摘要

PROBLEM TO BE SOLVED: To provide a pull-out device for a web folded in a zigzag form without causing deterioration of quality and cut-off. SOLUTION: A pair of entrance guides 15 is arranged for supporting the fold or its vicinity of the web 11 at its either front end so that the web can be pulled out of a space between the pair of entrance guides 15. A pair of movable guides 17 supported by a spring 18 are provided in the downstream thereof. The tension variation of the web is reduced by moving the movable guides 17 with the tension of the web 11 and the fluttering of the web is reduced by arranging a pair of exit guides 20 on the downstream thereof.
