The pusher 5 pushes down the rollers 10a-10d rotating in contact with the base 5 thereof by as much as a step C as the pusher operates. The roller rows 8a-8f are therefore risen upward from the datum plane of the rollers 3 of the charging table by means of connecting rods 13a, 13b and stands 14a, 14b. The billet 4 on the rollers 3 is transferred onto the roller rows 8a-8f when the rollers 8a-8f rise. the billet 4 is thus smoothly slid on the roller rows 8a-8f by the rotation of the rollers 9 on advancing of the pusher 5. The billet is then moved onto the roller rows 6 of a transfer part B.
