Abstract: Presented is a method of manufacturing opened at both ends thin walled elastomeric sleeves of complex shapes. The proposed technique employs standard dip molding process but with modifications which enable producing of opened at both ends sleeves right from the drying stage and eliminates the necessity of cutting lower dipped ends subsequently to the dipping process. This technique allows sleeves to be manufactured with rolled beads at both ends. The main benefit of the present invention is a possibility of manufacturing sleeves on existing standard automated and semi-automated dip molding lines, traditionally used for manufacturing elastomeric gloves and condoms. The gist of the invention is a composition of a dipping former with a bottom coated by hydrophobic material such as PTFE. This composition impedes buildup of coagulant and coagulum on the bottom. The loose coagulum layer is removed by means of washing off with directed and appropriately timed sprinklers.

Abstract: An apparatus and method for manufacturing elastomer surgical gloves or the like is disclosed. Ordinarily, a glove mold having a handshaped mold member with spaced fingers is dipped into a tank containing a liquid polymer. As the glove mold is slowly withdrawn, polymer latex webs tend to form between the fingers of the mold. In order to prevent the formation of these webs, small objects such as polyethylene balls are moved fairly rapidly along the surface of the polymer. These small objects pass through the spaces between the fingers to prevent the webs from forming.

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.
