PURPOSE: To make effective use of the laminating time by providing a floater in an elevatable manner, and providing an elevating means to elevate the floater to enable the advancement of the laminated iron sheets on a carrying shuttle without being interrupted by the presence of the floater.

CONSTITUTION: A lifter 11 is in the carriage stop position of a carrying shuttle 1, and supporting bodies 12 arranged in a notch groove part 5 formed in a loading table 4 of the carrying shuttle 1 is in the elevatable condition. The carrying shuttle 1 is advanced between the supporting bodies 12 without the supporting bodies 12 being interrupted, and when the supporting bodies 12 support laminated iron sheets 33, the carrying shuttle 1 is released from the support, and retracted to the original position, and can execute the loading work of the laminated iron sheets to be carried next. When the carrying shuttle 1 is advanced, a frame body 25 is elevated along a guide rail 23, and a separator 26 is also elevated, and the frame body can pass without the separator 26 being interrupted even when the amount of the laminated iron sheets 33 is increased.
