A heating press plate for a multilevel or multistage platen press is formed with passages, traversed by a heating fluid, e.g. superheated steam. According to the invention, these passages are formed by paired parallel bores with the bores of each pair being separated from one another by relatively thin partitions, webs or ribs, and the pairs of bores being separated by relatively thick partitions, walls or ribs, the bores of each pair being traversed by the fluid in the same direction while the bores of adjoining pairs are traversed by fluid in opposite directions. Connecting chambers bridge adjacent pairs of bores and the relatively thin partition is set back from the chamber to provide mixing zones in which the bores of each pair communicate with one another before they open into the respective chambers. |
