ABSTRACT:
A roll-to-roll paper web feeding system for a laser printer. The paper web is unwound from a roll supported in the unwind machine by a single conveyor belt driven at a speed that varies to match the web feed to the speed of the printer. A pivotably mounted beam houses the belt and can be raised to permit replacement of the roll. A shock absorber acts between the beam and the machine frame to maintain contact between the belt and the paper roll. Replacement of the belt is facilitated by a unique latch acting on the support shaft for a sprocket at the free end of the beam provided for the belt. The paper web is rewound on a roll provided in the rewind machine. Tension must be kept high enough in the paper web to assure a tightly wrapped roll in the rewind machine. This fact requires a friction, or drag roller, to maintain at least one free loop of web, and this drag roller can be replaced quickly as a result of shifting it laterally to decouple the coupling provided at one end of the drag or friction roller. The rewind machine has an exposed straight run of web material across the top of the pivoted beam that carries the driven roller member. A printer and/or slitter is provided on this beam for slitting the web material and/or printing on selected portions of the web.
