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.
