Extrusion molding apparatus

Abstract

To provide an extrusion molding apparatus that molds a resin film using a T-die method, which allows easy adjustment of a film thickness of the resin film.SOLUTION: An extrusion molding apparatus that extrudes molten resin from a lip opening 152 formed by opposing a movable lip 115 of a first block and a fixed lip 116 of a second block to be molded to a film shape, comprises: a plurality of studs 121 fixed at tips to the movable lip and provided on the first block; a plurality of actuators 122 capable of advancing and retracting the studs by rotational motion of a motor; a plurality of detectors for detecting an operating status of the motor included in each actuator; and a controller advancing and retracting the studs corresponding to each actuator, wherein the controller generates a correction control amount for a second stud adjacent to a specific first stud in accordance with a detection result of the detector when advancing and retracting the specific first stud, and advances and retracts the second stud based on the correction control amount.SELECTED DRAWING: Figure 2
