Abstract
The invention relates to a mill for rolling pipes or other bodies such as flat blooms, bars, rods and the like. The rolling mill is formed by an outer load-bearing structure in which holders are accommodated so as to be extractable therefrom; in the holders there are mounted lever arms (18, 19, 20) that are pivotable transversely to the rolling axis along which the pipes or bodies to be rolled advance. The arms support the working rolls (48, 49, 50) at one end and, at the other end, are secured to the respective holder by means of a pin (22, 23, 24). In the rolling mill of the invention, there are advantageously means for rotating the olders about the rolling axis; this enables the rolls (48-50) to be brought back to the ideal working condition when their dimensions are reduced as a result of periodic machining to which they are subjected for maintenance and their working attitude can no longer be reestablished solely by the swinging movement of the lever arms (18-20) that support them.
