Abstract
Frame manufacturing process, characterized by the fact that part of a metal sheet or strip, continuous, which is given a longitudinal, continuous, convenient angularity, and in sections of previously determined length is practiced one transverse bends, which determine the corners of the frame, all of which, except one, are obtained by bending, while the last one is achieved by cutting the strap in the appropriate length and juxtaposing this end resulting from the cut made with the edge of the strap. Initiation of the formation of the frame whose edges are welded together. (Machine-translation by Google Translate, not legally binding)
