ABSTRACT:
A double facer platen is constructed so as to utilize a liquid heating medium which flows through a chamber containing a labyrinth defining a flow passage whose cross-sectional area decreases in the direction of flow from an inlet toward an outlet. The platen is adapted for use with liquids which have a temperature in excess of 400.degree. F. and a pump pressure of about 50 psi. The platen is supported by a beam having a temperature control means for compensating for any temperature difference between the upper and lower plates of the platen.
