ABSTRACT:
A heater for a double facing apparatus includes a flat metal plate where channels are drilled through end faces of the plate. Slots are provided at the end faces of the plate to interconnect pairs of adjacent channels at alternate ends to form a serpentine steam passage through the plate. The channels are positioned through the plate proximate to the upper surface of the plate, to define a thin web of plate material between the channel and the upper surface and a thick web of material between the channel and the lower surface of the plate. End caps are welded over the slots to seal the communication between the adjacent interconnected pair of channels. Steam supply ports extend into the serpentine path to steam pressurize the serpentine passage. Air vents can be supplied between some adjacent channels of the heater, extending between an upper and a lower surface of the plate. These air vents can be used to present air pressure to the lower side of the heater to lift the paper off of the heater, or can be used to present a vacuum to the board to draw the paper against the heater.
