Abstract: The combing machine has at least one comber head which contains a continuously rotatable comb cylinder, a reciprocating nipper jaw unit and at least one detaching roller. The detaching roller is rotated during every revolution of the comb cylinder at first through a small angle in a backwards direction and then through a large angle in a forward direction. The rotations of the detaching rollers are produced by an electric motor which receives appropriate drive pulses fed from an electronic control unit.

Abstract: The drive mechanism for the feed roll of a combing machine employs a freewheel having an inner member secured to the feed roll and a concentric outer member secured to the pivotal arm which mounts the top nipper. In addition, locking elements are disposed between the inner and outer members and the outer member provided with a sawtooth configuration so that the locking elements may lock during rotation of the outer member under the influence of the arm and may move into a released position during an opposite rotation of the outer member. The lost motion or idle travel in the changeover between the released position and the locking position is quite reduced. Thus, feeds are always of substantially exactly the same magnitude with a resulting improvement in the produced sliver.

Abstract: A combing machine for textile fibres has a gill for combing a sliver of fibres, and at least two contrarotating tearing rollers for tearing successive tufts from the sliver of fibres as these are combed, the torn tufts being partially superimposed on each other to form a continuous combed web which is delivered to a conveyor belt. The tearing rollers are in direct contact with each other and are located upstream of the conveyor belt.

Abstract: An intermittent drive revolving clearer for drafting rollers that moves to avoid the motion of a top comb thereby permitting continuous cleaning of the drafting rollers resulting in high efficiency cleaning and improved yarn quality. A knife edge removes the waste material from the continuous clearer cloth without mixing the clearer waste material with the sliver, thereby permitting continuous operation of the clearer for long periods of time.
