摘要

New procedure for the manufacture of boxes for mechanical and manual molding based on hot-rolled profiles, characterized in that firstly the preparation of the profiles themselves is carried out by means of hot rolling, whereupon a split is verified in them. It gives rise to a bulge in the form of a half-round by the part opposite to where the split is practiced, thus achieving the endowing of the profile of a great rigidity.
