Abstract
According to an embodiment, a sheet folding apparatus comprises a first roller, a second roller configured to be energized to the first roller, form a nip section together with the first roller, fold a sheet in half together with the first roller through the nip section and convey the sheet folded in half together with the first roller and a pressing force adjusting mechanism configured to be capable of increasing and decreasing a pressing force generated at the nip section. The pressing force adjusting mechanism causes a pressing force in a state of being conveying the sheet folded in half to be lower than that in a state of being folding the sheet in half.

A sheet folding method, comprising:
- preparing a first roller;
- preparing a second roller that forms a nip section together with the first roller;
- folding a sheet in half together with the first roller and the second roller through the nip section;
- conveying the sheet folded in half together with the first roller and the second roller;
- adjusting a pressing force generated at the nip section so as to cause the pressing force in a state of conveying the sheet folded in half to be lower than that in a state of folding the sheet in half;
- switching a relative position between the first roller and the second roller by a cam;
- and
- rotating the cam and the first roller coaxially.
A sheet processing method, comprising:
- discharging a sheet conveyed from a conveyance path;
- preparing a first roller;
- preparing a second roller that forms a nip section together with the first roller;
- folding a sheet in half together with the first roller and the second roller through the nip section;
- conveying the sheet folded in half together with the first roller and the second roller;
- adjusting a pressing force generated at the nip section so as to cause the pressing force in a state of conveying the sheet folded in half to be lower than that in a state of folding the sheet in half;
- switching a relative position between the first roller and the second roller by a cam;
- and
- rotating the cam and the first roller coaxially.
