  • Patent number: 3960644
    Abstract: A pipe lining apparatus for lining pipe in situ with a fiberglas reinforced plastic. The apparatus includes guide rollers for holding the apparatus centrally of the liner in the pipe as the apparatus is drawn through the pipe. Rotating sprays apply a resin and a resin hardening catalyst to the interior surface of the lining and a rubber tube following the spray heads forces the resin and catalyst into the fiberglas of the liner. Rotating rollers then apply pressure to the liner to force the liner into intimate contact with the pipe being lined. A finish coat of resin mixed with wax covered with the catalyst is then sprayed on the liner.
