Abstract

A star-shaped array of channeled rolls in a rolling mill for rolling bar stock has the rolls pressed together with a pressing force exceeding the rolling force by a prestressing force sufficient to cause frustoconical flanks of the rolls to forceably press against one another. This stabilizes the rolls and also permits a fine adjustment of the diameter of the passage defined between them.
