Abstract: An apparatus for compacting a fiber sliver on a spinning machine, has a carrier which has a receptacle for a bolt. A rotatably mounted suction drum has a closed end face and an open end face. A bearing element is disposed in the region of the closed end face. The suction drum is rotatably mounted on an end section of the bolt by the bearing element so that the bolt protrudes out of the open end face of the suction drum. To permit assembly and/or disassembly of the suction drum during the entire running time of the compaction apparatus, the suction drum is affixed axially by means of the bearing element with the bolt, as seen in its axial direction, so that the suction drum and the bolt form a separate unit of the apparatus. A fastening means by means of which the bolt is releasably fastened in the receptacle is provided.

Abstract: A cone mounted coaxially on a hand held motor. The cone has an open slot arranged to permit sliding a lock of hair through the slot. The lock wraps around the cone thereby forming a roll of hair when the motor is energized to rotate the cone. The cone is then separated from the roll and the hair is secured in place by a pin. A clamp/hook on the apex of the cone is provided to engage the free end of a lock of hair, a twist of hair (akin to a cable) is formed when the cone is rotated.
