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.
Claims26
A sheet processing apparatus comprising:
- a folding device to fold a sheet;
- 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, a trailing edge of the sheet having exited the folding device;
- and
- circuitry to control the fold-enhancing device to perform the enhanced folding processing on the sheet, and to control the folding device to fold a next sheet while the circuitry controls the fold enhancing device.

A sheet processing apparatus comprising:
- a folding device to fold a sheet;
- 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, a trailing edge of the sheet having exited the folding device;
- an overlay device to overlay a plurality of sheets sent sequentially, to form a sheet bundle, and to convey the sheet bundle to the folding device;
- and
- circuitry to control the folding device and
- to control the overlay device to receive a sheet subsequent to the plurality of sheets, before a trailing edge of the sheet bundle exits the folding device.

A sheet processing apparatus comprising:
- a folding device to fold a sheet;
- 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, a trailing edge of the sheet having exited the folding device;
- and
- an overlay device to overlay a plurality of sheets sent sequentially, to form a sheet bundle, and to convey the sheet bundle to the folding device,
- wherein a sheet conveyance direction, in which the sheet bundle folded by the folding device is conveyed to the fold-enhancing device, is opposite to a sheet conveyance direction in which the plurality of sheets are sent to the overlay device.
2 more elements
A sheet processing apparatus comprising:
- an overlay device to overlay a plurality of sheets sent sequentially and to form a sheet bundle, the overlay device including a holder branching from a sheet conveyance path, and the overlay device being configured to convey a preceding sheet in a direction, and to subsequently convey the preceding sheet in a direction opposite to the direction, and to 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, trailing edges of the sheet bundle having exited the overlay device.
