  • Patent number: 4501545
    Abstract: Articles such as balloons, beach balls, and other inflatable items are manufactured by dipping a number of suitably configured forms into a bath of molten latex, leaving the forms in the bath until a desired thickness of latex has been deposited on the forms, withdrawing the forms from the latex and permitting the latex to at least partially dry, and thereafter stripping the latex from the forms. In order to produce globular inflated articles, forms of a generally globular configuration have been used. Certain forms have utilized flutes or other deviations from an entirely globular configuration, but the outermost portions of prior forms used for the manufacture of globular articles are generally spherical. The greatest diametric dimension of the forms has limited the permissible form-to-form spacing. The invention employs a number of spoon-shaped forms each having a convex surface and a concave surface.
