  • Method of making foam pipe insulation including controlling rate of product draw-off according to foam temperature
    Patent number: 4076781
    Abstract: The method includes use of a stationary hollow mandrel supported at one end, a pair of forming shoes over which strips of material are respectively pulled longitudinally of the mandrel to provide a cylindrical inner liner surrounding the mandrel and a cylindrical outer jacket surrounding the inner liner in spaced relationship thereto, a conduit having an outlet end portion disposed within the outer jacket above the inner liner, supply means for supplying foamable hardenable exothermic reacting liquid material to an inlet end portion to the conduit, additional supply means for separately supplying a fast acting catalyst to the foamable material in the conduit, means for reciprocating the outlet end portion of the conduit transversely over the inner liner, conveyor-mold means confining the outer jacket as the foamable foams and cures, rotatable tire means for pulling the insulation formed by the outer jacket, the cured foam, and the inner liner off the mandrel longitudinally thereof, a traveling saw for cutting
    Type: Grant
    Filed: June 23, 1976
    Date of Patent: February 28, 1978
