Abstract
In the coating method of a viscous material according to the present invention, a nozzle body having outlets corresponding to many coating rows is employed. The nozzle body is moved, while the gap between the nozzle body and the surface to be coated is maintained constant, so that the viscous material composed of different kinds of materials is discharged out of each outlet, thereby to effect simultaneous coating of the viscous material composed of different kinds of materials in many rows. Therefore, the present invention has such advantages that the surface to be coated is less stained, and at the same time, the surface to be coated becomes more smooth.
