  • Manufacturing of resin-aggregate pipes
    Patent number: 4001370
    Abstract: Methods of centrifugally molding a resin pipe or molding a layered composite pipe utilizing a rotating inner member are disclosed. The rotating inner member rotates at a speed higher than the centrifugally rotating mold and is movable towards and away from the mold surface. Movement toward the mold compresses the molding material between the rotating inner member and the centrifugally rotating mold. Movement away from the mold permits any material adhering to the inner member to be cleaned from said inner member due to the centrifugal speed of said inner member.
