A conveying mechanism (11) conveys a mater material (M) along a first conveying path (11A) and then downwardly along a second conveying path (11B) while holding the material (M) between first and second conveyor belts (20, 30). The second conveying path (11B) oscillates about a fulcrum defined by a downstream point (23A) on the first conveying path (11A). A reciprocating mechanism (70) causes a substantially horizontal reciprocating motion of the discharge end of the mat material (M) from the second conveying path (11B), and also imparts a force which urges the discharge end in the reverse direction to accelerate said discharge end on reversal. In this manner, the collection of cotton takes place evenly across the folded area of the piled-up material, to provide an even surface density over the entire piled-up material (M), thereby increasing the effective width and reducing the amount of edge trimming from the folded areas. <IMAGE> |
