FIELD: technological processes. ^ SUBSTANCE: multilayer protective element is produced with two protective features in certain position relative to each other, which are set on two separate film beds (100, 200). The latter are interconnected by duplication, at that, in ready material an accurate adjustment of protective features relative to each other is provided. To provide accurate adjustment of protective features, each film bed is equipped with adjustment marks. These are used to control relative position of the beds when interconnecting. The controlling implies stretching the bed, whose marks are late relative to marks on the other bed. ^ EFFECT: simple production of protective element is provided. ^ 16 cl, 9 dwg |
