Japanese Patent JP7271279
Kind Code:
B2
Abstract:
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.
