Abstract
A feeder for sheets of material has belts for driving sheets through the feeder, and a gate above the belts to hold back the stack of sheets to be fed. The gate is elliptical in side elevational view and flat in front and rear elevational views. The major axis of the ellipse is disposed at an acute angle to the feed path, so sheets waiting to be fed engage the large-radius portion of the ellipse and are shingled just before reaching the position to be fed. The wide, flat surface has O-rings of rubber or the like to provide a high coefficient of friction for retarding the stack of sheets to be fed. A sensor detects a sheet that has been fed, and stops the feeder, so the feeder can be used as an on-demand feeder.
