Device for manufacturing panel with functional film

A method for fabricating a panel with a functional film affixed on a surface thereof through a bonding source by using an apparatus including

• a main pushing roller unit, of which a roller travelling direction is a first direction and a longitudinal direction is a second direction in a plane perpendicular to said first direction, being capable of pushing said functional film against said surface of said panel through said bonding source across said surface of said panel from a first end portion to a second end portion opposite to said first end portion both of which intersect said second direction and travelling along said roller travelling direction;
• and
• a first follow-up displacement roller unit, of which a longitudinal direction is in parallel with said second direction and which is positioned on the side of said first end portion behind said main pushing roller unit relative to said roller travelling direction, being capable of pushing said functional film against said surface of said panel through said bonding source in a range of a first distance from said first end portion towards said second end portion and travelling along said roller travelling direction,
• wherein said first distance is smaller than a length of a side of said panel, said side of said panel connecting said first end portion to said second end portion in parallel with said second direction, and
• said main pushing roller unit is capable of travelling along said roller travelling direction, followed by said first follow-up displacement pushing roller unit in response to each other;
• said method comprising:
• a first step of disposing said panel, said functional film with its affixing surface facing said surface of said panel, said main pushing roller unit and said first follow-up displacement pushing roller unit positioned on the side of said first end portion behind said main pushing roller unit relative to said roller traveling direction at their predetermined positions;
• and
• a second step of controlling travel of said main pushing roller unit and said first follow-up displacement pushing roller unit in said roller travelling direction so that said main pushing roller unit travels, followed by said first follow-up displacement pushing roller unit, and both said main pushing roller unit and said first follow-up displacement pushing roller unit push said function film against said surface of said panel through said bonding source, to affix said functional film on said surface of said panel with respective pressures of said main pushing roller unit and said first follow-up displacement pushing roller unit.

An apparatus for fabricating a panel with a functional film affixed on a surface thereof through a bonding source, comprising:

• a main pushing roller unit, of which a roller travelling direction is a first direction and a longitudinal direction is a second direction in a place perpendicular to said first direction, being capable of pushing said functional film against said surface of said panel through said bonding source across said surface of said panel from a first end portion to a second end portion opposite to said first end portion both of which intersect said second direction and travelling along said roller travelling direction,
• wherein said main pushing roller unit comprises
• a main elastic roller having a center hole therethrough;
• a shaft inserted into said center hole;
• a main pushing part supporting both end portions of said shaft extending off said center hole;
• and
• a pushing part connected to said main elastic roller holding part, propagating a pressure for said main pushing roller unit to said main elastic roller holding part, and
• a clearance is provided at least between an inner wall surface of said center hole of said elastic roller and an outer surface of said shaft.

A method for fabricating a panel with functional film, wherein said functional film is affixed on said surface of said panel through said bonding source by using an apparatus including:

• a main pushing roller unit, of which a roller travelling direction is a first direction and a longitudinal direction is a second direction in a plane perpendicular to said first direction, being capable of pushing said functional film against said surface of said panel through said bonding source across said surface of said panel from a first end portion to a second end portion opposite to said first end portion both of which intersect said second direction and travelling along said roller travelling direction, wherein said main pushing roller unit comprises:
• a main elastic roller having a center hole therethrough;
• a shaft inserted into said center hole;
• a main pushing part supporting both end portions of said shaft extending off said center hole;
• and
• a pushing part connected to said main elastic roller holding part, propagating a pressure for said main pushing roller unit to said main elastic roller holding part, and
• a clearance is provided at least between a wall surface of said center hole of said elastic roller on a side where said surface of said panel is pushed and an outer surface on said side where said surface of said panel is pushed of a portion of inserted part of said shaft in said center hole.
