Abstract
A method of forming a reinforced rubber sheet useful for the lining of pipes, acid tanks, chimneys and the like, wherein a metal grid is interposed between adhesive surfaces of each of two rubber sheets, the rubber sheets overlapping the metal grid along all edges, evacuating the air from between the sheets to thereby draw them together and also to draw them into contact with the metal grid, thereby effecting adhesion between the adhesive surfaces of the two sheets of rubber and also between the rubber sheets and the metal grid.
Claims10
A method of forming a reinforced elastomeric polymer comprising forming a reinforcing metal grid to have longitudinally extending members and joining members joining the longitudinally extending members, the surfaces of the joining members being displaced from the common tangential planes of the surfaces of adjacent said longitudinally extending members,
- rendering one face of each of two sheets of elastomeric material adhesive, the length and width of each of said sheets exceeding respectively the length and width of the reinforcing grid,
- interposing the reinforcing grid between said two sheets with the adhesive surfaces of the sheets contiguous and lying in planes displaced from said common tangential planes, and with the edges overlapping the edges of the metal grid on all sides, thereby forming air flow channels between and defined by the longitudinal members and said adhesive surfaces,
- evacuating air through said air flow channels and from between the sheets to thereby draw said adhesive surfaces together around the periphery of the metal grid and in the areas existing between the longitudinally extending members and joining members, and
- effecting adhesion between said adhesive surfaces.
