本発明は積層板の製造工程中の紙基材への樹脂含浸装置
に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for impregnating paper substrates with resin during the manufacturing process of laminates.

効果が低下するとい、う問題があった。Generally, when applying resin (2) to a paper base film to impregnate it, the temperature of the paper base film is raised in advance (the viscosity of the resin (2) is lowered and the penetration is increased). However, in the conventional equipment of this type, as shown in Fig. 1, a coating machine (3
There was a problem in that there was a distance between the coating machine (3) and the heating tube (5), and therefore the temperature of the paper base material (fl) decreased before it reached the coating machine (3), reducing the penetration effect.
本発明は上記の点に鑑みて為されたものであって、その

は受はロール、 （１５）はドレン管である。The gist of the present invention is to have a coating machine (3) that coats a paper base material (1) with a resin (2), and a dryer (4) that dries the coated paper base material fi+. A heating humidifier (5) is disposed close to the coating machine (3) so as to heat and humidify the paper base material (]) immediately before coating the paper base material (2). This invention relates to a resin impregnation device.Hereinafter, the present invention will be explained in detail based on illustrated embodiments. (
4), the paper base material filt/'i feeding roll (
6) These should be sent in groups. Coating machine (
3) is formed by immersing the lower part of the penetrating hole (8) in a dip pan (7) filled with a liquid resin (2) such as phenol resin. The heating humidifier (6) is made of paper base [j+
When the steam passes through the chamber (9), it is heated and humidified, and the steam supply pipe (10
) and hot air supply pipe (II), ff mixing pipe (12
) are concatenated. The male steam and high-temperature air sent into the chisel bar (9) are blown onto the paper substrate 111 through the slit holes (13). (14)
The receiver is a roll, and (15) is a drain pipe.

送られる。The heating humidifier (5) configured in this way is a coating machine (3).
Therefore, the paper base material il+ can be heated and humidified immediately before being coated with the resin (2). After coating, it is sent from the squeeze roll 06) to the dryer (4).
加熱加湿機（６）では紙基材（１）の温度を１０〜４０

れるのが適当である。In the heating humidifier (6), the temperature of the paper base material (1) is 10 to 40.
The water rate at 0 to 40 degrees Celsius should be reduced by 1 to 5 degrees. The paper base material (1) is then sent to the coating machine (3) when its moisture content reaches 6 to 8%, which is the most permeable to the resin. Also, the temperature of the paper base material +I+ is the boiling point of methanol, which is 6
Since the temperature is 4°C, it is appropriate to send it to the coating machine (3) at 25 to 45°C.

抜加工性等の改善が図れるものである。−In the present invention, a heating humidifier is placed close to the paper substrate to heat and humidify the paper substrate immediately before applying the resin, as in the case of vaporization, so that the resin is applied before the heating temperature of the paper substrate falls. This improves the penetration effect of the resin, and since the paper base material is pre-humidified, the penetration of the resin is even smoother, and the characteristics of this laminated laminate are flame resistance, dimensional stability, and punching workability. Improvements such as these can be made. −
