Abstract

PURPOSE: To form a good film of uniform thickness automatically, continuously and efficiently by providing binder tanks and sand tanks on the same circumference centering at a vertical shaft.
CONSTITUTION: A tree 4 is conveyed up to the dipping position, where a flange 5 is press-contacted with a rotary transmission plate 52. When a vertical shaft 7 revolves and the free 4 stops in the position above the 1st binder tank 12, an elevating cylinder 25 operates, and a piston rod 26 retreares, then the tree 4 is dipped into the tank 12, and a rotating arm 38 is rotated to rotate the tree 4 in an inclined state so that the binder sticks over the entire circumference of a pattern 4'. The tree is lifted upward by the ascending of the piston rod 26, and after draining of the liquid, the 2nd cylinder 20 operates to revolve the vertical shaft 7. When the tree 4 comes over the 1st sand tank 13, the piston rod 26 is lowered. In the state that the tree 4 is held dipped in the sand tank 13, the tree is rotated so that the sand sticks over the entire outside circumference. After sticking of the sand, the tree 4 is pulled upward, and the arm 28 is rotated ro reset the tree 4' to the vertical state.
