Abstract

In the rolling of tubes from cylindrical and preferably heated metal blanks by piercing the blank with a mandrel and then rolling it between inclined rolls, the blank is fed to the rolls through at least one bushing (4) having a diameter only slightly greater than that of the block and mounted in a housing (1, 2, 3) by means of axially-spaced ball-bearings (5, 6) for free or driven rotation. Since the blank is rotated by the inclined rolls, the use of a rotatable bushing (4) avoids the production of surface faults by friction with the inner wall of the inlet channel. Preferably a plurality of bushings spaced apart in series is used to support the full length of the blank. <IMAGE>
