Abstract
A gravure kiss coater 1 includes a paint feeder 30 placed along a small-diameter gravure roll 10 having an outside diameter D in a range of 45-150 mm. The paint feeder 30 includes a doctor blade 32, a case 31, and a coating feed path 34,35. A distal end 32a of the doctor blade 32 is directed in a direction opposite to a direction of rotation of the small-diameter gravure roll 10, and the small-diameter gravure roll 10 is capable of contacting the substrate S within a range of rotation angles equal to or less than 90° from the distal end 32a of the doctor blade 32.
Claims4
A gravure kiss coater comprising:
- a cylindrical small-diameter gravure roll having an outside diameter in a range of 45-150 mm, and having an outer circumferential surface including a coating portion;
- and
- a paint feeder extending along the small-diameter gravure roll and feeding paint to the coating portion, wherein
- while rotation of the small-diameter gravure roll is controlled, a sheet-like substrate is coated with paint by pressing the coating portion against the substrate traveling while being stretched linearly,
- the paint feeder includes
- a doctor blade extending along the small-diameter gravure roll and having a distal end contacting the coating portion moving toward a location at which the coating portion contacts the substrate,
- a case supporting the doctor blade and forming a storage space that stores paint, and
- a paint feed path through which paint is fed to the storage space,
- the distal end of the doctor blade is located so as to contact the coating portion from a direction opposite to a direction of rotation of the small-diameter gravure roll, and
- the small-diameter gravure roll is capable of contacting the substrate within a range of rotation angles equal to or less than 90° from the distal end of the doctor blade.
