層板（１１）を得るという方法である。In the method shown in Figure 1, first, a plurality of long thermosetting resin-impregnated substrates (1) obtained by passing a plurality of long substrates through an impregnating bath containing a thermosetting resin face are continuously The laminated base material (3) is sent to a pair of squeeze rolls (2), and is pressed while squeezing the excess impregnated resin to form a laminated base material (3).Then, the laminated base material (3) is sent to a pair of laminating rolls (4), and the A long metal foil (5) is laminated on one or both sides to form a metal foil-clad laminated base material (6), and then sent to a heating furnace (7). The heating furnace (7
) is provided with a plurality of guide rolls (8) along the direction of travel of the laminated base material (6) at the entrance, inside, and exit, and a pair of pull-out rolls next to the exit guide roll (8). (9), and the laminated base material (6) is pulled by the pull-out roll (9), heated and cured while moving on a plurality of guide rolls (8), and then cutter.

Furthermore, the double belt press (12) heats and presses the material to harden it, and then the cutter (10) cuts it to a desired length to obtain a laminate (1 piece).

に製造するという方法であるため、生産能率が高い。The method shown in Fig. 2 does not involve cutting the pre-cured metal foil-covered laminated base material (6), applying it to a batch press, and heating and pressurizing it, but using a double belt press (
Since the method is to continuously manufacture the laminate (11) by curing under heat and pressure in step 12), the production efficiency is high.

困難であるとの課題がある。Precuring means that the thermosetting resin is cured to such an extent that the thermosetting resin in the laminate (6) flows during subsequent heating and pressure curing, for example, using a double belt press (12). [Problem to be Solved by the Invention] However, the metal foil-clad laminated base material (6) is not cured between the laminating roll (4) and the draw-out roll (9) or the double belt press (12). If the tension is strong,
If longitudinal waves or vertical wrinkles occur on the surface of the laminated base material (6), and if the tension is weak, the metal foil (5) in the laminated base material (6)
Since transverse waves and transverse wrinkles are generated, which are thought to be caused by the difference in thermal expansion between the resin-impregnated base material (3) and the resin-impregnated base material (3), there is a problem in that it is difficult to prevent the waves and wrinkles.

安定して得られることを見い出し、本発明を完成するに
至った。As a result of intensive studies in view of the above situation, the inventors of the present invention discovered that, in a manufacturing method in which a metal foil-clad laminated base material is continuously heated, a plurality of rolls are placed on the top and/or bottom surface of the laminated base material. If the load applied from these rolls to the laminated base material is increased as the precuring progresses, and then heated and cured, a laminate without waves or wrinkles can be easily and stably obtained. The present invention was completed based on the discovery that the present invention can be achieved.

いで更に連続的に加熱して硬化させることを特徴とする
積層板の製造方法を提供するものである。That is, the present invention continuously heats a metal foil-covered laminated base material, which is made by laminating a plurality of elongated thermosetting resin-impregnated base materials and has metal foil laminated on one or both sides thereof. In a method for producing a laminate in which the laminate is precured and then cured by heating, a plurality of rolls are arranged on the upper surface and/or the lower surface of the laminate substrate, and the load applied from these rolls to the laminate substrate is The present invention provides a method for producing a laminate, which comprises precuring while increasing the temperature as the precuring progresses, and then continuously heating and curing.
本発明の方法では、ラミネートロール（４）と引き出し

荷重をかけられているため、縦波や縦シワの発生を防止
できる。In the method of the present invention, even if strong tension is applied to the metal foil-clad laminated base material (6) between the laminating roll (4) and the pull-out roll (9) or the double belt press (12), the laminated Since a load is applied to the base material (6) from the rolls on the upper surface and/or the lower surface as the precuring progresses, the generation of longitudinal waves and vertical wrinkles can be prevented.

重であることが望ましい。At this time, especially in the initial stage of heating, since the viscosity of the impregnated resin is low, applying too much load is likely to cause resin pooling, resulting in poor surface smoothness and resin outflow. It is desirable that the load be the minimum necessary to prevent the occurrence of vertical wrinkles.
次に本発明を実施例により具体的に説明する。 Next, the present invention will be specifically explained using examples.

After pre-curing while increasing the load as the curing progresses, the laminated base material (6) is hard to generate waves and wrinkles, and is kept free of waves and wrinkles by a tuple belt press ( 12) can be cured under heat and pressure,
Then cut to the desired length by force and tar (10),
A laminate (11) is used.

好ましい。The installation positions of these rolls (13) and (14) may be any position where the laminated base material (6) has not yet lost its flexibility and is in a deformable state after the start of heating, and there are no particular restrictions. However, it is preferable to select a position where curing has progressed to such an extent that resin pooling or resin outflow will not occur due to the load received from the roll.
