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.

On fabrique ces dispositifs prophylactiques dans une atmosphère inerte par refroidissement de mandrins (178) sur lesquels les dispositifs doivent être placés, par trempage de ces mandrins dans une substance polymère dans un solvant/véhicule et un agent de démoulage, par rotation des mandrins pendant le trempage et après celui-ci et par évaporation du solvant après le trempage. L'appareil comporte un sas (6) entre une section où sont exécutées les opérations susmentionnées (section 4) et une section se trouvant au contact de l'air atmosphérique où l'on enlève les dispositifs des mandrins (section 2), opération qui est suivie du nettoyage des mandrins en vue d'une utilisation ultérieure.
