摘要： In a sheet folding apparatus for folding a sheet, a sheet is pushed at a predetermined position thereof by a push member while the sheet is being conveyed by a conveyance roller. The predetermined position of the sheet is guided to the nip section of a folding roller pair. Then, the sheet is nipped at the predetermined position thereof and folded by the folding roller pair.

摘要： A sheet folding apparatus includes a folding roller pair that forms a first fold line owing to that the folding roller pair nips a first position of the sheet, which has a loop to be formed on an upstream side of the folding roller pair due to continuous conveyance of the sheet by a conveyance roller pair in a stopped state in which a front end of the sheet being conveyed from the conveyance roller pair is nipped by the folding roller pair, as starting conveyance of the sheet while a pushing plate is pushing the sheet and moving toward the folding roller pair, and thereafter, forms a second fold line owing to that the folding roller pair nips a second position of the sheet with the loop formed as aligning with a rear end of the sheet.

摘要： A sheet folding processing apparatus performs folding processing on continuously conveyed sheets without lowering productivity. A sheet folding processing apparatus includes a conveyance roller pair, a folding roller pair forming a plurality of fold lines by bending a sheet conveyed from the conveyance roller pair in Z-shape, an additional folding roller and a lower folding guide arranged downstream of the folding roller pair to face each other and pressing the fold line of the sheet in corporation with each other, and a controller controlling operation of the above. The controller controls the folding roller pair to convey the sheet with the fold line downstream in a conveyance direction until the fold line passes through the additional folding position by a predetermined conveyance amount, to return the sheet upstream by reversely rotating the folding roller pair, and to position the fold line to the additional folding position for additional folding processing.
