A sheet processing apparatus comprising: a scoring unit which scores a sheet; a folding unit which folds a sheet bundle including a plurality of sheets; a pressing unit which presses a folded part of the sheet bundle folded by the folding unit; and a controller which determines, based on information on the sheet bundle, whether the scoring unit scores the sheet included in the sheet bundle to be folded and whether the pressing unit presses the folded part of the sheet bundle.

A sheet processing apparatus includes a pressing unit and a shifting unit. The pressing unit has a protrusion and presses the protrusion against a fold section of a sheet. The fold section extends in one direction. The shifting unit moves at least one of the protrusion of the pressing unit and the sheet so as to shift a pressing position, at which the fold section is pressed by the protrusion, in the one direction or in a direction opposite to the one direction.

A sheet processing apparatus includes a folding unit, a fold reinforcing unit, and a control unit. The folding unit folds a sheet and forms a fold line thereon. The fold reinforcing unit includes a fold reinforcing roller. The fold reinforcing roller sandwiches the fold line on the sheet formed by the folding unit and moves in a fold-line direction in which the fold line extends. The control unit moves the fold reinforcing roller from a first position close to a first end of the fold line on a first side in the fold-line direction to a second position close to a second end of the fold line on a second side opposite to the first side. The control unit can execute, at this time, a division movement mode including a reversal return operation. The reversal return operation is an operation of reversing a movement direction of the fold reinforcing roller to the first side at a middle portion of the fold line and then returning the movement direction of the fold reinforcing roller to the second side.

A collapsed adhesive tape tube dispenser for dispensing adhesive tape rolls. The dispenser having a baseplate having a first end, a second end, and a baseplate center line extending longitudinally in the machine direction. A tape roll unwind supported by the baseplate near the first end. A mandrel extending in the machine direction having a mandrel first end and a mandrel second end with the mandrel second end being cantilevered and unsupported. An exterior forming die positioned between the first end and the second end, and the exterior forming die having a shaping portion with a threading slot. A compression roller located near the second end for flattening the adhesive tape tube structure.

A winding device for formation of fibrous rolls includes: a first conveyor and a second conveyor; a movable compression roller which delimits a winding area with guide surfaces of the conveyors; a movable pre-compression conveyor including an upstream roller, a downstream assembly with a curved downstream end, and a belt wound around the upstream roller and the downstream assembly. The belt is held under tension against the downstream assembly and forms, facing the guide surface of the first conveyor, a circulating pre-compression surface for pre-compression of a fibrous mat to be wound, the pre-compression surface being a pre-compression element closest to the winding area.

A sheet conveying apparatus includes a sheet conveying path through which a sheet is conveyed, and a burr pushing portion provided on the sheet conveying path and pushing down a burr, formed at one side edge in a width direction orthogonal to a sheet conveying direction of the sheet, in the width direction. The burr pushing portion includes a contact portion coming into contact with the burrs while inclining with respect to the side edge of the sheet conveyed thereto.

Provided is a sheet processing device capable of preventing a folded sheet bundle from being opened after pressing to improve accumulating property and aligning property of the sheet bundle. A sheet processing device B that presses a folded sheet bundle includes a pair of pressing rollers 70 that press a fold of the folded sheet bundle in a thickness direction of the fold, a pressing roller unit 56 that moves the pressing roller pair 70 along the fold of the folded sheet bundle, and a cam member 80 that regulates an interval between the pressing roller pair 70. When the pressing roller unit 56 is moved along the fold of the folded sheet bundle to press the fold in the fold thickness direction, the cam member 80 reduces stepwise the interval between the pressing roller pair 70 in accordance with a moving direction of the pressing roller unit 56.

A folding processing device includes a pressing section that includes a first opposing member and a second opposing member, the first opposing member opposing a folded portion of a folded sheet, the second opposing member opposing the first opposing member with the folded portion interposed therebetween, the pressing section pressing the folded portion by nipping the folded portion by using the first opposing member and the second opposing member; and a guiding section that is disposed upstream from the pressing section in a sheet transport direction, the guiding section nipping the sheet whose folded portion has passed through the guiding section and guiding the sheet to the pressing section.

An enclosing device to insert an enclosure into an envelope conveyed to an enclosing position includes an envelope conveyor and an enclosing unit. The envelope conveyor conveys the envelope to the enclosing position. The enclosing unit opens a frontage of the envelope such that the enclosure is inserted into the envelope that has reached the enclosing position and includes an opening amount adjuster to adjust an opening amount of the frontage when the enclosure is inserted into the envelope. The opening amount adjuster adjusts the opening amount, depending on a flap length and a body length. The flap length is a length of a flap of the envelope in a conveyance direction in which the envelope is conveyed to the enclosing position. The body length is a length of a body of the envelope in the conveyance direction.

A sheet processing apparatus includes a processing unit, a braking mechanism, and, a damper mechanism. The processing unit is movable to a drawn-out position and an accommodated position. The drawn-out position is a position where the processing unit is drawn out from the sheet processing apparatus. The accommodated position is a position where the processing unit is accommodated in the sheet processing apparatus. The braking mechanism acts to brake the processing unit in a case where the processing unit is inserted in a direction from the drawn-out position toward the accommodated position at a speed equal to or higher than a predetermined speed. The damper mechanism absorbs an impact on the braking mechanism in a case where the braking mechanism act, by applying a load to the processing unit moving in the direction from the drawn-out position toward the accommodated position.
