Rolling mill and method for manufacturing helically shaped metal strips

The invention relates to a rolling mill for rolling helically shaped metal strips. The arrangement comprises a frame (9) with three rolls(10a,10b,11), of which at least one roll is mounted adjustable, a second conveyor track (15) via which a metal strip is supplied and a first conveyor track (12) onto which a first trolley (13) may slide onto which the second conveyor track (15) is connected. During rolling, the first trolley (13) will slide over the first conveyor track (12), which means that the rolling process will not be influenced by sidewards acting forces. As soon as the metal strip approaches an end of the rolling mill, the adjustable roll may be released and the first trolley (13) may be moved back, after which the rolling process may be resumed.
