金属を除去する方法等がある。Conventional configurations and their problems In general, methods for forming insulation margins on vapor-deposited metallized films include (1) using a fixed mask, (2) using a tape mask such as a plastic film, and (3) spraying oil vapor. (4) a method of applying oil using an oil transfer roller; and (5) a method of removing the deposited metal only from the insulating margin by electrode or mechanical treatment after vapor deposition.

る。 Metallized films made by these methods are shown in Figures 1 and 2. In Figure 2, in particular, the metal vapor deposited portion is divided to provide a safety mechanism in the event of dielectric breakdown, thereby preventing smoke and ignition. This is a metallized film for wound and multilayer capacitors that prevents this from occurring. In FIGS. 1 and 2, 1 is a film to be deposited, 2 is a deposited metal film, 3 is an insulating margin part, and 4 is a divided insulating margin part.

方法が望まれていた。 Conventionally, when observing the surface of these metal-deposited parts and the insulation margin during manufacturing, the state of the metal-deposited film was visually observed by passing light from a fluorescent lamp, etc. When the feed speed of the metallized film exceeds 30 m/min, visual tracking becomes difficult and detailed observation is no longer possible during manufacturing. Therefore, it is now possible to observe the metallized film even at high speeds of about 30 to 300 m/min. A method was desired.

よう望まれていた。 In particular, in the case of metallized film capacitors, the quality of the metallized film greatly influences the electrical characteristics and life characteristics of the capacitor, so it is considered more important than ever. Furthermore, in the case of a metallized film equipped with the safety mechanism shown in FIG. 2, the shape of the insulating margin part 4 and the state of removal of the metal vapor deposited part are important points for the operation of the safety mechanism. It was hoped that observations could be checked during manufacturing.

る場合、便利である。 This stroboscope lamp 5 is a light source that repeats instantaneous light emission at a constant cycle, so it is used as a light source when illuminating the film surface during the production of metallized film.
If the emission period is equal to the moving time of one pitch (the length of one metal vapor deposited part 2 plus the length of one divided insulating margin part 4) of the metallized film moving at a constant speed, then
As shown by the broken lines in FIG. 3, the divided insulation margin parts 4 are observed and checked in a state where they are each stationary, that is, not in the conventional continuous moving state, but at fixed positions intermittently with good visibility. be able to. The light emitting period of this stroboscope can be freely varied according to the speed of the metallized film, so it can be used perpendicularly to the longitudinal direction, as in the case of a metallized film with a self-protecting capacitor shown in Figure 2. This is convenient when observing and inspecting a structure in which a large number of divided insulation margin parts 4 are formed.

産性向上に大きく貢献できる。Effects of the Invention As described above, according to the present invention, by installing a stroboscope, matters that could not be confirmed conventionally due to the fast winding speed of the metallized film,
In particular, blurred margins, partial absence of margins, margin shapes, etc. can be visually confirmed, and if any quality abnormalities such as those mentioned above occur, immediate action can be taken, which improves the quality of metallized films. It can greatly contribute to improving productivity.
