ABSTRACT:
A top vacuum corrugation feeder employs a vacuum feedhead working in conjunction with an air knife to feed sheets from the top of a stack. The vacuum feedhead includes a vacuum plenum with a plurality of perforated feed belts entrained around it. The feed belts have a diamond shaped knurl pattern on their sheet engaging surfaces in order to obtain a higher pressure differential across the sheet material during sheet acquisition.
