Patent ID: 7520934

Claim:
A gravure coating apparatus, comprising: a gravure roll that is rotationally driven at a peripheral velocity; a manifold block that continuously coats a coating solution on an outer peripheral surface of the gravure roll by immersing a lower part of the outer peripheral surface in the coating solution; a doctor blade that scrapes off a redundant part of the coating solution coated on the outer peripheral surface from an upper part of the outer peripheral surface of the gravure roll rotationally displaced upward having the coating solution coated thereon; and a dam block extending from the manifold block on a side where the outer peripheral surface of the gravure roll moves out from the manifold block by rotation of the gravure roll, wherein a tip end of the dam block is disposed above an axial center of the gravure roll and below a scraping point where the redundant part of the coating solution on the outer peripheral surface of the gravure roll is scraped off with the doctor blade, wherein a difference between the tip end and the scraping point is from 3 to 25 mm in a vertical direction, and wherein the gravure roll has a diameter of from 20 to 300 mm.
