Abstract

Zum Transport und zum Lagern werden Druckplatten (2) in Kassetten oder auf Tabletts bereitgestellt. Sie sind dabei durch Zwischenlagen (3) voneinander getrennt. Zum Zuführen der Druckplatten 2 zu einem Plattenbelichter müssen diese zunächst vereinzelnd werden. Durch Adhäsion, Elektrostatik oder ähnlichem kann es beim vereinzeln zu einem sogenannten Multipicking kommen.For transport and storage, printing plates (2) are provided in cassettes or on trays. They are separated by intermediate layers (3). To feed the printing plates 2 to a plate setters, they first have to be singulated. Adhesion, electrostatics or the like can lead to a so-called multipicking.

Wenigstens zum Unterstützen des vereinzelns von Druckplatten (2) werden erfindungsgemäß in den wenigstens 2 obersten Druckplatten (2) eines Stapels (1) Wirbelströme (11, 12) mit gleichem Drehsinn induziert, durch welche die Druckplatten (2) voneinander abgestoßen werden.

Figure imgaf001
At least in support of the separation of printing plates (2), according to the invention, eddy currents (11, 12) are induced in the at least two uppermost printing plates (2) of a stack (1) with the same direction of rotation, by which the printing plates (2) are repelled from one another.
