Abstract: The invention is in the field of adhesive binding of sheet-form printed materials arranged in stacks and, in particular, is directed to a method and device of the type that cuts side edges of sheet-form printed materials with tool. According to various aspects of the invention, a tool having a cutting edge and a notching element is provided as well as a method of making the tool, and a method of changing a depth of notching by changing an angle of rotation relative to a cutting plane is described.

Abstract: A device for removing electric charges from flat or printed material that is transported through a feed channel made up from grounded metal plates, particularly for printed material on the conveyor of a printer or copy machine. At least one discharging mechanism situated approximately perpendicular to the transport direction of the printed material is disposed opposite the outer surface of the metal plates turned away from the feed channel, whereby the discharging devices are situated so that they are essentially opposite each other or staggered in the transport direction of the printed material. The discharging devices are made up of either passive means and/or active devices positioned approximately perpendicular to the transport direction of the printed material across the entire width of the feed channel.

Abstract: An apparatus for transporting and delivering individual sheets (14) within a final processing unit (11) downstream from a printing or copying unit (10). In the final processing unit (11) an input transport roller pair (15) is followed by a sheet transport track (18) having a stop surface (20) for lateral registration of the sheets (14) passing through, a working delivery surface (24) having a stop surface (22) for end-surface registration of the sheets (14) being arranged at the end of the sheet transport track (18). Arranged after the working delivery surface (24) is a final delivery container for the individual sheets or sheet stacks, which extends at a 90° angle to the sheet transport track (18).

Abstract: The present invention relates to the binding of signatures and in one of its aspects relates to a method and apparatus for binding a digitally printed product such as “books on demand” wherein the signatures used in the printed product are produced by a digital printer or the like and the spine element used in binding products of different thicknesses can be supplied from a single supply roll.

Abstract: It is a device for alignment of stock, such as a sheet of paper or a film, in the transport path of a printing machine, especially in the transport path between a storage container for the stock and the print station or the print station and finishing devices, such as stitching and binding devices and collecting or stacking containers.

Abstract: Apparatus for feeding strips coated with a fusion adhesive on one of their surfaces to a sheet-stack binding apparatus, in particular, for the binding of loose sheets to form brochures or books, such apparatus enabling, in parallel with a binding operation, a strip cut to the required length to be made available for a subsequent binding operation. The apparatus (14) arranged in the strip path downstream of a cutting unit (12) includes a transport carriage (15) which is stationary with respect to the strip path (13) and movable vertically to the strip path and on which a horizontally movable element (16) as well as a plurality of stationary mechanical elements (11, 17) are arranged for holding the strip free from torsion.

Abstract: A stapling device has a holddown element, a staple forming member, and a staple driving means, which are guided linearly and are movable perpendicular to the upper side of a sheet stack to be stapled.A first pressure spring with a lower spring force is associated with the holddown element. A second pressure spring whose spring force is greater than that of the first pressure spring, is associated with the staple forming member. A third pressure spring is associated with the staple driving means, its spring force being greater than that of the second pressure spring. The pressure springs are arranged with identical working directions perpendicular to the upper side of the sheet stack.The first pressure spring is arranged in preloaded fashion between the holddown element and the staple forming member. The second pressure spring is arranged in preloaded fashion between the staple forming member and the staple driving means.

Abstract: Method and apparatus for feeding strips having a fusion adhesive coating on one of their surfaces to an advancing transport unit, in particular a sheet-stack binding apparatus where loose sheets are bound to form brochures or books. The method is carried out in that a thickness range of a sheet stack to be bound is associated with a specific width of a strip coated with a fusion adhesive, in that the association is effected in that the thickness of the sheet stack to be bound is determined or in that a selectable predetermined value is provided and in that the sheet-stack thickness value preselected or determined is used to control a drive mechanism (5, 6) which transfers the strip associated with the thickness range of the sheet stack to be bound from separate standby positions (7') of a number of strips (1c, 1d) of different widths to a handling position (12').

Abstract: Control of the neutralization of surface charges existing on objects such as paper, fabrics, plastic sheets or the like. In order that the surface of an object (1) can be neutralized independently of the output parameters, the electrostatic charge present on the object (1) is determined by means of a charge sensor (2) arranged upstream of the brush. The charge already neutralized via the brush (5) is also continuously measured. The two values are fed to a microprocessor (11) causing an actuator (7) to control the brush-to-object distance. The controlled movement of the brush (5) effects complete neutralization.
