ABSTRACT:
A sheet separating apparatus is designed so that tension is applied to a continuous sheet having weakened lines arranged thereon at predetermined distances so that the continuous sheet is separated along the weakened lines. The sheet separating apparatus comprises first and second conveying mechanisms spaced from each other and adapted to transfer the continuous sheet and to increase tension on the continuous sheet along the course of transfer thereof, and a guide roller for maximizing the increased tension at a predetermined position in the continuous sheet, thereby starting separation of the continuous sheet at that portion of each weakened line which corresponds to the predetermined position.
