In a skew-rolling stand for rolling hollow billets, in particular for stretching hollow billets into tubular blooms, work material guides are provided at the entry end and/or at the delivery end. These work material guides comprise a preferably motor-driven guide tube (19) which can be rotated about its longitudinal axis, which considerably improves guiding and offers additional protection against heat losses and scaling of the work material. The guide tube does away with the need for a re-heating furnace and allows immediate subsequent finish-rolling.
