Abstract
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..
Claims8
A process for the preparation of at least one non-metallized strip on the surface of a completely metallized flexible plastic film roll, comprising impinging a laser beam onto a lateral face of said roll at a non-zero angle of incidence relative to said lateral face of said roll to produce at least one non-metallized strip on the surface of said metallized flexible plastic film, said angle of incidence of the laser beam relative to the lateral face of said roll determining the width of the non-metallized strip.
