Abstract A method and apparatus provided for manufacturing elastomer gloves having percentage elongation of at least 300%. In order to prevent excess deposits of the polymer latex in the areas of the tips of the fingers and the webs between the fingers when the hand-shaped molds are coated, by dipping, with the polymer, the surfaces of the mold in these areas are formed as non-rounded, non-horizontal inclined surfaces which join at an apex and define an included angle therebetween. This arrangement prevents the pooling of the polymer latex in the areas in question, this pooling being the cause of the excess deposits and being characteristic of prior molds of this general type. In order to provide sufficient coagulant around the sharp corners formed in the areas of the tips of the fingers and the webs between the fingers so as to provide sufficient coating in those areas, it is necessary to use a heated mold and to provide sufficient dwell time and withdrawal time for the mold from the coating baths during the process.
A molding device for molding gloves having a percentage elongation of at least 300%, said device including a tank containing a polymer, a pair of glove molds supported on a suppot arrangement adapted to be submerged in said tank so as to provide a coating of said polymer on said molds, each of said glove molds comprising a handshaped mold member including separate, spaced fingers and the tips of the fingers and the spaces between the fingers comprising non-rounded, non-horizontal inclined surfaces which are joined at an apex and define an included angle therebetween.
