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 air knife includes a pair of trapezoidal shaped fluffer jets that enable high speed feeding of 13# to 110# paper with one pneumatic setting while at the same time improving reliability and expanding stack height latitudes.
