ABSTRACT:
A press plant includes a press of pressure cell type, into which a tray device, which defines a space intended to receive a workpiece and, optionally, a forming tool, is insertable. The tray device comprises a tray plate and a tray frame. The tray frame is adapted to independently withstand, at least in certain portions, loads applied during the pressing operation. The tray device is divisible into at least an upper part and a lower part. The invention also relates to a method and use of a tray device in a press plant.
