Abstract
A device for positioning at least one masking strip in a machine for metallizing wide film, enabling a film to be obtained with metallized zones and non-metallized zones. This device has at least two rollers with smooth surfaces which drive the masking strips, and are positioned to bring the masking strips over the film during the metallization. At least one comb is mounted near the metallization site to position and guide the masking strips over the film. The invention applies to machines for metallizing plastic films used, for example, in the manufacture of chip-type capacitors.
Claims12
Device for positioning a plurality of individual closed loop masking strips in a machine for metallizing wide film with narrow width metallized zones and non-metallized zones, comprising at least two rollers with a smooth surface which drive the masking strips, these driving rollers being positioned so as to bring the masking strips over the film during metallization, and at least one fixed comb engaging said strips for positioning and guiding the masking strips over the film.
Device according to claim further comprising a pre-guide comb, placed before said one comb.
An apparatus for metallizing dielectric films comprising
- a first roller,
- a second roller,
- a plurality of bands mounted on and extending between said roller with one band next to another, and with predetermined spaces between the bands,
- a comb having teeth and notches between said teeth positioned to engage said bands between said rollers with the bands in the inter-tooth notches, and said notches being of the same width as the bands passing therein, and said teeth being as wide as predetermined spaces between said adjacent bands, whereby said bands are precisely positioned with respect to each other, as said rollers and bands move relative to one another, and
- a printing position adjacent to said bands and in printing contact with said bands, comprises a metallization site at which a dielectric film to be metallized moves adjacent to said bands, as a metal is condensed on said dielectric film in the spaces between said bands, and as bands and dielectric film move past said site, and wherein said comb is placed in a position before said site and after the roller which is before said site.
