ある。Structures of conventional examples 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 in which oil is applied using an oil transfer roller; and (5) a method in which, after vapor deposition, the vapor-deposited metal is mechanically treated with an electrode to remove only the insulating margin portion.

。2. Metallized films produced by these methods are shown in Figures 1 and 2.
As shown in the figure, especially in Figure 2, the metallization of wound type and multilayer capacitors is provided with a safety mechanism in the event of dielectric breakdown by dividing the metal vapor deposited part to prevent smoke and ignition. It's a film. In addition, Figure 1,
In FIG. 2, 1 is a film to be deposited, 2 is a deposited metal film, 3 is an insulation margin part, and 4 is a divided insulation margin part.

測できる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 not possible during production. A method that could be used 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 a safety mechanism as shown in FIG. It was hoped that it would be possible to conduct observation checks during manufacturing.

数形成されたものを観測検査する場合、便利である。Since this stroboscope lamp 6 is a light source that repeatedly emits instantaneous light, when illuminating the film surface during the production of metallized film, if the cycle of repeated light emission is equal to the speed cycle of the metallized film, or the third If the speed period is equal to the speed period of the divided insulation margin parts 4 shown in the figure, observation and checking can be performed with the divided insulation margin parts 4 in a stationary state, as shown by the broken lines. The emission 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, like the 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.

に大きな向上を得ることができる。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, especially unclear margins, partial absence of margins, etc. The margin shape, etc. can be clearly confirmed visually, and if there is a quality abnormality as mentioned above, immediate action can be taken, which improves the quality of metal films.
You can get a big improvement in productivity improvement page 5.
