Abstract
A sliver guiding assembly for the passage of a sliver bundle discharged in a sliver advancing direction by output rolls of a drawing unit forming part of a draw frame. The assembly includes a sliver guide having a wall face converging in a direction of the advancing direction and a passage provided in the wall face. The sliver bundle is adapted to travel through the passage in the advancing direction. A sliver leading element is disposed upstream of the passage as viewed in the advancing direction for gathering the sliver bundle and for guiding it toward the passage. An arrangement is provided for maintaining communication between a zone of the sliver guide and enviromental air; the zone is defined between the outlet of the sliver leading element and the inlet of the passage.
