<p>The present invention is directed towards an apparatus (17) for guiding continuous materials (18). In one embodiment of the invention, the apparatus comprises first and second conveyors (12, 14), each comprising a continuous conveyor belt (20, 36) carried by a set of pulleys including a drive pulley (22, 38) and an idler pulley (24, 40). The conveyor belts have opposing inner surfaces (25, 27) that are oriented to travel substantially parallel to one another to sandwich continuous materials therebetween. The ratio of the diameters of the idler pulleys to the drive pulleys is greater than about 8:1. In another embodiment of the invention, a chopper (16) is provided. The chopper comprises a cutting roll (70) and a cot member (77) defining a nip region (N) therebetween. The cutting roll has an axis of rotation that is aligned substantially parallel to an axis of rotation of a cot member. The small turning radii permit the conveyor belts to extend within the nip region.</p> |
