Abstract
The device for separating individual fibers of a fiber sliver comprises sliver feed rollers, sliver opening means comprising a press roller and a separating roller adapted to carry a stack of thin disks provided with combing elements which consist of teeth or wire points for separating the fibers and with drafting elements for parallelizing the fibers, and a duct for the delivery of freed fibers. The separator can be employed for spinning slivers containing either long or short fibers or a mixture of both.
Claims11
A device for separating individual fibers of a sliver, comprising:
- means for feeding the sliver;
- means adjacent said feeding means for opening the sliver, comprising a combing and drafting cylinder, said combing and drafting cylinder being constituted by a shaft having a stack of disks mounted thereon, the edges of said disks having teeth or needles for combing the sliver and smooth portions on the periphery thereof for drafting the sliver, said disks being relatively angularly offset from one another, a pressure roller in close proximity to said combing and drafting cylinder;
- a guiding means mounted between said feeding means and said combing and drafting cylinder;
- and
- fiber discharging duct means positioned downstream of said opening means.
