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 As the glove mold is slowly withdrawn, polymer latex webs tend to form between the fingers of the mold.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.
