Flat printing screens can be coated on one or both sides by the method and apparatus. A liquid is applied to a screen by one or two squeegees secured to carriages moved up and down on rubber sprocket belts driven by a motor. The speed of application can be adjusted according to the desired thickness of the coating and the viscosity of the liquid. The squeegees are mutually offset somewhat in height to reliably prevent the liquid from running out when the squeegees are not in motion. Application takes place regularly and reproducibly even in the case of a thick coating. The drive by means of rubber sprocket belts and a counterweight ensure vibration-free movement of the squeegees along the screen. |
