ABSTRACT:
A feeder for feeding corrugated blanks in a box finishing machine including overlying and underlying endless timing belts sandwiching the blanks to feed them. The belts are spaced from each other to form a first gap at rectilinearly moving sections located between opposite end pulleys of the belts. The gap between the belts at the inlet and outlet pulleys is greater than the first gap whereby blanks are engaged and fed by the belt sections as they move rectilinearly between the opposite end pulleys. One of the belts is urged into yieldable engagement with the blank by a pressure mechanism including a floating pressure plate engaging the belt and a spring engaging the pressure plate. An extended stroke feeder is used to feed blanks to the endless belts at a constant velocity matched to the velocity of the belts.
