Embossing tool for a plate press, comprising an inner cylindrical element (3) with an external groove (9), which extends over the periphery of the element and is divided into four slanting and four axial groove sections (10, 11). The inner cylindrical element is surrounded by a sleeve element (2) which can be axially displaced relative to the inner element and has guide rollers (8) which engage in the groove (9). A guide sleeve (1) fixed in a lower part of the press surrounds the sleeve element and has axial slots (4) in which external guide rollers (5) on the sleeve element engage. Upon displacement of the sleeve element with the inner guide rollers in the slanting groove sections, the inner cylindrical element is turned a quarter of a turn. The return stroke with the guide rollers in the axial groove sections does not act on the inner sleeve element. The inner cylindrical element has raised areas (22) on its top surface, which are thus turned a quarter of a turn for each stroke the press makes. |
