ABSTRACT:
A drive assembly for first and second rolls in a roll laminator includes sprocket wheels affixed to each roll, a driven sprocket wheel, a first idler sprocket wheel rotatable about an axis, an endless drive element trained over the sprocket wheels, and a lever rotatably mounted on the axis of the first idler sprocket wheel. The first roll is carried by the lever for swinging movement toward and away from the second roll. The drive assembly is improved by the addition of a second idler sprocket wheel closely adjacent the first idler sprocket wheel, with the endless drive element also trained over the second wheel.
