SILVER FEEDING APPARATUS FOR AN OPEN-END SPINNING DEVICE

摘要

Mechanism for supplying sliver to a resolving roller is adaptable to slivers having different average staple fiber lengths by selectively engaging a plurality of clamping members to provide a selectable nip line between a sliver supply roller and its cooperating member at different distances from the resolving roller corresponding to the sliver average staple length. Either the selected clamping member or the counter member is the supply roller. Selection of the desired nip line may be made by moving one or more clamping members and the counter member relatively, by selection of one of a plurality of feed nozzles, or by selective positioning of a movable feed nozzle. The nip line selection may be effected at individual spinning stations or simultaneously for a plurality of spinning stations.
