Abstract
Fiber slivers must be condensed during the course of a spinning process or their mass must be determined. For this purpose there are employed so-called grooved pairs of rollers, that is to say, profiled rolls which define a sliver throughput groove which is limited or confined at both sides. The sliver is guided through a feed or delivery funnel up to the throughput groove. The danger thus exists that individual fibers can jam between the side surfaces or faces of the rollers which form the lateral boundaries of the groove. This danger is eliminated with the invention in that the fiber outlet opening of the feed funnel is located within the region of a wedge-shaped gap which is bounded by an overlapping zone of the side surfaces or faces of the rollers.
