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.
