20090016850 | Bookbinding Unit and Image-Forming System - Bookbinding unit that, in feeding cover sheets to a predetermined cover-fitting position, is able to feed various sheets/leaves, yet without defacing of or scratch marks in the cover sheets, nor press marks during cover formation, occurring. Provided are an incoming sheet conveyance path for sequentially bringing in printed sheets; a stacking tray unit for stacking and collating into bundles sheets from the conveyance path; a bookbinding process path that transports sheet bundles from the stacking tray unit to a predetermined cover-binding position; and a cover feed path for feeding cover sheets to the cover-binding position. A protective-sheet storage tray for supplying jacketing sheets is annexed to the cover feed path, and a conveyance unit that overlays fed cover sheets with jacketing sheets from their storage tray and transports the jacketed cover sheets to the cover-sheet binding position is disposed in the cover feed path. | 01-15-2009 |
20090035093 | Bookbinding Method, and Bookbinding Unit and Image-Forming System Equipped with the Same - Bookbinding unit that in binding an inner-leave sheet bundle together with a cover enables accurate binding of the cover onto the bundle's spine and meanwhile forms folding scores in the cover flaps. Furnished with: a stacking tray unit; a process path for sequentially transporting bundles from the tray unit into adhesive-application and cover-binding locations; an adhesive application unit, disposed in the adhesive-application location, that applies adhesive to bundles from the tray unit; a cover-supply unit that supplies covers to the cover-binding location; and a cover-binding unit, disposed in the cover-binding location, that binds sheet bundles from the adhesive-application location together with covers. The cover-binding unit has a shoulder-pressing unit that forms spine creases in the spine portion of the covers, and a flap-pressing unit that forms folds in the spine-creased sides of the covers. | 02-05-2009 |
20090067951 | Bookbinding Unit, Bookbinding Method and Image-Forming System - Affords a bookbinding method and bookbinding unit that attach the bookmarker string when binding inner-bound sheets coated with adhesive on the spine portion to the spine portion of the coversheet. Apply adhesive to a spine portion of inner-bound sheets collated and stacked into a bundle, join that sheet bundle to a spine portion of a coversheet, and fold the coversheet over the sheet bundle. At that time, the bookmarker string is attached to the booklet simultaneously by joining the sheet bundle to the coversheet with the bookmarker string placed over the inside spine portion of the coversheet. | 03-12-2009 |
20090085271 | Bookmaking apparatus - A bookmaking apparatus includes: a first path for horizontally conveying a sheet bundle; a second path for vertically conveying a cover sheet; a joining stage for joining the cover sheet and sheet bundle; a gripping conveyance device at an upstream side of the joining stage for gripping and conveying the sheet bundle along the first path; and a folding conveyance device arranged at a downstream side of the joining stage for folding and conveying out the cover sheet and sheet bundle. The gripping conveyance device includes opening and closing clamping members for gripping the sheet bundle and clamping control device for opening and closing the clamping members. The clamping control device operates to vary a gripping position of the sheet bundle by the clamping members when joining the sheet bundle to the cover sheet at the joining stage and when conveying the joined sheet bundle to the folding conveyance device. | 04-02-2009 |
20090133619 | Adhesive Applicator and Bookbinder in Bookbinding Apparatus, and Image-Forming System Associated Therewith - Bookbinding-unit adhesive application device that does not interrupt the unit to replenish adhesive when consecutively applying adhesive to sheet bundles, and can shorten the time the system is interrupted. An adhesive storage container ( | 05-28-2009 |
20100202857 | BOOKMAKING APPARATUS - A bookmaking apparatus includes a first path to convey a sheet bundle, a second path intersecting the first path to convey a cover sheet, a joining stage disposed at an intersection of the first path and the second path, a gripping conveyance device arranged for gripping and conveying the sheet bundle along the first path, an adhesive application device for applying adhesive to a bottom side edge of the sheet bundle, a backup member arranged to support the cover sheet at the joining stage, and a folding conveyance device for folding and conveying the cover sheet and sheet bundle. After the cover sheet and the sheet bundle are adhered together and before the backup member retracts from the first path to a position outside the first path, the gripping conveyance device is retracted to separate a bottom edge of the sheet bundle from the backup member. | 08-12-2010 |
20110002755 | Bookmaking method - In bookmaking, a sheet bundle is held in a substantially vertical posture. At first an adhesive is applied to a bottom edge of the sheet bundle in a condition that the bottom edge of the sheet bundle and an adhesive application member are pressed together with a first contact pressure to apply the adhesive between the sheets. Then, the adhesive is applied to the bottom edge in a condition that the bottom edge of the sheet bundle and adhesive application member are pressed together with a second contact pressure weaker than the first contact pressure, or are in a non-contact situation. | 01-06-2011 |
20110222992 | Bookmaking Apparatus - A bookmaking apparatus includes a first path to convey a sheet bundle, a second path to convey a cover sheet, a joining stage disposed at an intersection of the first path and the second path, a gripping conveyance device arranged for gripping and a conveyance device arranged at a downstream side of the joining stage for conveying out the cover sheet and sheet bundle. The gripping conveyance device includes clamping members to grip the sheet bundle and clamping control device for opening and closing the clamping members. The clamping control device operates the clamping members to grip a lower edge of the sheet bundle when joining the sheet bundle to the cover sheet, and the clamping members to retract to an upstream side of the first path and to grip the sheet bundle again when conveying the joined sheet bundle to the conveyance device. | 09-15-2011 |
