欠点があった。[Prior Art 1] Conventionally, as a method for laminating a laminate, a plurality of sets of laminates are placed one on top of the other with metal plates interposed between upper and lower heating bodies, and heated and pressed by the upper and lower heating bodies. The heat supplied from the upper and lower heating bodies is conducted sequentially from the laminated body near the heating body, and it takes time to reach an intermediate position. In this way, there will be variations in quality between laminates that have been heated for a short time and laminates that have been heated gradually, and in particular, there are disadvantages such as variations in punchability, dimensional stability, and warping/twisting.

A plurality of sets (usually 10 to 14 sets) of laminates 3 are stacked on top of each other with metal plates 2 interposed between the upper and lower heating bodies 1, 1. A preheating heating plate 4 is inserted at an intermediate position between the plurality of sets of stacked bodies.

This is to reduce the temperature difference between the laminate located in the middle between the upper and lower heating plates and the laminate near the heating element, and the heat source can be stopped or reheated if necessary. , an example of its structure is shown in FIGS. 2 and 3. It is made up of two upper and lower heat-resistant insulating plates 5, 5 with a heating printed circuit sheathed wire 6 sandwiched between them, and has a socket 7 for connecting to an external power source. In addition to the electricity mentioned above, the heat source used for the preheating platen may be steam, hot oil, etc., but since an additional heating element will be inserted in addition to the upper and lower heating elements, the plate should be as thin as possible. This is desirable. In this respect, a heating body in which a printed circuit sheathed wire serving as a heat source is enclosed between heat-resistant insulating plates such as polyester or polyamide is preferred.
