发明名称 APPARATUS FOR AIR-LAYING FIBRE BODIES ON A MOVING AIR-PERMEABLE CONVEYOR PATH
摘要 The present invention relates to an arrangement for air-laying on a moving air-permeable conveyor path (2; 7; 12) fibre bodies that have a profiled cross section transverse to the movement direction (A) of the conveyor path, wherein the arrangement includes at least one air-laying unit having means for delivering a stream of air-carried fibres to a region above the moving conveyor path; means (3; 8; 13, 14) for subjecting the stream of air-carried fibres in the delivery region to a subpressure beneath the whole of that part of the conveyor path located in the delivery region; and means (4; 5; 9, 10) for delimiting the stream of air-carried fibres from ambient air. According to the invention, the means for delimiting the stream of air-carried fibres includes at least one part (b; 9) which coacts with the air-permeable conveyor path and which has smaller dimensions transverse to the direction of movement than the air-permeable conveyor path.
