GRAVURE KISS COATER

摘要

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.

主权项

1. 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, anda 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.
