摘要:
An spine formation device includes a sheet conveyer that conveys the bundle of folded sheets in a sheet conveyance direction with a folded portion of the bundle forming front end portion thereof, first and second sandwiching units disposed downstream from the sheet conveyer, a contact member disposed downstream from the second sandwiching unit, against which the folded portion of a bundle of folded sheets is pressed, and a controller. The controller stops the sheet conveyer after the bundle is transported a predetermined distance from a contact position between the contact member and the folded portion of the bundle, causing the bundle to bulge, and causes the first and second sandwiching units to squeeze the bulging of the bundle of folded sheets in a thickness direction sequentially with the folded portion of the bundle pressed against the contact member to form a spine of the bundle.

A spine formation device includes a sheet conveyer, a presser, and a spine formation member. The sheet conveyer conveys a bundle of folded sheets with a folded portion of the bundle of sheets forming a front end portion of the bundle of sheets. The presser is disposed downstream from the sheet conveyer in a sheet conveyance direction in which the sheet conveyer conveys the bundle of sheets. The presser is movable to press opposed sides of the front end portion of the bundle of sheets. The spine formation member is movably disposed downstream from the presser in the sheet conveyance direction. The spine formation member includes a groove portion that contacts and positions the bundle of sheets to define an amount by which the bundle of sheets protrudes from the presser and a spine formation face that forms a spine at the folded portion of the bundle of sheets.

A bookbinding system that includes: a center folding unit configured to perform center folding on an integrated sheet bundle; an additionally folding unit configured to additionally perform folding of a folded portion of the center-folded sheet bundle; a back surface forming unit configured to form a back surface on the sheet bundle by pressing a front end of the folded portion of the center-folded sheet bundle and both surfaces of the sheet bundle; and a control unit configured to change the content of additionally folding according to whether to perform the back surface forming or not.
摘要:
An spine formation device includes a sheet conveyer, a contact member including a first row of grooves provided in a contact surface thereof to house a projection projecting from a folded portion of a bundle of folded sheets, a driving unit to move the contact member, first and second sandwiching units to squeeze the bundle, a discharge unit, and a controller. The first row of grooves extends in parallel to the folded portion of the bundle and includes at least a first pair of grooves inclined in different directions with an interval therebetween varying in size with location of the grooves in a first direction perpendicular to a sheet conveyance direction. The contact member is moved to change the size of interval between the first pair of grooves at a position aligned with the projection projecting from the folded portion of the bundle of folded sheets.

A spine formation device includes a sheet conveyer, a clamping unit disposed downstream from the sheet conveyer in a sheet conveyance direction, for squeezing a folded portion of a bundle of folded sheets, a contact member against which the folded portion of the bundle is pressed, disposed downstream from the clamping unit, and a controller to cause the bundle of folded sheets to bulge by stopping the sheet conveyer after the bundle of folded sheets is transported a predetermined conveyance distance from a contact position between the contact member and the folded portion of the bundle and to cause the clamping unit to squeeze a bulging portion of the bundle created between the sheet conveyer and the contact member with the folded portion pressed against the contact member. The predetermined distance is set in accordance with a predetermined sheet-related variable.

A conveying device that conveys a sheet bundle with a flattened back-face portion includes a first conveying unit, a driving unit, and a second conveying unit. The first conveying unit retracts to a position where no driving force is exerted on the sheet bundle before a leading end of the sheet bundle formed in a flat spine shape enters, and abuts on the sheet bundle to exert conveying force after the leading end of the sheet bundle passes a conveying position. The driving unit moves the first conveying unit to retract to the position and to abut on the sheet bundle. The second conveying unit is positioned on an upstream side of the first conveying unit in a sheet bundle conveying direction and conveys the sheet bundle towards the first conveying unit.
