  • Machine for depositing product on a plane and horizontal surface, especially machine for depositing frit on cathode tube cones
    Patent number: 4800837
    Abstract: To make a deposit of frit on a cone, the invention proposes to keep the cone fixed during the application with only the applicator moving. To ensure the evenness of the deposit, the cone is centered with respect to a reference axis, and it is brought to a stop against a reference horizontal plane. When the cone is centered, its standard dimension is automatically determined, and the computer that controls the movements of the applicator makes it follow a corresponding standard path.
