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.
