Abstract
PURPOSE: To perform smooth operation of feeding a sheet by reel, by providing at least two brakes in the core shaft of a feeding roll and controlling them in such operation that one of the brakes in arranged to linearly change its brake torque, further brake torque of the other brake in operation is saturated to the maximum value.
CONSTITUTION: At least two brakes 9-1, 9-2 are parallely built in to a core shaft 3 of a feeding roll 1 and constituted in such a manner that the breake 9 and the brake 9-2 are applied. At successively feeding operation of the roll 1 at a constant speed and at feeding operation on the way of feeding under rapid speed deceleration respectively. In this way, throughout the whole process of feeding operation from the beginning in a state of maximum diameter to the end in a state of minimum diameter, smooth work of feeding a sheet can be performed while applying constant tension to the sheet.
