DRIVING METHOD AND MECHANISM FOR ROLL MANUFACTURING DEVICE

PROBLEM TO BE SOLVED: To control driving rotation for a roll manufacturing device with very high precision by external operation. SOLUTION: This driving mechanism which drives the driving shift 16 of a roll manufacturing device takes as one cycle the following: an acceleration time period capable of controlling acceleration time and acceleration with acceleration rotation started by carrying current from the rotation stopping condition where current does not flow, a constant speed time period capable of controlling so that constant-speed rotation can continue based on the time and the rotational speed set with the constant-speed rotation started by the completion of the acceleration time, a deceleration time period capable of controlling deceleration time and deceleration with deceleration rotation started by the completion of the deceleration time, and a rotation stopping condition during the time when current does not flow, starting by the completion of deceleration time, and repeats the cycle a plurality of times to drive the rotation of the driving shift 17. The acceleration time period, constant-speed time period, the deceleration time period, and the rotation stopping condition can be set by external operation in advance.
