Abstract: A machine for feeding rolls of web material to a utilization device that is adapted to draw the web material into the utilization device. The roll machine includes a frame carrying a carriage that supports a pair of arms having respective chucks that are adapted to move toward and away from each other for engaging and disengaging with the core of a roll that is being supported and fed. An overhead drive arrangement is used for driving the periphery of the roll in combination with a torque roller for maintaining tension in the web. A gravity loop of the material has its position sensed for control of the roll drive means in a manner to match the rate of use by the utilization device.
Abstract: A web feed system for a laser printer that controls the feeding of web through the printer to a receiving device. The system includes an input feed station and an output feed station. At the output feed station there is a shock absorbing support roller and a series of rollers including a torque roller that support the web in a detection loop. Several features are incorporated to permit ease of transition between box and roll feed states.
