Abstract: An embossing press designed to enable embossing, for example, a sender's name and address in customary reading location respectively separately selectively on letter writing paper sheets and on envelop flaps is provided with unique die plate carrying means enabling easy removal of the opposed die holders each with its individual die plate and replacement of them in horizontally reversed position. Each of the die plates is mounted in the terminal slot in its respective spring leaf or arm of a double-armed spring die holders carrier, both arms of which are joined at their inner end integrally to a yoke, by means of which the spring die holders carrier is attached rigidly firmly yet removably (when needed) to the supporting base of the press.
