Abstract
477,592. Making profile sections. METAL TRIM, Ltd., and PENKALA, E. June 29, 1936, Nos. 6434/37 divided out of 477,581 ; and 2289 /37. [Class 83 (iv)] Angular bending.-Profile sections are made by passing sheet-metal strip 1 between rolls, e.g. 12, 13, shaped so as not to press on the strip at the edges or bends, but on areas such as a and a<2> away from such edges and bends or where there may be lateral or longitudinal stretching, so as to prevent waves being formed at the edges or thinning at the bends. As the strip passes from one pair of rolls to another, the pressure area at each pair overlaps the previous pressure area to eliminate any grooves made in the preceding pass. 12a shows the recesses in the top roll and 13a the recesses in the bottom roll. Rolls as described in Specification 477,590 may be used. Specifications 477,581, 477,589, and 477,591 also are referred to.
