Title
(EN) EMBOSSING MEMBER FOR PRODUCING DIFFRACTIVE MICROSTRUCTURES
(FR) ÉLÉMENT DE GAUFRAGE POUR PRODUIRE DES MICROSTRUCTURES DIFFRINGENTES
Abstract
(EN)
An embossing member (10) used for producing diffractive microstructur&thetas;s (201) giving a visual effect comprises a stamping surface (15) having a microstructure, fastening portions (16a, 16b), and at least one doubly curved portion (11) that connects the stamping surface (15) to the fastening portions (16a, 16b). The stamping surface (15) remains stably in its place between the fastening portions (16a, 16b). The embossing member (10) can be mounted quickly on its base (20), for example with screws (32), without using glue, solder or weldin .
(FR)
La présente invention concerne un élément de gaufrage (10) utilisé pour produire des microstructures diffringentes (201) donnant un effet visuel et qui comprend une surface d'estampage (15) ayant une microstructure, des parties de fixation (16a, 16b), et au moins une partie doublement incurvée (11) qui joint la surface d'estampage (15) aux parties de fixation (16a, 16b). La surface d'estampage (15) reste stablement en place entre les parties de fixation (16a, 16b). L'élément de gaufrage (10) peut être monté rapidement sur sa base (20), par exemple avec des vis (32), sans utiliser de colle ni de soudure.
