The sliver condensing station for drawn sliver to be fed to a spinner has a sliver clamping action at the final drawing rollers and a clamping roller at the end of the suction zone with structured pressure springs acting on the rollers

摘要

The apparatus to condense a drawn sliver, for a spinning machine, has an air-permeable transport belt to carry the sliver from the final drawing rollers over a sliding surface with a suction slit. The sliver is held firmly at both ends of the condensing zone by the upper roller (8) of the final pair of drawing rollers, and a clamping roller (19). Pressure springs (23,24) act on the drawing roller (8) and the clamping roller (19) for the required clamping forces on the sliver passing through. The spring (23) at the final drawing roller (8) exerts a force which is a multiple of the force applied by the spring (24) at the clamping roller (19). The clamping roller (19) drives the sliver transport belt (12). The clamping roller (19) is powered by the final pair of drawing rollers (3). The clamping roller (19) is mounted to a holder (25), which swings on an axis (26) coaxial to the axis of the final drawing roller (8).
