Abstract
A continuous material feed device is provided with a motor driving a continuous material feed mechanism, and transfers a continuous material into a press intermittently. Its control device is provided with (1) a position detector for detecting position of the continuous material feed mechanism, and (2) a control circuit for (a) fixing and storing previously the optimum pattern command value of behavior of the continuous material feed mechanism, (b) calculating error between the real position data from the position detector and the fixed command value of the optimum pattern in a prescribed period of time from the drive start of the continuous material feed mechanism, (c) correcting the command value to be output in order to eliminate the error (d) outputting the command value after the correction (e) controlling the motor.
