Abstract
In an apparatus on a spinning room machine for depositing fiber sliver, a stationary delivery device for delivering fiber sliver and a substantially flat receiving support surface for receiving and collecting the fiber sliver as a can-less fiber 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 fiber 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.
Claims22
An apparatus on a spinning room machine for depositing fibre sliver, comprising:
- a sliver delivery device;
- a substantially flat receiving support surface for receiving and collecting fibre sliver delivered by the delivery device, the receiving support surface being substantially unenclosed;
- a drive arrangement for driving the receiving support surface back and forth between first and second reversal points during sliver deposition;
- a path along which the receiving support surface is driven comprising opposed first and second reversal paths, the reversal paths being separated from one another by a further, traversing path portion, and
- a control device to control the receiving support surface at a traversing speed along the traversing path portion, the control device adapted to alter the speed of the receiving support surface at an end of the traversing path portion and at a beginning of the first or second reversal path, wherein the control device gradually brakes the receiving support surface from the traversing speed in a falling sinusoidal or cosinusodial progression to a speed value of zero at the first or second reversal point, and wherein the control device gradually accelerates the receiving support surface from zero in a sinusoidal or cosinusoidal progression to the traversing speed after the receiving support surface traverses the first or second reversal point.
