Abstract

A method for manufacture of a pre-impregnated product including causing a substrate moving at a linear speed of at least 100 meters per minute to generally horizontally traverse a first coating stage at which impregnation particles are caused to be deposited onto a first surface thereof, thereafter causing the substrate moving at a linear speed of at least 100 meters per minute to generally horizontally traverse a first heated pressing stage at which the impregnation particles are caused to be impregnated into the substrate from the first surface, thereafter causing the substrate moving at a linear speed of at least 100 meters per minute to generally horizontally traverse a second coating stage at which impregnation particles are caused to be deposited onto a second surface thereof and thereafter causing the substrate moving at a linear speed of at least 100 meters per minute to generally horizontally traverse a second heated pressing stage at which the impregnation particles are caused to be impregnated into the substrate from the second surface.
