ABSTRACT:
An original roll positioning device sets a position of an end face of a new roll at a predetermined reference position. An end pull-out device sucks and pulls out the leading end of the new web from the positioned new roll at a predetermined length. A pair of roll-up chucks of an end roll-up device holds both sides of the leading end of the pulled-out web, and the roll-up chucks are rotated to roll up the leading end of the web at a predetermined length. A suction box sucks the web at a part between the roll up chucks and the roll, and then a cutter cuts the web along the width of the web to form a splicing part. The splicing part is sucked by the suction box, and the spliced part is made to wait in this state until the start of the splicing operation.
