Deformation device with a machine frame on which a pair of tools is arranged, wherein one of the tools is arranged on the machine frame so as to be relatively movable along a movement path and the tools form a size-variable working gap and wherein a first optical safety device is assigned to the movable tool, the safety device comprises a first beam source to provide a first beam bundle parallel to the end surfaces of the tools and a first light receiver to receive the first beam bundle wherein a second optical safety device is assigned to one of the tools, the second optical safety device comprises a second beam source to provide a second beam bundle and a second light receiver to receive the second beam bundle to secure a side surface of the tool aligned normal to the movement path and bordering on the end surface.

A uniaxial press for shaping pellets by compressing powder in a die by punches. The uniaxial press can be used in a restricted and hostile environment and includes small modules that can pass separately through narrow openings, the modules being assembled by placing over columns and by screwing, therefore by remote handling in the confined space where the press is to operate without requiring any further intervention. The actuation is generally exclusively electromechanical.

The present invention relates to a block machine (1) with a machine bed (2, 3) at which at least one lifting device (4, 5) for a supporting member (6, 7) is arranged. The supporting member (6, 7) is movably supported on the machine bed (2, 3) via a linear guide which has at least one longitudinal guiding member (8a, 8b, 9a, 9b) and a guiding means (10, 11, 12, 13, 14, 15) interacting therewith. To the supporting member (6, 7) there is attached a first longitudinal guiding member (8a, 8b) that is movably supported via at least one bed guiding means (10, 11, 12, 13) that is arranged at the machine bed (2, 3). At the machine bed (2, 3) a second longitudinal guiding member (9a, 9b) is arranged on which the supporting member (6, 7) is movably supported by a supporting member guiding means (14, 15) arranged thereon.
