PURPOSE: To enable automation under bad environment by providing an arrangement and movement device for hanger, separation device for holding the hanger one by one and rotation device for descending the hanger while rotating the separation device and releasing the hanger with separation device to lay this on a mold.

CONSTITUTION: The hanger 10 is laid on the arrangement and movement device 52 under arranging condition and shifted forward. Separation device 66 attracts one of the hangers 10 at the most front line in the arrangement and movement device 52 with a magnet 68 and the hanger is held by hands 72 and waited until the mold 16 comes to the position of an automatic hanger laying device 40. When the new hanger 10 comes to the position of automatic hanger layer device 40, by rotating the separation device 66 holding the hanger, the hanger is descended downward by the rotation device. The separation device 66 releases the hanger at the position descending the hanger 10 and the hanger is laid on the mold 16. By this method, the automation under bad environment of high temp. and the others can be executed.
