RESIN IMPREGNATING METHOD FOR BASE

摘要

PURPOSE:To impregnate a base with resin sufficiently in a short time by force infiltrating resin varnish into the base. CONSTITUTION:A base 3 is wound on a plurality of dip rolls 5 disposed in a resin impregnation tank 2 and the base 3 is fed out. Then the base 3 is immersed in resin varnish 1 in the resin impregnation tank 2 and the resin varnish 1 is infiltrated into the base 3. At that time, the resin varnish 1 is sucked from suction holes 6 of a plurality of dip rolls 5 into the dip rolls 5 and the base 3 is impregnated with the resin forcibly.
