Abstract
A press die for producing a clay roof tile, including a first die half and a second die half, which can move between a pressing position, in which they define a receiving space that represents the form of the finished roof tile, and a filling position, in which they are mutually spaced and the receiving space can be filled with a plastically deformable clay material. At least one of the first and the second die half has at least one depression which represents a projecting part of the finished roof tile; a first compression element is provided at the depression, and movable between an initial position, in which it is retracted in relation to the form of the finished roof tile, and a compacting position, in which some sections of the first compression element represent the surface of the finished roof tile.
