ABSTRACT:
A hot press mechanism for a printing machine includes a roller having a longitudinal channel and a peripheral chamber formed in the peripheral portion. A mold piece is secured on the peripheral portion of the roller for engaging with a sheet material to be printed. A heating plate is engaged in the peripheral chamber of the roller for heating the mold piece, and a heat insulating layer is engaged between the roller and the heating plate for preventing the roller from being heated. Only the mold piece is heated for allowing much electric energy to be saved.
