ABSTRACT:
A method of rolling rod in which at least first and second strands are jointly rolled in a mill line having at least one final multistrand stand operating at a rolling speed which is variable as a result of predictable rolling events. Downstream of this stand the strands are separated and passed through single-strand mill stands and loops are provided upstream of the first single-strand mill stand in each line. Each loop has a loop length which can vary between a minimum and a maximum value. Before each of the rolling events occur at least one of the loop lengths is changed to an event optimizing value.
