In the bookbinding device, a punching unit performs a punching process on a sheet; an aligning unit aligns a plurality of sheets on which holes are punched; and a ring binding unit mounts, in the holes of the sheets aligned by the aligning unit, a ring-shaped binding tool to create a booklet. A prohibiting unit, if a sheet received from the image forming apparatus is a punched sheet having a hole thereon, causes the punching unit not to perform the punching process on the punched sheet.

Abstract: A punching processing unit punches holes in a paper bundle delivered from a preprocessing device. A bookbinding unit includes a cartridge for stocking a plurality of rings, and performs a ring binding by binding the paper bundle with the rings. A detecting unit detects an abnormality of a ring in the cartridge. A control unit exchanges a signal with the preprocessing unit each time when detection information obtained by the detecting unit changes. When any one of the rings is determined as abnormal and an execution of ring binding is set, the control unit inhibits the ring binding.

The closing assembly includes a rail and a closing tool carried by and movable along the rail, and adapted to engage the spine binder for closing the spine binder over the sheath as the closing tool is moved along the rail.

Abstract: A current processing mode is judged. The current processing mode can be a first mode, in which both a punching process and a binding process are performed, and a second mode, in which only the punching process is performed. A paper unit spacing, which is an interval between a last sheet of paper in a preceding paper unit and a first sheet of paper in a subsequent paper unit, is set depending on the current processing mode. A paper unit spacing for the first mode is longer than a paper unit spacing for the second mode.

Abstract: A cutting tool (1) for a punching machine has a punching body (8) on which a plurality of punching tool elements (5) which are located parallel to each other are provided. The puncing body (8) consists of a double-layered metal sheet (2, 12). Essentially longitudinal openings (7) are advantageously punched out of a sheet metal plate (2 and 12) symmetrically about an axis (6), these longitudinal openings (7) being situated parallel to each other, respectively. The sheet metal plate (2, 12) is then folded about the axis (6) in order to form the double-layered punching tool elements (5). This allows the use of more simple punching machines and enables a punching machine to be produced from just a few individual parts.

Abstract: Deformable metallic or plastic connectors of the type having an elongated bridge carrying two mirror symmetrical rows of substantially C-shaped prongs can be assembled with successive stacks of overlapping sheets, wherein the spine of each stack is provided with a row of straight or arcuate holes, by causing the connector at an inserting station to move along an arcuate path extending transversely of the bridge and having a curvature corresponding to or approximating that of the prongs in one of the rows or that of the arcuate holes. This results in the introduction of one of the rows of prongs into the holes. The prongs of at least one of the two rows are thereupon deformed so that the tips of the prongs of one row abut or at least slightly overlap the tips of the prongs of the other row; this prevents accidental separation of the connector from the stack.

Abstract: A rectangular opening/closing bar is formed, which is inserted in the curl ring of the ring binder to bind papers. The tip end of the opening/closing bar 28A is provided with an instruction portion 28a to raise and open ring pieces in turn while inserting the opening/closing bar 28A. Further, the opening/closing bar may have swollen portions on both ends of the opening/closing bar 28A to enable the bar slide smoothly in the curl ring. And it may be provided with a guide plate 28D perpendicular to the side wall 28b of the opening/closing bar 28A of the swollen portions side. In order to enhance the workability of the opening/closing bar, it may be preferable to use an auxiliary device for positioning the ring binder.

The circular blade 1 is rotatably beard concerning an axis of rotation 27. At the circumference of the blade 1 cutting elements 2 are arranged. This cutting elements 2 raise over a fictive rolling circle 21. The surface of the counter die 19 is arranged perpendicular at the distance of the rolling circle radius rW to the axis of rotation 27 of the circular blade 1 and show one or several opening in which in each case intervenes at least one cutting element 2 of the circular blade 1.

Abstract: An automatic feeding station (10) for receiving a plurality of binding elements (70), packaged in a continuous bandolier strip (74), and feeding same into an inserter station (12), for the automatic edge binding of a stack of sheets. The feeding station (12) comprises a housing consisting of a pair of vertically oriented end walls (14,16), and a pair of downwardly extending, angularly disposed walls (18, 20) converging at the bottom of the housing. A first such angular wall (18) defines the feed path for the bandolier strip (74) consisting of a pair of continuous plastic films (76, 78) joined at spaced apart intervals to define plural, laterally oriented pockets or cavities (80) to receive the binding elements (70) in a spaced apart, parallel relationship.

Abstract: The present invention is directed to a device for opening a binding element for receiving perforated sheets, the binding element comprising a spine and a plurality of relatively spaced ring elements arranged side by side, with the free ends of the ring elements resiliently engaging the binder spine when closed. A low-cost device for opening a binding element is provided. The device includes a front section, a rear section having at least the same length as the binding element and being dimensioned such that, when the device is inserted into the binding element, the ring elements successively come into contact with the outer areas of the rear section, and that the free ends of the ring elements are spaced at least up to a specified distance from the spine, and a curved surface area provided at least in the rear section and being partly engaged by the inner surfaces of the ring elements.

Abstract: Successive stacks of overlapping paper sheets are delivered by tongs to an assembling station where the sheets of successive stacks are connected to each other by circular binders including rims having a T-shaped or an L-shaped cross-sectional outline and being receivable in T-shaped or L-shaped marginal recesses of the sheets. The binders are delivered into and are held in the form of a row in equidistant sockets provided in part in stationary and in part in movable supports at the assembling station. Portions of sheets of a stack at the assembling station are deformed against the adjacent binders to thus introduce the binders into discrete recesses of each sheet, and the thus obtained stationery products are removed from the assembling station longitudinally of the row of sockets.

Abstract: An improved method and apparatus enable automated assembly of loose-leaf books, preferably photo albums from snap-ring binders of the slant D configuration and pages with peel-back overlays on mounting sheets. The apparatus comprises: a binder conveyor adapted to position a binder at an assembly station such that an upstanding segment of each ring in open position extends upward and has a vertical projection smaller than that of the holes in the pages; a page support positioned above the binder conveyor and having openings therein adapted for alignment with the holes in the pages; and a binder lift mechanism adapted to vertically lift a binder such that a segment of each ring is moved through the openings in the page support and the holes in the pages supported thereby. The process is automated and employs two linearly moving conveyors which intersect to enable positioning the binder with open ring elements at the assembly station.

Abstract: In a binding machine for binding packets of perforated sheets together by means of pronged wire binding elements, the elements being fed as an open pronged binding strip from a toothed wheel to a toothed feed chain along a path, the strip being guided between the wheel and chain by a guide having guide surfaces which converge so that the open prongs of the strip are guided without deformation of the strip between the wheel and chain no matter what size of strip is being fed.
