Abstract

A wrinkle or misaligned winding caused in a separator roll is inhibited. In a slitting apparatus (), a conveying direction of a first separator () is changed to a first take-up roller (U) side by a direction changing roller (), the first separator is conveyed via a take-up assisting roller () which is provided between the direction changing roller and a first touch roller (U) so as to shorten a roller-to-roller distance to the first touch roller, and the first separator which is being wound is pressed onto a take-up surface by the first touch roller.
