Abstract
A method for tightening an embossing plate ring on a chuck of a rotary embossing press, wherein the chuck is intended to be connected to a heater for leading the embossing plate ring to a working temperature. Between the chuck and the embossing plate ring is a split transmission ring made of a material having an expansion coefficient which is higher than that of materials used for the chuck and the embossing plate ring to cause the blocking of the embossing plate ring onto the chuck at the working temperature of the embossing plate ring.
