PROBLEM TO BE SOLVED: To perform breaking-in operation of an embossing tool directly in a paper processing machine and at the same time, significantly shorten time for manufacturing the recessed shape of a female mold with the use of a hard embossing die by heating a counter tool and/or the embossing die. SOLUTION: An embossing die 33 with a projecting emboss motive is matched with a support face 32 and both are tightly clamped with a screw. Next, a counter tool 45 is assembled into the interior of a groove 44 in a lower-position embossing roll 6. This counter tool 45 is made of a thermoplastic plastics of viscotenacious elastic material and is of such a structure that an outwardly curved smooth surface 45' corresponds to the outer peripheral face 40' of a roll body. The surface 45' is heated by a hot blast air blower. Further, an upper-position embossing roll 5 is brought into contact with the lower-position embossing roll 6 while heat continues to be supplied, and these rolls 5, 6 are simultaneously rotated to move to stamp the projecting embosses motive on the surface 45'. Thus the recessed shape of a female mold is manufactured. The rotating movement is continued until the surface 45' is cooled ad the recessed shape of the female mold is endurably formed.
