A compartment which is operatively connected with a negative pressure source and formed in a hood or cover member, surrounds the infeed connection and is bounded by the pressure or compaction rolls in the direction of travel or feed of the sliver. The mouthpiece flow communicates with the compartment by means of openings provided at its circumference, and between these openings and the inner surface of the mouthpiece there are formed guide surfaces.</p> |
