Abstract
A controller for winding an unvulcanized rubber sheet suitable for the formation of tires, transmitting belts and the like comprises a cylindrical drum rotated by a motor for winding the unvulcanized rubber sheet thereon, a conveyer for feeding the unvulcanized rubber sheet on the drum, a data processor for calculating a ratio of peripheral velocities of the drum and the feeding conveyer and a feeding quantity of the unvulcanized rubber sheet on the basis of previously inputted data and a sequence control unit responsive to an output of the data processor for controlling the sequence of operation of the movable portions of the controller, i.e. the sequence according to which each element of the controller for winding the unvulcanized rubber sheet and the motors are operated, which sequence is established according to a predetermined order.
