PURPOSE:To provide a controller for an inflation film manufacturing machine which can perform a stabilized manufacture of a film of a preset thickness by simplifying the constitution without using a metering hopper and controlling only a haul-up speed. CONSTITUTION:A pinch roll revolution sensor 6 which generates as many pulse signals as those corresponding to the number of revolutions of pinch rolls 4, a wind-up revolution sensor 9 which detects revolutions of a wind-up part of a wind-up machine 8 which winds film which has been hauled-up by the pinch rolls 4, and generates signals at every specified revolution are provided, and an operation means 10 of the film thickness and a pinch roll motor control means 20 are provided. |
