ABSTRACT:
An apparatus for registering substrates while they are partially in a turn baffle assembly. The apparatus includes a registration transport assembly and a turn baffle assembly having a pinch roller assembly. The pinch roller assembly includes a set of pinch rollers which feed the substrate through the turn baffle assembly and into the registration transport assembly. The pinch roller assembly also includes a motion inducing device for selectively moving one pinch roller away from the other and a low friction roller which is somewhat larger than one of the pinch rollers. The low friction roller is located near a pinch roller such that when the pinch rollers are moved apart, the low friction roller biases the substrate way from a pinch roller so as to reduce or eliminate friction between the substrate and that pinch roller.
