Abstract:  
This invention relates to a method of descaling, sizing, rounding up, straightening, and polishing solid or hollow metallic rounds by a continuous progressive and automatic operation. As round bars and tubes come from a hot mill, or other devices producing similar material, they are not true to size, are not rounds, carry scale, and are not straight. The best "rounds" (which term throughout the specification and claims will be used to designate both solid bars and tubes) are therefore, as initially produced, not suitable for certain purposes which require material that is clean, straight, polished, and approximates true roundness and accurate size.
