Claims (14)

1. Fremgangsmåde til fremstilling af brillestel (1), hvor i det mindste en forreste kant (2) eller et par sidestykker (3) på brillestellet (1) dekoreres, omfattende følgende trin: - dekorering af en film (5), - indføring af filmen i en form (4) og sprøjtestøbning af den forreste kant (2) og/eller sidestykkerne (3) med filmen påført disse, hvorved fremgangsmåden omfatter, før trinnet med hensyn til sprøjtestøbning af den forreste kant (2) og/eller sidestykkerne (3), et trin med hensyn til termoformning og trimning af filmen (5) til dannelse og formning af filmen i overensstemmelse med et profil, der svarer til en væg (7) i formen, på en sådan måde, at filmen (5) indført i formen formes og tildannes som en overflade på den forreste kant (2) og/eller sidestykkerne (3), der skal formes, hvorved termoformningen foretages ved at placere filmen (5) på et første kontaktelement (61), som er formet således, at det matcher formens (4) væg (7) og er lidt større med hensyn til dimension, og hvorved filmens trimning foretages ved at placere den tidligere ter-moformede film (5) på et andet kontaktelement (62), som er formet til at matche formens (4) væg (7) og har samme størrelse.
2. Fremgangsmåde ifølge krav 1, hvorved trinnet med hensyn til termoformning og trimning af filmen (5) foretages før trinnet med hensyn til indføring af filmen (5) i formen (4) og efter dekoreringstrinnet.
3. Fremgangsmåde ifølge krav 1 eller 2, og som omfatter et trin med hensyn til at sprøjtestøbe et første lag af den forreste kant (2) og/eller af sidstykkerne (3) uden filmen (5), hvorved den dekorerede, termoformede og trimmede film (5) indføres i formen (4) og placeres på det tidligere formede første lag af den forreste kant (2) og/eller sidestykkerne (3), idet formens (4) væg (7) således afgrænses af den forreste kants (2) og/eller sidestykkernes (3) første lag, således at efter støbningen er filmen anbragt imellem den forreste kants (2) og/eller sidestykkernes (3) to forskellige lag.
4. Fremgangsmåde ifølge ethvert af de foregående krav, hvorved termoform-ningstrinnet omfatter følgende trin: - forberedelse af et kontaktelement (6), som er tildannet til at matche formens (4) væg (7), - placering af et stykke af filmen (5) på kontaktelementet (6) med henblik på at forme det og tilpasse filmstykket (5) ved trimning af filmstykkets (5) dele, som rager uden for kontaktelementets (6) kanter.
5. Fremgangsmåde ifølge krav 4, og som omfatter, under trinnet med hensyn til formning af stykket af film (5), som er placeret på kontaktelementet (6), et trin med hensyn til opvarmning af filmdelen (5a), som er i kontakt med kontaktelementet (6), ved bestråling af filmdelen (5a).
6. Fremgangsmåde ifølge ethvert af de foregående krav, hvorved filmen (5) er fremstillet i en anden farve end den farve, hvori brillestellets (1) forreste kant (2) og/eller sidestykker (3) er fremstillet.
7. Fremgangsmåde ifølge ethvert af de foregående krav, hvorved filmen (5) trimmes langs i det mindste en tredimensional trimningslinje, hvorved filmen (5) trimmes langs tre tredimensionale trimningslinjer, hvor en første og anden lukket trimningslinje er omgivet af en tredje lukket trimningslinje.
8. Fremgangsmåde ifølge ethvert af de foregående krav, hvorved trinnet med hensyn til dekorering af filmen (5) udføres ved en sublimationsbehandling.
9. Fremgangsmåde ifølge ethvert af de foregående krav, og som omfatter et trin med hensyn til at frigøre den formede og trimmede filmdel (5a) fra det andet kontaktelement (62) til formens (4) væg (7).
10. Fremgangsmåde ifølge ethvert af de foregående krav, hvorved der går en forudbestemt tidslængde imellem termoformningstrinnet og trimningstrinnet, således at der åbnes mulighed for krympning som følge af afkøling af filmens (5) termoformede materiale.
11. Apparat til fremstilling af brillestel (1), som har en forreste kant (2) og et par sidestykker (3), hvor den forreste kant (2) og/eller sidestykkerne (3) dekoreres, omfattende: - en station (CC) til dekorering af en film (5), - en form (4) til sprøjtestøbning af brillestellet (1), hvor formen (4) er sammensat af to dele (4a, 4b), som kan kobles til hinanden med henblik på at fremstille et formhulrum (C), som har en væg (7), hvorpå filmen (5), der skal anbringes på den forreste kant (2) eller sidestykkerne (3), placeres, hvilket apparat omfatter: - en filmformnings- og -trimningsstation (11) udstyret med midler (13) til ter-moformning af filmen (5) til formning af et stykke af filmen (5) i overensstemmelse med et profil, der svarer til formens (4) væg (7), - formningsmidler (6, 9), som er konfigureret til at give stykket af filmen (5) formen af en på den forreste kant (2) og/eller sidestykkerne (3) værende overflade, der skal formes, før injektionen i formen, - et første kontaktelement (61), som er tildannet til at matche formens (4) væg (7) og er lidt større med hensyn til størrelse, og som er konfigureret til at modtage og understøtte filmen (5) under termoformning, - et andet kontaktelement (62), som er tildannet til at matche formens (4) væg (7) og er af samme størrelse, og som er konfigureret til at modtage og understøtte den tidligere termoformede film (5) og virke i forbindelse med trimningsmidler (9) til trimning af filmen.
12. Apparat ifølge krav 11, hvorved formnings- og trimningsstationen (11) omfatter: - i det mindste et kontaktelement (6) til formning af stykket af film (5), idet kontaktelementet (6) er tildannet til at matche formens (4) væg (7), således at der i formen (4) kan placeres en formdel (5a) af filmstykket (5), - midler (9) til trimning af de dele af filmen, der rager ud over kontaktelementets (6) kanter for at give filmen en endelig form.
