Abstract
A roll press device is provided and includes a pair of press rolls; and an auxiliary roll that is disposed on at least one of upstream and downstream of the pair of press rolls, wherein the roll press device is configured to press a laminate structure by allowing the laminate structure to pass between the pair of press rolls, and wherein a laminate structure contact surface of the auxiliary roll is positioned above or below a virtual plane that the laminate structure includes when the laminate structure passes between the pair of press rolls.
Claims10
A roll press device comprising:
- a pair of press rolls;
- and
- an auxiliary roll that is disposed on at least one of upstream and downstream of the pair of press rolls,
- wherein the roll press device is configured to press a laminate structure by allowing the laminate structure to pass between the pair of press rolls, and
- wherein a laminate structure contact surface of the auxiliary roll is positioned above or below a virtual plane that the laminate structure includes when the laminate structure passes between the pair of press rolls.
A method for producing a laminate structure comprising:
- pressing the laminate structure while passing between a pair of press rolls,
- wherein the laminate structure includes:
- a substrate including a first surface and a second surface opposite to the first surface;
- a first layer provided on the first surface of the substrate;
- and
- a second layer provided on the second surface of the substrate,
- wherein
- the first layer includes a first end portion and a second end portion along a width direction of the substrate,
- the second layer includes a third end portion and a fourth end portion along the width direction of the substrate,
- the first end portion is opposite to the third end portion,
- the second end portion is opposite to the fourth end portion,
- the third end portion is positioned closer to a central portion side of the substrate than the first end portion, and
- an end surface of the third end portion includes an inclined surface or a stair shape or a combined shape of the inclined surface and the stair shape.
A method for producing a laminate structure comprising:
- using a roll press device,
- wherein the roll press device includes
- a pair of press rolls, and
- an auxiliary roll that is disposed on at least one of upstream and downstream of the pair of press rolls,
- wherein a laminate structure contact surface of the auxiliary roll is positioned above or below a virtual plane that the laminate structure includes when the laminate structure passes between the pair of press rolls, and wherein the laminate structure is pressed wile passing between the pair of press rolls, and
- wherein the laminate structure includes:
- a substrate including a first surface and a second surface opposite to the first surface;
- a first layer provided on the first surface of the substrate;
- and
- a second layer provided on the second surface of the substrate,
- wherein
- the first layer includes a first end portion and a second end portion along a width direction of the substrate,
- the second layer includes a third end portion and a fourth end portion along the width direction of the substrate,
- the first end portion is opposite to the third end portion,
- the second end portion is opposite to the fourth end portion,
- the third end portion is positioned closer to a central portion side of the substrate than the first end portion, and
- an end surface of the third end portion includes an inclined surface or a stair shape or a combined shape of the inclined surface and the stair shape.
