Abstract
A top vacuum corrugation feeder includes articulating suction fingers to assist in raising the top sheet of a stack of sheets to the feedhead of the vacuum corrugation feeder. The suction fingers are rotated down from their interleaved position between feed belts to contact the top sheet in the sheet stack and raises the top sheet to the feed belts. As a result, the feeder can handle heavy sheets, curled sheets, and sheets which are edge welded.
