Description

  The present invention relates to a metal foil structure, and more particularly to a metal foil structure made of a metal foil molded body such as a range panel.

  Conventional metal foil molded bodies made of aluminum foil have been difficult to adapt to gas ranges and range hoods of different sizes depending on the model.

Therefore, an edge winding engagement structure as shown in Patent Document 1 and a manufacturing method thereof have been proposed.
The above-mentioned metal foil molded body uses two metal foils made of aluminum in order to bring out size compatibility and to cover more areas that are easily contaminated, and they are combined and their positional relationship is changed. As the metal foil structure, an edge winding engagement structure formed by overlapping edges of the metal foil and performing edge winding processing is used. This makes the metal foils slidable with each other, and the shape of the metal foil molded body can be easily changed.
