Abstract: A sheet processing apparatus includes a conveyance unit configured to convey a sheet, a creasing unit configured to form a first crease and a second crease different from the first crease on the sheet, and a detection unit configured to detect a direction of the first crease. When the second crease is to be formed after the formation of the first crease by the creasing unit, a direction of the second crease with respect to a widthwise direction of the sheet is controlled based on a detection result of the detection unit.

Abstract: A printing system includes a control unit configured to control an image forming unit to form an image on a sheet based on print setting information included in received job setting information, control a post-processing unit to execute a post-process corresponding to a designated type, and control a creasing unit.

Abstract: To provide a sheet processing device that performs saddle stitching processing that binds a bundle of stacked paper sheets at a position around a center thereof and then folds in half the paper sheet bundle at the binding portion, the device being capable of selectively performing both saddle stitching using a metallic staple and saddle stitching not using the metallic staple for environmental protection and capable of reducing a size.

Abstract: A sheet cutting apparatus includes a cutting unit configured to cut a sheet, a discharge unit configured to discharge a fragment of the sheet cut by the cutting unit, a blowing unit configured to blow air on the fragment discharged from the discharge unit, and a storage unit configured to store the fragment discharged from the discharge unit.

Abstract: A sheet post-processing device includes a stacker for stacking and storing sheets therein, a feeder for receiving sheets and feeding the sheets toward the stacker, a folder for folding a set of sheets stored in the stacker, a preparatory processor, which is located upstream from the folder, for processing sheets preparatory to folding of a set of sheets, a presser for pressing the set of sheets stored in the stacker at a portion processed by the preparatory processor so as to push the set of sheets into the folder, and a controller for controlling the stacker, the feeder, the folder, the preparatory processor and the presser. The controller controls the preparatory processor not to process a sheet that will be an outermost sheet of a folded set of sheets.

Abstract: A sheet finishing apparatus includes a punch unit to punch a sheet, and a saddle unit to bundle and to fold the sheets. A position and an inclination angle of a puncher are changed according to a skew amount of the sheet, the puncher is controlled to form punch holes in the sheet at positions symmetric with respect to a folding line, and punching is performed so that an interval between the folding line and the punch hole becomes small at the inside of a bundle of the sheets and becomes large at the front cover side.

Abstract: An apparatus and method provide for automated converting of a web of a thin patterned catalyst-coated membrane to separate membrane sheets for fuel cell assembly. The membrane typically has a thickness of about one thousandth of an inch. Automated web converting involves transporting, with use of a movable vacuum, an end portion of the membrane web from a first location to a second location. With use of respective first and second vacuums at the first and second locations, and after removal of the movable vacuum, the end portion of the membrane web is releasably secured at the first and second locations. The membrane web is cut within a gap defined between a single catalyst pattern of the membrane web end portion and an adjacent catalyst pattern to produce a membrane sheet. The membrane sheet is precisely positioned to a desired orientation to facilitate subsequent processing of the membrane sheet.
