Process for manufacturing a piezoelectric component

A method of producing at least one non-metallized strip on metallized flexible plastic film rolls and a method of producing stacked or wound capacitors using such rolls. One feature of the process of producing at least one non-metallized strip is that the said non-metallized strip is produced by a laser beam applied to the lateral face of a roll at a non-zero angle of incidence .alpha..

Process to produce at least one non-metallized strip on metallized

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.

Device for positioning masking strips in a metallizing machine

A stacked or coiled type of metallized flexible dielectric film capacitor is made by the direct superimposition of at least two metallized films, laterally offset with respect to one another so as to form alternating even-order and odd-order layers, designed to be connected to one another by lateral electrical connections. One of the faces of the films is entirely metallized and the gap between two same-order layers is filled with an insulator material itself covered by the lateral electrical connections.
