Abstract
In the high speed production of elongated metal bars, a method of slitting a double or triple stranded bar interconnected at a continuous node or nodes, in which the bar is rolled to reduce the cross-section of each strand equally, the compressive working force being applied to create lateral tensile forces whereby the strands diverge and separate. In a triple stranded bar the two outer strands are worked in the same manner to separate them from the central strand.
