Abstract
Procedimiento para la obtención de hojas con efectos ópticos. La hoja es trabajada para visualizar en ella los correspondientes motivos, estando constituida dicha hoja por una resina transparente en la que se realiza la grabación de los motivos que producirá los efectos ópticos. Es característico que la resina caliente, en estado fluido o formando película, sea suministrada a una calandria metálica refrigerada compuesta de un cilindro y de una placa matriz envolvente grabada con los motivos a transmitir a la. resina que es polimerizada por el frío de la calandria, coincidiendo el suministro de la resina a la calandria junto al punto donde actúa un rodillo presionador aplicado contra la calandria y también refrigerado. La resina que se graba y polimeriza sale de la calandria guiada por un rodillo aplicado contra ella y también refrigerado.Procedure for obtaining sheets with optical effects. The sheet is worked to visualize in it the corresponding motifs, said sheet being constituted by a transparent resin in which the recording of the motifs that will produce the optical effects is made. It is characteristic that the hot resin, in a fluid or film-forming state, is supplied to a refrigerated metal calender composed of a cylinder and an embossed matrix plate engraved with the motifs to be transmitted to it. resin that is polymerized by the cold of the calender, coinciding the supply of the resin to the calender next to the point where a pressing roller applied against the calender and also cooled. The resin that is etched and polymerized leaves the calender guided by a roller applied against it and also cooled.
