Abstract: A machine for stretch-break converting man-made fibers or fiber slivers, h the machine having one or more distortion zones, one of which can be embodied as a heating zone, and one or more breaking zones, whereby the distortion and breaking zones can be disposed in several superimposed levels. The machine also has a tow-drafting mechanism, as well as a delivery mechanism for stretch-break converted fiber slivers. So that tows having a greater overall weight can be processed, the drafting mechanism is spread out such that a plurality of separate tows can be individually guided parallel to and independently of one another next to and/or above one another. The width of the components of the distortion and breaking zones is greater than 270 mm.

Abstract: An apparatus for continuously steaming filament tows or fiber slivers following a stretch-break converting machine. A steam channel receives saturated steam for releasing and eliminating shrinkage from filament tows or fiber slivers in the channel. To improve the elimination of shrinkage, the counterpressure against the filament tows or fiber slivers in the steam channel is adjustable. To effect this adjustment, a pivotable flap can be disposed at the outflow end of the steam channel to vary the cross-sectional area of the latter.

Abstract: A mechanism for eliminating impurities from fibrous material, in particular cotton, having at least two card-clothed rolls (22, 23) arranged after a feed mechanism and a screening drum (3) to which said fibrous material is fed by means of an airstream. A housing closely encloses the two card-clothed rolls. Interposed in the housing are separating openings including separating edges. One of said two card-clothing rolls (23) cooperating with the other of the two card-clothed rolls has a take-off and loosener roll for the fibrous material and the centrifugal forces at the circumference of the second card-clothed roll (23) being greater than at the first card-clothed roll (22). A third card-clothed roll is positioned in carding relation with the first card-clothed roll. Another take-off and loosener roll (52) is positioned for removing fibers from the third card-clothed roll (5).
