Abstract
Disclosed herein is a high release nip roll assembly comprising a nip roll with a covering comprising a high release material. The release properties of the nip roll material can permit intermittent contact without the coating adhering to the surface of the roller and wrapping the nip. Also disclosed is a high release nip roll belt made of a high release material on the top and bottom surfaces of the belt. The belt can be positioned at each end of a nip roll so that areas of the nip roll typically vulnerable to molten thermoplastic material contact are protected by a belt. Also disclosed is a belt making apparatus. Also disclosed is a frame assembly for moving a belt longitudinally along a nip roll. Also disclosed is a rope guide assembly for threading a belt in relation to a nip roll and at least at least one belt roller. Also disclosed is a jig for joining a leading section of a belt and a trailing section of a belt.
