Embodiment Construction

[0043] exist figure 1 A lithographic plate exposure apparatus 1 is shown in a cross-sectional view. The printing plate exposure device 1 is a semi-automatic device to which the printing plates 3 , 3 ′ are transferred manually via a printing plate transfer device 8 . For this purpose, the printing plate exposure device 1 has an input table 6 on the input side. For imaging the printing plates 3 , 3 ′, the printing plate exposure device 1 comprises an exposure cylinder 2 on which the printing plates 3 are clamped. To image the printing plate 3 , it is moved rotationally together with the cylinder 2 in the direction of the rotation arrow 5 and is imaged by an exposure mechanism 4 which can extend or move parallel to the axis of the exposure cylinder 2 .

[0044] In order to handle the supplied printing plate 3 ′ and the printing plate 3 clamped on the exposure cylinder 2 , the printing plate exposure device 1 has a printing plate receiving device 11 . The plate receiver 11 comp...

Abstract

A method and an apparatus for handling printing plates which are fed to at least two process stations, include at least one receiving deck on which the printing plates are provided and fed to the different process stations by pivoting the receiving deck. The receiving decks are pivoted first of all about a first rotational axis and likewise about a second rotational axis which is different than the first, in order to ensure favorable receiving angles between the receiving deck and the individual process stations in each case for the printing plate transfer. A printing plate exposer having an apparatus for handling printing plates, is also provided.

Description

technical field [0001] The invention relates to a method and a device for handling lithographic printing plates, wherein said lithographic printing plates are supplied to at least two processing stations, said lithographic printing plates being fed in at least one of the printing plate receiving devices Receiver plates are provided and the at least one receiver plate is oscillating about a first axis of rotation for conveying or transferring the printing plate from the first processing station to the second processing station. Background technique [0002] Before a printing form, for example a planographic printing plate (Druckplatte), is used in a printing process, such as offset printing, it must be imaged. To image these lithographic plates, an imaging device such as an outer cylinder exposure device, an inner cylinder exposure device or the like is used. [0003] For imaging, the lithographic plate is introduced into an imaging device. For this purpose, the printing pl...
