Claims
- 1. A process of coating a metal strip with a high-viscosity coating material, which comprises:
- forcedly applying the coating material, having a viscosity of at least 500 cp, and being under a pressure of at least 0.2 kg/cm.sup.2, to the surface of a gravure roll rotating at a circumferential speed of at least 50 m/min;
- removing any excess of said coating material from said surface of said gravure roll;
- transferring said coating material remaining on said surface of said gravure roll to a coating roll through a transfer roll; and
- coating said metal strip, running at a speed of at least 50 m/min, with said coating material from said coating roll.
- 2. A process according to claim 1, in which said coating material is pumped to and pressure fed onto said surface of said gravure roll through a slit nozzle.
- 3. A process according to claim 1, in which said pressure of said coating material is 1-2 kg/cm.sup.2.
- 4. A process according to claim 1, in which at least one smoothing roll is provided at the surface of said coating roll and is rotated at a circumferential speed deviating no more than .+-.50% of that of said coating roll.
- 5. A process according to claim 1, in which the viscosity of said coating material is 1000 to 80,000 cp.
