ABSTRACT:
A combing machine comprises a rotating combing roller with a comb segment, a feed device for a sliver to be combed, a gripper arrangement disposed in the vicinity of the comb segment which opens and closes in a manner coordinated with the passing movement of the comb segment and which holds the sliver while the latter is being combed by the comb segment, and a draw-off device which moves the combed sliver away. For reducing the mass to be moved and for the improvement of the combing quality a transfer gripper arrangement (14) is provided which is movable back and forth between the gripper arrangement (1) and the draw-off device (2) in a manner coordinated with the rotating motion of the comb segment (8) and which, after passage of the comb segment (8) and combing of the protruding tuft (22) and the opening of the gripper arrangement (1), grips the combed sliver (22) and holds it in such a way that during the next pass of the comb segment (8) the rear portion of the sliver (22a), looking in the direction of movement, is combed by the comb segment (8), and which then hands off the sliver 922) to the draw-off device (2).
