ABSTRACT:
There is described an apparatus for bundling a drafted roving (4), comprising a rotating conveying surface (3) provided with air through-holes (6) succeeding each other in direction of rotation (9), and comprising a suction means connected to the conveying surface (3) on the side facing away from the roving (4) in the vicinity of the air through-holes (6), which suction means forms a slot-like suction zone (5) for the roving (4) extending in direction of rotation (9) of the conveying surface (3). To create advantageous constructional conditions, it is proposed that the suction zone (5) should have at least one suction slot tapering in direction of rotation (9) of the conveying surface (3) from at least two rows of holes to one row of holes.
