A copper plating layer 14 is provided along the substantially wave-shaped heat receiving surface.
In addition, a wear-resistant layer 15 is formed on the heat dissipation surface of the upper plate portion 11 by nitriding treatment.

A corrugating machine double-sided machine using the hot platen apparatus S of the present invention will be described.
First, the single-sided cardboard is composed of a laminate of liner paper 1 and corrugated paper 2, and is transported with the corrugated paper 2 in the lower position.
And the gluing part that attaches the adhesive paste to the wave surface of the corrugated paper 2 includes a tank that stores the adhesive paste, a gluing roll that contacts the wave surface, a gluing roll that contacts the gluing roll, The presser roll is in contact with the liner paper 1.

  Then, the backer portion for bonding the back liner paper 3 to the wave surface of the single-sided cardboard is provided with a guide roll 4 for guiding the back liner paper 3 to be applied to the corrugated paper 2, and a heat that allows the back liner paper 3 to be slidably contacted. It is comprised from the board | substrate apparatus S, the belt conveyor 5 (canvas belt) contact | abutted to the upper liner paper 1, the presser roll 6 contact | abutted to the action part upper surface of this belt conveyor 5, and a cooling part.

  The hot platen device S of the present invention includes, for example, a steel plate rectangular plate-like upper plate portion 11 having a relatively thick thickness, and a steel plate-made rectangular plate-like lower plate arranged in parallel to the upper plate portion 11.

First, in the glued portion, adhesive glue is attached to the wavefront of the corrugated paper 2 of single-sided corrugated cardboard by a glued roll, and after the back liner paper 3 is applied to the wavefront to form a double-sided cardboard, The double-sided cardboard is slidably moved on the upper plate portion 11 of the hot platen body 10 by the transfer force of the belt conveyor 5.

  At this time, in the hot platen device S, the heat receiving surface is heated from the upper plate portion 11 by the heat of the steam A supplied from the steam supply portion 16 to the space portion, and the heat is transferred to the heat radiating surface. The Accordingly, the double-sided cardboard that is slidably moved on the heat radiation surface by the transfer force of the belt conveyor 5 is heated by the heat through the back liner paper 3, and the adhesive paste is gelled by the heating at that time. Thus, the corrugated paper 2 and the back liner paper 3 are bonded and integrated.

  At that time, the heat receiving surface is formed in a wave shape, the area thereof is formed larger than the heat radiating surface, and the fact that the copper plating layer 14 is provided on the surface, the heat receiving surface is A sufficient amount of heat is efficiently received from the steam A so that the heat radiating surface can transfer heat to the alligator, and the amount of heat deprived by the back liner paper 3 can be supplied efficiently. Accordingly, it is possible to increase the operating speed, that is, the transfer speed of the double-sided cardboard, and the production efficiency can be improved. In addition, the number of hot platen devices S can be reduced with the addition of a simple configuration, and the size and cost of the equipment can be reduced.
