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.
