Abstract:
1. 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.
