Abstract

PURPOSE: To form film of uniform thickness and collect spattering liquid material by rotating a panel with its mormal as the central axis injecting liquid material into the internal surface of the panel and by inclining this axis continuously to the perpendicular.
CONSTITUTION: A cathode ray tube panel 21 is supported through a chuck 22 by a rotary part 23 which rotates with a normal Z' of the panel as the first central axis and the rotary part 23 is allowed to rotate at the required number of rotation through a rotary mechanism 24. On the normal Z' of the rotary mechanism 24, the second central axis 25 is installed forizontally or in the direction vertical to the paper surface as that it can change angles against the perpendicular Z continuously or intermittently. On the other hand a collector of the liquid material is equipped on a circular supporter 27 having a radius of R from the second central axis 25 so that it can move easily in the direction of an arrow 28. Therefore film can be formed uniformly and evenly on the whole internal surface of the panel and the spattered surplus liquid material can be collected.
