Web transfer apparatus

A web transfer apparatus comprising:

• an unwinding section configured to unwind a web wound into a roll-shape;
• a transfer roller section configured to transfer the web on a predetermined web transfer path;
• a wind-roller section configured to change a transfer direction of the web by winding the web;
• a cutter arranged on the downstream side of the arrangement position of the wind-roller section on the web transfer path, and configured to cut the web in units of regular sizes;
• a web transfer control section configured to drive-control the unwinding section, transfer roller section, wind-roller section, and cutter;
• and
• a roller moving mechanism configured to change the arrangement position of the wind-roller section in such a manner that an interval between the wind-roller section and cutter becomes a length offset from a length of an integral multiple of a length of a cut sheet cut in units of the regular sizes.
