PURPOSE:To avoid increase of loss due to generation of strain while handling iron core pieces by laminating them through the alternate movement of two units of conveyors each of which carries iron core pieces by attracting them at the lower part thereof so that the leg irons are arranged with the predetermined interval. CONSTITUTION:A flapper 65 is used for laminating iron core pieces which form transformer or reactor etc., permanent magnets are used at the lower surfaces of the conveyors 64 and 62 located in the upper and lower sides in view of alternately attracting iron core pieces, and the iron core pieces attracted to the lower side conveyor 62 are directly shifted to a laminating truck 25. The iron core pieces attracted by the upper conveyor 62 are dropped on the carrying truck 37 provided on the truck 25 using the conveyors 67 and 66 and laminated on the iron core pieces on the truck 25 arrived precedingly using the conveyor 42. The iron cores are laminated on the truck 25 while repeating such operations while controlling the interval of iron core pieces.
