Abstract

432,703. Squirting. SCHLOEMANN AKT.-GES., 13, Steinstrasse, D³sseldorf, Germany. March 20, 1935, No. 8685. Convention date, April 13, 1934. [Class 83 (iv)] A central hole is punched in a heated steel alloy or other billet B, the ends preferably being at the same time formed conical, the billet is then removed and turned on the outer surface concentrically with the punched hole, and is finally extruded into a tube. The piercing and forming of the ends of the billet may be effected in the extrusion press, or in another press.
