ABSTRACT:
In an apparatus at a spinning preparation machine for changing sliver cans, sliver is delivered by a delivery device and deposited in a sliver can. The apparatus comprises means for moving a full sliver can away from the region of the delivery device and means for subsequently bringing in an empty sliver can, from a reserve position to the region of the delivery device. An intermediate storage device is arranged to be brought in to the delivery device during changing of the sliver cans is provided. In order to avoid disadvantageous piling up of the sliver on the intermediate storage device and/or in the sliver can and to allow can changing at maximum sliver production speeds, the immediate storage device is arranged to be driven such that it is movable whilst collecting the sliver.
