A web of fibers delivered from a drawing machine is assembled into a sliver which passes into a guide duct, then passes between takeup rollers into a can coiler. Downwardly inclined air-escape holes are pierced in the wall of the guide duct in order to discharge the air entrained by the sliver. There is consequently no swelling of the sliver on the delivery side of the takeup rollers and no pressure rise towards the guide duct inlet, thereby facilitating the introduction of the web into the duct.

Device for guiding a sliver into a can coiler

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.

Fiber separator for feeding a freed-fiber spinning unit

Apparatus for the automatic infeed of a fibre sheet into a coiler comprises a smooth-surfaced transverse guide 6 to be placed at the delivery side of a pair of drawing rollers 1, 2. The guide 6 has an orifice 7 for gathering into a tuft the fibre sheet 3 coming from said pair of drawing rollers, a cylindrical outlet tube 8 extending said orifice 7, pneumatic means 18 for drawing the tuft into the outlet tube 8, and a pair of draw rolls 9 set at the downstream end of the outlet tube. The invention may be applied to the introduction of a fibre sheet into a coiler, the fibre sheet leaving the last pair of rollers of the drafting train of a machine.
