Abstract:

A system and method for forming fluted polymer boards and recycling scrap material. A feeder feeds polymer to an extruder, which extrudes fluted board stock from the polymer. A scrap portion of the board stock is separated from another portion that comes to form the boards. The recycling system returns the separated scrap portion along a return path to the feeder and forms holes in the scrap portion creating fluid communication between the flutes and atmosphere before the scrap portion is returned to the feeder. The scrap portion can, in some embodiments, be ground into granular form after being hole-punched without creating a pressure condition in the flutes that adversely affects extrusion of the board stock.
