摘要: A drawing system in which a thickness and degree of orientation an oriented film or the like is maintained uniform manner under condition high speed, shortened time required from when molding material charged extruder started until taken up on take-up apparatus, quality produced at speed besides, probability for not-oriented to be broken down during reduced. are independently measured gauges measuring apparatus continuous after longitudinal lateral values input computer. The computer with respectively compares preset target control operation change draw ratio conducted if different respective based results comparison processing.
