Abstract

L'invention concerne un moule pour le coulage de lentilles comprenant une bande de matériau présentant une série de parties embouties dont le diamètre, la profondeur et les contours correspondent à ceux des lentilles à couler, cette bande étant adaptée à un procédé de coulage en continu et pouvant être jetee après usage. La bande peut servir de glantage pour le surfaçage des lentilles coulées.The invention relates to a mold for the casting of lenses comprising a strip of material having a series of stamped parts whose diameter, depth and contours correspond to those of the lenses to be cast, this strip being suitable for a continuous casting process. and can be discarded after use. The strip can be used as a gluing for the surfacing of cast lenses.
