摘要 |
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.
