摘要： PROBLEM TO BE SOLVED: To inhibit the gap between edges at the ends in a length direction when forming a paper tube having M character-like insertion sections at both sides. SOLUTION: After a sheet 1 is folded up into a twofold from the center section to a width direction and both end edges F1 and F2 in the width direction are bonded to form a flat paper tube 5 before forming M character-like insertion sections 2 and 3, the M character-like insertion sections 2 and 3 are formed at both sides in the width direction of the paper tube 5. Since end edges F1 and F2 in the width direction folded up into a twofold are bonded together before forming M character-like insertion sections 2 and 3, the end edges F1 and F2 in the length direction of the sheet 1 are correctly faced together, and these end edges F1 and F2 can be bonded together.
