Abstract
The invention relates to a flat bed embossing machine (1) comprising a tool plate (20) with a tool side (36) for receiving at least one embossing tool and with a tool plate rear side (35) which lies opposite the tool side (36), further a base plate (10) with a tool plate side (12) which faces the tool plate rear side (35) and with a base plate rear side (11) which is lies opposite the tool plate side (12), for transmitting an embossing force which is exerted upon the tool plate (20), between the tool plate side (12) and the base plate rear side (11), as well as an induction heating appliance (3) for heating the at least one embossing tool (23). The induction heating appliance (3) comprises an inductor (16), the design of which and its arrangement between the tool plate side (12) and the base plate rear side (11) being such that a magnetic alternating field (19) which on the tool plate side (12) reaches beyond the base plate (19) and is for the inductive heating of an inductively heatable tool plate (20) can be produced beyond of the tool plate side (12) and outside the base plate (10).
