<p>Prophylactic devices are made in an inert atmosphere by cooling mandrels (178) on which the devices are to be deposited, dipping the mandrels into a polymeric material in a solvent/carrier and a mold release agent, rotating the mandrels during and after the dipping, and evaporating the solvent after dipping. The apparatus includes an air lock (6) between a section in which these functions are performed (Section 4) and a section located in an air atmosphere for removing the devices from the mandrels (Section 2), followed by cleaning the mandrels for use in a subsequent production run for making devices.</p> |
