as a billet b is fed between the scalping die 6 and pressing stem 12 by a billet loader which is not shown a fluid pressure oil pressure is applied to the pressurized mechanism 8 in an expanding direction to press the billet b against the die 6 by the pressing stem 12 scalping the skin of the billet b along the entire length thereof as shown in fig1 and 5 the chips which are curled into a spiral form under the guidance of the end face 6a of the die 6 sometimes tend to deposit on the end face 6a as shown in fig5 therefore after retracting the pressurizing stem 12 as shown in fig2 the drive units 19 are extended in the present embodiment as indicated in phantom in fig5 moving the chip ejector 18 axially beyond the end face 6a of the scalping die 6 as a result the chips 17 are removed from the end face 6a and discharged out of the machine through the chute 22 as shown in fig3 in the meantime the chip ejector 18 is retracted to its original position by a contracting operation of the drive units 19 until the chip ejection in the next cycle of operation fig6 illustrates a second embodiment of the present invention where those component parts which have correspondents in the first embodiment are designated by corresponding or like reference numerals as seen in fig6 a die holder 15 of u shape supports a.
