Embodiment Construction

[0039] figure 1 An embodiment of the prior art is shown. In this case, a lap sheet 2 conveyed by a gripper assembly 1 (referred to simply as a gripper) is fed by a supply roller 3 to a pair of detaching rollers 5 . The pair of detaching rollers 5 in this case comprises a detaching roller 5a and a pressure roller 5d. The fiber ear 7 (the end of the lap sheet) protruding from this open holder 1 in the front position is placed on the fiber sliver 10 or the rear end 8 of the carded sliver and is transported together with it into the jaws of the detaching roller pair 5, which is caused by the forward movement of the detaching roller pair 5. Fibers not held by the holding force of the lap sheet 2 or by the clamp (nipping point of the feed roller) are unraveled from the composite structure of the lap sheet by the clamping action at the nip. During the separating operation, the fiber ear 7 is additionally drawn by the upper comb 9 . The upper comb in this case causes the rear end ...

Abstract

The present invention provides detaching rollers (5a, 6a) of a carding mechine, the detaching rollers are set with pressure rollers (5d,6d), two ends of the pressure rollers athwartships to the rotating shaft of the separating roller are effected by a pressure device, characterized in that the separating rollers (5a, 6a) have column middle region, every condition of the two sides and the adjacentend is set with at least two continuous taper parts (K1, K2), the conicity of the rear taper (K2) is larger than the front taper (K1) in each condition seeing along the direction of the correspondingend of the separating rollers.

Description

technical field [0001] The invention relates to a detaching roller of a carding machine, on which pressure rollers are arranged, pressure means acting on both ends of the detaching roller transversely to the axis of rotation of the detaching roller. Background technique [0002] For separating and splicing operations on the carding machine, the lap ends previously carded by the carding section of the circular comb are transported by the clamping assembly to the following pair of separating rollers. The detaching roller pair is driven in a pilgrim-step, the previously formed fiber sliver (sliver for short) is conveyed back in a certain amount in the direction of the gripper assembly (gripper for short). In this case, the ends of the laps (fiber ears) that are conveyed and carded out by the gripper are placed at the ends of the slivers that are conveyed back in partial quantities. The direction of rotation of the pair of detaching rollers is then reversed, so that the end of ...
