Abstract
The invention relates to a feed table for feeding slivers by way of a conveyor to a textile processing machine. The slivers are drawn off from associated spinning cans by way of draw-off devices and placed on the conveyor. In the event of a sliver running out or breaking, reserve slivers are fed in automatically by way of draw-off devices specifically devised for this purpose. The conveyor comprises individual conveyor belts associated with each sliver and each reserve sliver and have a draw-off devices, each conveyor belt being drivable by way of a controllable drive, the conveyor belts being a part of the draw-off devices.
Claims31
A feed table for continuously feeding slivers to a textile processing machine, comprising:
- (a) a plurality of sliver cans arranged in a row for supplying primary slivers to said textile processing machine;
- (b) a plurality of reserve sliver cans disposed adjacent to said sliver cans for supplying reserve slivers to said textile processing machine;
- (c) a first narrow flexible conveyor belt for each of said primary slivers, said conveyor belts being supported by a driven roller and an idler roller for conveying said slivers to a common delivery point;
- (d) a second flexible conveyor belt for each of said reserve slivers, said conveyor belts being supported by a driven support roller and an idler roller, adjacent to said first conveyor belt for alternately conveying said reserve slivers to said common delivery point;
- (e) first detection means for detecting the presence of each of said primary slivers and said reserve slivers, individually;
- (f) second detection means for detecting the absence of said primary slivers and said reserve slivers, individually;
- (g) a continuously driven common conveyor belt for receiving said slivers at said common point and for conveying said slivers to said textile processing machine;
- and
- (h) control means for receiving signals from said first and second detecting means, including means for selectively driving said driven rollers of said first and second conveyor belts to alternately deliver said primary sliver or its adjacent reserve sliver to said common point on said common conveyor, said control means commencing the delivery of a leading end of said reserve sliver to said common point at the same time that a trailing end of said primary sliver passes said common delivery point.
