ABSTRACT:
A rolling line for billets, bars, wire rod or the like, e.g. a roughing line has one or more rolling stands each having three or more driven rolls which are adjustable towards and away from the work material by a worm drive and a screw. The rolls are brought progressively closer together before each pass of the work material, whose cross section is thereby reduced with corresponding elongation. The direction of rotation of the rolls is reversed between each pass, unless two stands for rolling in opposite directions are provided in which case it is possible for the stands to be continuously driven but alternately operative. The work material is turned about its axis through half a roll pitch angle between each pass.
