Abstract: A method for cutting a lap in a comber includes applying pressure to a bobbin toward a lap roller. The method further includes forming a weak portion in the lap that is continuous from the bobbin to a nipper device in the state in which pressure is applied to the bobbin by pulling the lap toward the nipper device. The method further includes cancelling the applied pressure after forming the weak portion. The method further includes applying tension to the lap after forming the weak portion to cut the lap at the weak portion.

Abstract: A cleaner for a fiber bundle feeder, which nips and discharges a strip of fiber bundle with a top roller and a bottom roller, in a fore-spinning frame includes a support member located above the top roller and a tubular clearer having an inner diameter that is greater than an outer diameter of the support member. The tubular clearer is rotatable around the support member by the top roller such that the tubular clearer is located at a position where the tubular clearer is in contact with the top roller and a position where the tubular clearer is separated from the top roller. The tubular clearer is configured to block a fiber. A suction unit is configured to draw in the fiber that has been blocked by the tubular clearer.
