Abstract

PURPOSE: To impregnate a substrate with resin liquid quickly and sufficiently by a method wherein the resin liquid is penetrated from the back side of the substrate into the substrate while hot air is being blown on the surface of the substrate in the direction approx. parallel to the surface thereof.
CONSTITUTION: The backside of the substrate 1 like paper etc. being fed continuously by rollers 9 is impregnated with resin liquid 2 like phenol resin, varnish, melamine resin and urea resin varnish, etc. When hot air is blown from the blast port of a blast duct 4 provided near the surface side, in the direction approx. parallel to the substrate, atmospheric pressure difference due to the blast occurs at the space between the surface side and the backside of the substrate. The atmospheric pressure becomes slightly smaller on the surface side than on the backside, while the resin liquid immerses into the substrate in a shorter time and is impregnated sufficiently within the desired time.
