Abstract

431,835. Making tube blanks. ALFINA IMMOBILIEN-, FINANZIERUNGS-, & VERWALTUNGS AKT.-GES., Glarus, Switzerland. Jan. 2, 1935, No. 155. Convention date, Jan. 3, 1934. [Classes 83 (ii) and 83 (iv)] Rolling.-A previously pierced bloom 1 with a cylindrical cavity placed on a tapered mandrel 3 is forced through small grooved rolls, the trough diameter d of which does not exceed twice the diameter d1 of the pass. The bloom may be tapered at 6 to a diameter d1, not greater than the pass diameter. The pass may consist of three grooved coacting rolls, and a number of such passes may be angularly placed relative to each other, e.g. at 90‹ in case of pairs of rolls forming passes.
