Abstract: In addition to removing noil from a combing machine, the lap pieces which occur during a lap change operation are suctioned off and recycled into the combing process so as to reduce the amount of waste generated by the combing process. The noil and lap pieces can be removed from the combing heads through a common suction tube and conveyed separately via connecting pipes to separate points. The lap pieces which have been separated can be transported into a drum separator with the fiber material of the lap pieces being separated and recycled for the production of new laps.

Abstract: The nipper unit comprises a lower nipper as well as a an upper nipper and an auxiliary nipper, the latter two each being movable with respect to the lower nipper between a closed position and an open position. The auxiliary nipper is spring-loaded against its closed position. If the upper nipper is in its opened position, the auxiliary nipper is in its closed position and is used to tightly clamp a lap on a lower nipper plate while a previously combed fiber tuft is detached therefrom. When the upper nipper moves to its closed position, stop elements arranged on the upper nipper come into contact with stop surfaces arranged on the auxiliary nipper and open the auxiliary nipper so that the lap on the lower nipper plate can be advanced. The timing of the opening of the auxiliary nipper is determined by the position of the stop elements on the upper nipper.

Abstract: The combing machine comprises a continuously rotatable circular-comb cylinder carrying a circular-comb segment and detaching segment. The detaching segment cooperates with a detaching pressure roll. The combing machine also contains a nipper unit comprising a lower nipper which is stationary relative to the axis of the continuously rotatable circular-comb cylinder, and an upper nipper which is movable relative to the lower nipper. The fibers detached by the detaching segment together with the detaching pressure roll are sucked as fiber clusters into a suction shaft or tube, or can be united to form a sliver at a rotatable screening or sieve drum. The suction shaft includes a flexible membrane to close the shaft. The combining machine is of simple construction and economical to manufacture and renders possible a high operating speed and, therefore, a higher output, particularly in the absence of a top comb between the lower nipper and the detaching pressure roll.
