Double-sided coating device

A double-sided coating device, comprising:

• a conveying mechanism that continuously conveys a base material of elongated shape, the base material including a first surface and a second surface located opposite to the first surface;
• a first die that applies a first coating material onto the first surface;
• and
• a second die positioned on the downstream side of the first die in a conveyance direction of the base material to apply a second coating material onto the second surface,
• the conveying mechanism comprising:
• a roll that is positioned on an upstream side of the second die in the conveyance direction, that conveys the base material while supporting it at the second surface on a circumferential surface of the roll, and that sends out the base material to the downstream side in the conveyance direction such that the first surface coated with the first coating material faces upward whereas the second surface to which the second coating material has not been applied faces downward, a position at which the base material separates from the circumferential surface being higher than a target coating height of the base material at which the second surface is spaced away from the second die by a predetermined amount;
• and
• a drawing section that is positioned between the roll and the second die in the conveyance direction and that draws the base material such as to bring it closer to the target coating height wherein the drawing section comprises a suction part facing the second surface to suck the second surface, and the conveying mechanism comprises a pair of flow regulating members arranged on the both sides of the base material with respect to a width direction of the base material to regulate entry of atmosphere between the suction part and the second surface at an end of the base material.
