ABSTRACT:
Rods which are worked, for example, in a rolling mill by cross-wedge rolling are introduced into the mill by means of a second rod which is shifted forward for the length of the rod portion being worked, the second rod being subsequently returned through a distance exceeding an elongation of the worked rod during the rolling of the latter. The invention can be utilized for repeated feeding of rod-shaped elements, where a gap is required between the worked and the following supplied piece.
