Abstract

220,497. Singer, F., and Fenag Tubenfabrik Ges. Feb, 20, 1923. Drawings to Specification. Collapsable tubes.-Thin walled tubes of aluminimum are made bv the cold extrusion in one stage of square instead of the usual circular blanks. These blanks may have a central hole and they are made by cutting without waste from strips of metal of the width and thickness of the blanks. The strips are obtained by cutting, roll ing or extrusion.
