ABSTRACT:
A conveying mechanism 11 conveys a mat 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 reversal direction to accelerate said discharge end on reversal. In this manner, the collection of cotton takes place evenly across the folded areas of the piled-up material M, thereby increasing the effective width and reducing the amount of edge trimming from the folded areas.
