Prepreg is a long base material such as paper or glass cloth, and a resin liquid such as thermosetting synthetic resin resin varnish.
It is created by impregnating it with water and drying it. In this case, in order to improve the impregnation efficiency of the resin liquid 2 into the base material 1, as shown in FIG. Squeeze impregnated roll 6
In the meantime, the base material 1 is passed through to secondarily impregnate the base material 1 with the resin liquid 2. However, in the state where the primary contact impregnation has been performed, the air bubbles 7 contained in the base material 1 are expelled from the inside of the base material 1 to the surface of the base material 1 due to the resin liquid 2 impregnated into the base material 1. A large number of these adhere to the surface of the base material 1, and during secondary impregnation, they are released into the resin liquid 2 in the impregnation tank 3, and a large number of them float on the surface of the resin liquid 2, and are drawn to the moving base material 1. Even if the base material 1 is uniformly impregnated with the resin liquid 2 by secondary impregnation, these bubbles 7 remain attached to the resin-impregnated surface of the base material 1 and are transferred to the squeeze roll, and the bubbles 7 are transferred to the resin-impregnated base material again. They were pushed into the material 1 or moved to the drying process while remaining attached to the surface, preventing uniform resin impregnation into the base material 1.

The present invention is characterized in that the long base material 1 is continuously impregnated in an impregnation tank 3 equipped with a screw roll 4 containing a resin liquid 2 and a bubble removal device 5, and then moved through a squeeze roll 6. Since this is a method of impregnating the base material with resin, a large number of air bubbles 7 floating in the impregnation tank 3
The bubbles 7 are collected by the screw roll 4 and then removed from the impregnation tank 3 by the bubble removal device 5, so that the bubbles 7 do not adhere to the resin-impregnated base material 1 and the resin-impregnated base material 1 is evenly distributed. The present invention will be described below based on examples.

Figure a shows a simplified sectional view, and Figure 2 b shows a simplified plan view.
An impregnation device is formed by an impregnation tank 3 in which a bubble removal device 5 such as an overflow device, and a squeeze roll 6 are disposed. For example, a long piece of kraft paper is used as the base material 1, and the base material 1 is
The resin liquid 2 is impregnated into the base material 1, and as the resin liquid 2 is uniformly impregnated into the base material 1, the bubbles 7 built into the base material 1 and the bubbles 7 attached to the surface of the base material 1 are removed from the impregnation tank. The resin liquid 2 in 3 floats on the surface, but is immediately collected by a screw roll 4 and removed to the outside of the impregnating tank 3 by a bubble removal device 5. In step 6, the amount of impregnated resin is adjusted and moved. The resin-impregnated base material 1 with built-in air bubbles 7 or without air bubbles 7 attached is dried in a drying process to form a prepreg, which is laminated and molded to form a laminate, a printed wiring board, etc. This is used to obtain decorative boards, etc. or,
A plurality of screw rolls 4 and bubble evacuation devices 5 may be provided as required.
