Abstract
A heating device for corrugated cardboard comprises a heating member which is formed by a heating plate consisting of a rectangular plate having side walls, front and back walls integral with the plate and a lower or bottom surface of the plate is connected to a sheet of deformed steel having a small thickness to present cells or passages which are obtained by deformation. The front and back borders of the sheet of steel have been folded at 45.degree. angles so as to form a front chamber and a back chamber that act as manifolds for the flow of fluid in the passages. The heating member is connected in a floating manner to a rigid sub-frame by means of rods, and the whole sub-frame and member are also connected in a floating manner to the main frame of the machine that produces the corrugated cardboard.
