ABSTRACT:
Two conveyors and a cutting device are employed to prepare and cut folded articles from plastic sheet material. The first conveyor has a conveying run for advancing a sheet of foldable plastic material, and the second conveyor has a conveying run which is positioned above the first conveyor conveying run and which extends for a length of the first conveyor conveying run. A first end of the second conveyor run is positioned intermediate of upstream and downstream ends of the first conveyor conveying run and is spaced a distance from the first conveyor conveying run. The cutting device is positioned above the first conveyor conveying run at a position intermediate of the first conveyor conveying run downstream end and the second conveyor first end for cutting a sheet of plastic material advanced lengthwise on the first conveyor conveying run so that a portion of a width of the sheet between side edges is separated from the sheet. The remainder of the sheet from which the portion has been cut is taken up by the second conveyor conveying run and which is driven to advance and recede from the first end and the sheet advanced on the first conveyor conveying run is folded over onto itself prior to the cutting.
