摘要：
Method and apparatus for applying a continuous layer of glass frit to a connection or sealing edge surface of the funnel portion of a picture tube. The glass frit flows onto such surface from a nozzle of a glass frit containing pot while the funnel portion is carried by a turntable. Means are provided for rotating the turntable at such a speed that the relative speed, between the nozzle and the connection surface positioned therebelow, is substantially inversely proportional to the width of the connection surface.
