Angle-profile rolling method and apparatus

In a method of making angle profiles using a rolling apparatus having

• an upper and a lower horizontal profile roll rotatable about respective parallel upper and lower axes and together defining an open or closed roll gap that lies in a rolling plane perpendicular to a travel direction of the rolling stock;
• and
• at least one pair of nonhorizontal edging rolls that laterally compress the rolling stock and define a rolling plane extending perpendicular to the travel direction of the rolling stock, the rolling plane defined by the profile rolls and the rolling plane defined by the pair of edging rolls are not coplanar with each other,
• the step of, prior to or after passing the rolling stock through the horizontal profile rolls, deforming the rolling stock by at least one pair of nonhorizontal edging rolls.
