Embodiment Construction

[0040] figure 1 Shown is the rotatable carrying roller 1 of the measuring station 2, the sleeve 3 accommodated on the carrying roller and the sleeve 3 accommodated on the sleeve 3, preferably by means of an adhesive tape 4 (or alternatively by means of a glue coating of the sleeve) on A printing plate 5 fixed on the sleeve 3 (the so-called “mounter”), at least with respect to its relief topography, is a cross-section of the aforementioned individual components of the rotor 6 . Alternatively, preferably laser-scribed embossing sleeves can be measured on a carrier cylinder.

[0041] In order to rotate the carrier roller 1 during the measurement, a motor 7 can be provided in the measurement station 2 . The measuring station 2 can be part of a so-called "setter" in which the printing plate 5 is mounted on a carrier sleeve, or it can be provided separately and independently from the "setter". Measuring station 2 can be arranged independently of printing press 8 , which is provid...

Abstract

The invention relates to a method for measuring a surface (14) of a rotating body (6) configured for a cylinder (15), roller (15), sleeve (3) or printing plate (5) of a printing press (8) A device for a raised portion (13) of, for example, a flexographic printing plate, comprising a first motor (7) and a measuring device (18) for rotating a rotor (6) around an axis of rotation (22), the device being characterized in that , the measuring device (18) comprises at least one radiation source (19) and at least one area camera (21) for contactless measurement. Preferably, the measuring device (18) further comprises a reference object (30) for contactless measurement, for example a wire tensioned axially parallel; and a second motor (29) and if necessary a further second motor (29b ) for enabling adjustment of the measuring device (18) and / or the reference object perpendicular to the axis of rotation (22). The device enables fast and highly accurate measurement of raised features, such as flexographic printing dots.

Description

technical field [0001] The invention relates to a device for measuring a crown of a surface of a rotating body. [0002] The invention is based in the technical field of the graphic industry and here in particular in the field of measuring rotating bodies such as cylinders, rollers, sleeves (preferably laser-scribed flexographic printing sleeves), or printing plates (preferably is a flexographic plate mounted on a sleeve). The bulge of the rotating body is detected during the measurement. Background technique [0003] Document DE3302798A1 discloses a detection surface coverage Or the printing part and the non-printing part are combined with register presetting to shorten the setting time. [0004] The document DE 10 2014 215 648 A1 discloses a rotary printing press with a central counter-pressure cylinder rotatable about an axis of rotation; at least one (preferably several) printing layers (Druckdeck) surrounding the central counter-pressure cylinder An arrangement whe...
