Abstract
In an apparatus on a spinning room machine for depositing fibre sliver, a stationary delivery device for delivering fibre sliver and a substantially flat receiving support surface for receiving and collecting the fibre sliver as a can-less fibre sliver package are present. The receiving support surface, which is substantially unenclosed, is movable during the depositing process back and forth in the horizontal direction by a drive arrangement. In order to improve the production of the can-less fibre sliver package, the speed of the receiving support surface with the sliver package is alterable substantially on a reversal path such that a gradual braking to speed value zero to the speed of the back and forth movement are effected.
Claims23
An apparatus on a spinning room machine for depositing fibre sliver, having:
- a sliver delivery device;
- a substantially flat receiving support surface for receiving and collecting fibre sliver delivered by the delivery device, the support surface being substantially unenclosed;
- and
- a drive arrangement for driving the support surface back and forth between first and second reversal points during sliver deposition;
- wherein the path along which the support surface is driven comprises opposed first and second reversal paths separated from one another by a further, traversing path portion along which the support surface is arranged to travel at a traversing speed, and on reaching an end of a traversing path portion and entering a reversal path the speed of the support surface is alterable such that a gradual braking to the speed value zero and a gradual acceleration from the value zero to the traversing speed are effected.
