PURPOSE:To permit rolling of a green strip having uniform material quality and strength and good shape at transverse ends by rolling powder and rolled stock while rolling forces are simultaneously exerted to said powder and rolled stock from the thickness and transverse directions thereof. CONSTITUTION:Rolling rolls 6, 7 are rotated and vertical rolls 23, 29 are moved in the axial line direction of the rolling rolls 6, 7 by adjusting screws 27, 33 provided to journal boxes 22, 28 of the vertical rolls 23, 29 to adjust the gap of the vertical rolls 23, 29 to the gap which is the same as a desired strip width. The powder 10 is supplied from a hopper 11 to the gap between the rolling rolls 6 and 7 and while the transverse ends are restrained by the vertical rolls 23, 29, the powder 10 is rolled by the rolling rolls 6, 7. The transverse spread of the powder 10 is thereby prohibited and the transverse compressive force is exerted to the part on both end sides as well. The green strip which has the uniform material strength over the entire surface in the transverse direction and has the good shape of the transverse ends is thus obtd.
