The perforating wheels and the two backstop wheels are positioned on opposite side of the support table. The perforating wheels engage with the two backstop wheels through the two spaced apart openings. The endless feed belt has an upper portion and a lower portion. The lower portion of the endless feed belt is positioned above the support table. The protrusions on the lower portion of the endless feed belt engage with side stiffeners of the vent baffle sheet to move the sheet through the perforating wheels.
