Abstract

The invention relates to a device to condense and guide a fiber sliver, in particular in a spinning plant preparation machine having a sliver funnel. The funnel is followed by draw-off rollers which are surrounded on both sides by guide surfaces. The lateral distances between the guide surfaces and the draw-off rollers can be adjusted independently of each other. A process is also provided according to which the distance between the guide surfaces is selected to be greater for puffed fiber material than for non-puffed fiber material. Furthermore, the distance between the guide surfaces is selected to be greater with synthetic fiber material than with natural fibers.
