摘要

Process for the manufacture of paper or woven bands impregnated with aminoplast resins for surface finishing, applicable without other coadjuvants, by pressure and heat, on sheet phenolic resin materials, fiber plates, or chips, plywood and others, characterized by subjecting the bands to a first stage of impregnation with a solution of a resin that exhibits a high fluidity when effecting pressure bonding, effecting an intermediate drying of said first impregnation, and proceeding to a second phase of impregnation of the band with a layer of resin that shows a lower fluidity when making the unión by pressure and that is of fast hardening.
