a movable fiber take-up surface downstream of the opening device and directly downstream of the end area of the fiber beard which transports the fibers to a yarn formation line,
- wherein said opening device includes a fiber beard support guiding the downstream end area of the fiber beard and the separated fibers so that the fibers continuously extend in a substantially stable direction without substantial deflection as they travel between the nipping line and the take-up surface.
An open-end spinning unit, comprising:
- a feeding device forming a fiber beard nipping line for a fiber beard extending downstream of the nipping line,
- an opening device acting on a downstream end area of the fiber beard to open the fiber beard into separate fibers,
- and a fiber transport take up surface separate from the opening device and downstream of the end area of the fiber beard, which fiber transport take-up transports the fibers to a yarn formation line,
- wherein said opening device includes fiber beard support means for guiding the downstream end area of the fiber beard so that the fibers continuously extend in a substantially stable direction without deflection as they travel between the nipping line and the take up surface.
A method of making yarn using an open spinning process comprising:
- feeding sliver in a feeding device forming a fiber beard nipping line for a fiber beard extending downstream of the nipping line,
- opening the fiber beard with an opening device acting on a downstream end area of the fiber beard to open the fiber beard into separate fibers,
- and taking up the fibers on a fiber transport take up surface downstream of the opening device and downstream of the end area of the fiber beard which transports the fibers to a yarn formation line,
- wherein said opening includes supporting the fiber beard at fiber beard support structure which holds the downstream end area of the fiber beard so that the fibers continuously extend in a substantially stable direction without deflection as they travel between the nipping line and the take up surface.
