Abstract
A heating device of a two-sided machine has a stand which has a first arcuate hot plate and a wall on which a sleeve is provided. A second arcuate hot plate is arranged above the first arcuate hot plate. The second arcuate hot plate is connected to the sleeve by a connecting stem. The stand includes a cylinder unit, the piston rod of which is connected to the trailing end of the second arcuate hot plate. A second corrugated-cardboard ply and a first corrugated-cardboard ply are guided so as to run between the hot plates, whereas a third corrugated-cardboard ply is guided so as to run, above the second arcuate hot plate, through the second arcuate hot plate. The second arcuate hot plate is lowered by the cylinder unit in order to be placed in connection with the second corrugated-cardboard ply.
