Abstract
A sheet processing apparatus includes a folding device to fold a sheet and a fold-enhancing device to press a folded portion of the sheet folded by the folding device to perform enhanced folding processing on the sheet whose trailing edge has exited the folding device.
Claims14
A sheet processing apparatus comprising:
- a folding device to fold a sheet;
- and
- a fold-enhancing device to press a folded portion of the sheet folded by the folding device to perform enhanced folding processing on the sheet whose trailing edge has exited the folding device,
A sheet processing apparatus comprising:
- an overlay device to overlay a plurality of sheets sent sequentially and form a sheet bundle, the overlay device including a holder branching from a sheet conveyance path, and the overlay device to convey a preceding sheet in a predetermined direction, subsequently convey the preceding sheet in a direction opposite to the predetermined direction, and hold the preceding sheet in the holder;
- a folding device to fold the sheet bundle sent from the overlay device;
- and
- a fold-enhancing device to press a folded portion of the sheet bundle folded by the folding device to perform an enhanced folding processing on the sheet bundle whose trailing edges have exited the overlay device.

A sheet processing apparatus comprising:
- an overlay device to overlay a plurality of sheets sent sequentially and form a sheet bundle, the overlay device including a holder branching from a sheet conveyance path;
- a folding device to fold the sheet bundle sent from the overlay device, the folding device including:
- a conveyor to convey the sheet bundle;
- a reversible conveyer rotatable in reverse to convey the sheet bundle conveyed from the conveyer;
- and
- a folded portion former to form a folded portion on the sheet bundle;
- a fold-enhancing device to press the folded portion of the sheet bundle processed by the folding device to perform enhanced folding processing;
- and
- circuitry to:
- control the overlay device, the folding device, and the fold-enhancing device,
- control the reversible conveyer to convey the sheet bundle held by the conveyer and the reversible conveyer to the conveyer, bend the sheet bundle, and enter a bent portion of the sheet bundle into the folded portion former to fold the sheet bundle,
- control the overlay device to convey a preceding sheet to the folding device by a predetermined amount in a predetermined direction, subsequently convey the preceding sheet in a direction opposite to the predetermined direction, and convey the preceding sheet to the holder to hold the preceding sheet in the holder, and
- control the fold-enhancing device to perform the enhanced folding processing on the sheet bundle after a trailing edge of the sheet bundle has exited a portion of the folding device that works to convey the preceding sheet into the folding device when the overlay device overlays a plurality of sheets.
