PURPOSE: To quicken assembling process by arranging both magnets in a dual magnet assembly simultaneously on a pole piece through cam action at the forward end of a member. CONSTITUTION: A magnet 10 constitutes a block having a pair of flat side faces 17, 18 and first and second pairs of external angles 11, 12 and 13, 14 wherein the external angles 11-14 define lines 15, 16 intersecting or touching each other. In order to arrange the pair of magnets 10 correctly on a pole piece 20, a subbase 44 having four posts 46 is included and the remaining part of the unit is supported thereon. A base 49 is supported on the end of the post 46 while spaced apart from the subbase 44 and the magnet 10 is fixed to a magnet piece 20 in the base 49. Two brackets 48 support a magnet pusher 42 and provided with a unit 40, e.g. a cylinder. The pusher 42 is operated with compressed air being controlled through a valve 72 and an anvil 43 enters into an adjacent trench 30. A magnet stopper 52 projects into a channel 50 to be held in place. |
