  • it can be applied to a flat substrate surface with high adhesiveness while remaining almost flat, and a functional part such as thick film printing of an electric circuit can be easily formed thereon.
  • a covering member with excellent translucency for decorative products by using a transparent sheet.
  • it can be used even when both the sheet and the substrate are flat, so the object to be attached can be greatly expanded.

Abstract

L'invention concerne un dispositif de collage de feuille qui, même lorsqu'une feuille avec une surface de collage qui est sensiblement plate mais a localement des parties en saillie de hauteur donnée est collée sur une surface de substrat plat, produit une surface en feuille sensiblement plate après l'opération de collage. Le dispositif de collage est un dispositif pour coller, sous pression, une feuille mince sensiblement plate, avec une surface de collage qui a localement des parties en saillie d'une hauteur d'entre 5 à 30 % de l'épaisseur de celle-ci à une surface de substrat plate, par l'intermédiaire d'une couche d'adhésif, lequel dispositif de collage de feuille a une partie de pressurisation d'une dureté de surface de moins de 50 conformément au standard de JIS K6253, qui est recouverte d'une couche élastomère d'épaisseur égale de 100 à 500 fois la hauteur des parties en saillie.
