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 feedhead is valveless and has a vacuum applied thereto during the entire feed cycle in order to increase reliability and decrease minimum feed speed. The top vacuum corrugation feeder includes fluffer jets and vectored auxiliary fluffer jets in order to assist the air knife in separating severely downcurled sheets for feeding.
