This greatly simplifies once again the installation of the rolling plate in the continuous press. On the one hand, there is considerably more space at the back of the rolling plate, so that the connection between the heating channel and the heating system in the continuous press remains unaffected. considerably easier to carry out. On the other hand, an interference of the surface hardness is excluded by the inventive arrangement and since the terminals are arranged vertically, dirt can not deposit on them so well, which reduces the risk of fire.
