Abstract

A device for the feeding and opening of a fiber sliver for an open-end spinning device, having a feeder roll, a pressure roll interacting with the feeder roll and an opening roll. The device includes a tray with two guide walls guiding the fiber sliver between the pressure roll and the opening roll and laterally between themselves. The pressure roll is mounted in the feeding tray which has a supporting surface between the feeding roll and the opening roll, to support the fiber sliver and which is delimited by the guide walls. The opening roll is driven in the same direction of rotation as the feeder roll.
