ABSTRACT:
A heating plate, especially for presses utilized to bond two belt ends together, e.g. in the formation of an endless conveyor belt or in the repair of a conveyor belt. According to the invention, the heating effect over the plate which is rectangular or of rhombic configuration, is held uniform by distinguishing between longitudinal edge zones, transverse edge zones, central zones and corner zones, all of which have essentially the same specific volume of material, i.e. the same volume of material with a unit area of the heating surface. A frame work of longitudinal and transverse edge members of the same cross section and intermediate members parallel to the longitudinal edge member and equidistant from one another is sandwiched between a heating plate and a cover plate and the heating elements lie adjacent the heating plate in the spaces between the longitudinal and intermediate members.
