    摘要： An apparatus and method for bending a printing plate is disclosed. A bending machine, in particular for the bending of printing plates which are used in printing machines, includes a pressure pad, which exerts the required clamping force on the printing plate during the bending operation, and which is movable in relation to a holding-down plate, so that a uniform clamping force acts on the printing plate over the entire length of the pressure pad.

    摘要： A plate cylinder has formed therein a groove extending parallel to the cylinder axis and having a depth direction thereof set at an angle to a plane tangent to the plate cylinder at the groove, so that the opposite sides of the groove are at acute and obtuse angles, respectively, to that plane. For use with this plate cylinder, the printing plate has two staggered series of spaced lugs formed on a pair of meeting edges of its image-bearing major part. The two series of lugs are bent at approximately the same acute and obtuse angles, respectively, to the major part as the opposite sides of the groove are to the tangential plane. For mounting the plate to the cylinder, the acute-angled series of lugs of the plate are first inserted in the groove in the cylinder so as to hook these lugs onto the acute-angled leading side of the groove. Then the plate is wrapped around the cylinder by rotating the same in a prescribed direction. Then the obtuse-angled series of lugs are inserted in the cylinder groove into an interdigitating relationship with the acute-angled series of lugs.

    摘要： Method of and apparatus for punching and bending a lithographic plate to match a particular press so that when the plate is subsequently mounted on that particular press, it is oriented to print a properly positioned image on a print surface. The method comprises the steps of (A) inspecting a plate at an inspection station to identify the plate and to determine the position of a registration mark on the plate, (B) comparing the position of the registration mark to a predetermined reference position, (C) identifying the particular press on which the plate is to be mounted, (D) determining whether the position of the registration mark on the plate is to be adjusted relative to the reference position to a compensating position to compensate for potential misalignment of the plate image on a print surface when the plate is mounted on said particular press, (E) positioning the plate at the inspection station in a final plate punching position in which the registration mark on the plate is either in the reference position in the event it is determined there is to be no compensating adjustment, or in said compensating position in the event it is determined there is to be a compensating adjustment, (F) punching the plate when it is in its said final plate punching position, and (G) bending the plate after it has been punched.

    摘要： To mount a lithoplate onto a plate cylinder of a conventional web press, the lithoplate is double crimped, a stiffener is fitted snugly between the two crimps, and the stiffener and crimped portion of the lithoplate are inserted into a longitudinal channel in a plate cylinder. The invention permits for the first time precision mounting of a lithoplate which has a stretchable base such as a polyester base. A stretchable lithoplate preferably is mounted over underpacking with which it has a high effective coefficient of friction.

    摘要： A bending jig for lithographic plates to provide precise bends in the leading edge and trailing edge thereof. The lithographic plate to be bent is supported on a plate support mounted in a support frame and a leading edge anvil and a trailing edge anvil are provided adjacent opposite ends of the plate support. Positioning means are provided for accurately positioning each lithographic plate in the jig in order that the bends may be made accurately and repetitively in lithographic plates. Bending bars are provided for moving in lithographic plate bending relationship to the leading edge anvil and trailing edge anvil to provide the bends in the plate required for mounting the plate accurately in the cylinder of an offset press.

    摘要： Exposed printing plates are bent in the area of a bending device to form a leading end and a trailing end. Each exposed and bent printing plate is grasped in the area of the bending device at the leading end or at the trailing end of the printing plate by means of a gripping bar and transferred together with the gripping bar to a transporting device. The transporting device transports the printing plate together with the gripping bar toward a printing press, where the printing plate is removed together with the gripping bar from the transporting device in the area of the printing press. While grasped by the gripping bar, the plate is transferred to a form cylinder of a printing mechanism of the printing press.
