METHOD OF MAKING PROTECTIVE ELEMENT WITH BILATERAL COAT

摘要

FIELD: process engineering.SUBSTANCE: invention relates to making of protective element having substrate with at least one opening covered on one side by translucent film. Said film is applied over solid translucent coat on the substrate top and bottom sides. Note here that coat forming material is applied in large amount in zone of said opening or said opening is filled with filler completely prior to coat application.EFFECT: ruled out fouling nearby opening edges, stability of protective element at flexure.7 cl, 4 dwg
