Abstract
A wrinkle caused in a separator roll is inhibited. A slitting apparatus () changes a conveying direction of a first separator () by a direction changing roller () toward a first take-up roller (U), and conveys the first separator via an assisting roller () which is provided between a take-up position of the first separator to be wound and the direction changing roller so as to shorten a conveying distance between the take-up position and a roller immediately before the take-up position.
