The invention relates to a rolling machine for working a metal container having a longitudinal seam, especially a sheet steel container, in which a cylindrical body is bent out of a flat metal plate and the adjacent edges of the cylindrical body can be welded to one another, after which a discoid underside and, optionally, a corresponding top side are welded to the cylindrical body (=intermediate product) in order to form a closed container or a container which is open at the top. The problem posed by this method is that the inner welded seam edge is often depicted as the cause of early rust formation which results in the contamination of the filling item. According to the invention, the rolling process is carried out in a continuous rolling machine (18) in which a body (12) is loaded into the one station (=loading position A) and a finished body (12) is simultaneously unloaded in the other station (=unloading position B). To this end, the top inner roller supportin g part (26) is centrally mounted. During the rolling process, the rolling devi ce is mounted on the exterior. The distinctive feature of the continuous rollin g machine (18) is in the, so to speak, "floating in an alternating manner" bearing of the top roller supporting part, i.e. it is equipped with an alternating locking deviceor fixing bearing which is placed centrally and on the exterior.
