Abstract
A technique of controlling a cutter-blade pressing force to be a constant force even in employment of a configuration improving a production efficiency of a pellet is provided. In a resin cutter, a controller configured to control the cutter-blade pressing force is configured to variably control each of a revolution number of a rotation shaft attached to a cutter head, a magnitude of a rotation-shaft forward force Ff and a magnitude of a rotation-shaft backward force Fb so that the cutter-blade pressing force is constant.
