Fiber strand i.e. carbon fiber strand, widening device, has input-sided part provided for fiber strand and output-sided part for widened volume, and two rotation-symmetric widening surfaces arranged with respect to pivot axis

摘要

The device has a fiber strand (68) i.e. carbon fiber strand, detached by a distracting device from a supply in a distracting direction (D). An input-sided guiding part (56) is provided for a fiber strand and an output-sided guiding part (58) is provided for the widened volume. Two rotation-symmetric widening surfaces (36) are arranged with respect to a pivot axis parallel to the distracting direction, where the widening surfaces forms a gliding surface arched convex in the distracting direction for the fiber strand and are reciprocatable opposite to each other around the pivot axis.
