Abstract

747,433. Rolling. BERGBAUSTAHL GES. Nov. 2, 1953, No. 30270/53. Class 83 (4). [Also in Group X] In a method of rolling trough-shaped profile sections 1 with correspondingly shaped inner and outer surfaces for fitting one within the other, sections 6, 8 of different thicknesses are rolled between the same pair of rolls 2, 3 adjusted to the required distances apart and having overlapping projections 4 and recesses 5 to maintain a closed pass. A projection 12 rolled at the base seats on the inside surface of an interfitted profile.
