PURPOSE: To bring a sheet material to a nip according to this when the sheet material of a main roller lacks by arranging a balancing lever so as to be rotatable with a fulcrum as the center. CONSTITUTION: A towel delivered from a main roller 12 first passes through a nip between rollers 24, 26. Thus, before a sheet material enters the nip, the tip 44 of the towel coming out of a spare roll 14 is positioned on the under side of a tucking blade 34. When the sheet material of the main roller runs out, since balancing force by the main roller reduces, when the sheet material of the main roller completely runs out, the tucking blade 34 descends, and engages with the tip 44 of the towel to introduce the tip into the nip. Therefore, when the sheet material of the main roller completely runs out, the towel of the spare roll enters the nip. |
