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. The drive arrangement may also include a motor that directly drives the roll core. The chucks driving the roll core may further be adaptable to variably support various roll core diameters and may include structures for positively gripping the core.
