Abstract

702,751. Angular bending. CROWHURST, A. E. Feb. 22, 1952 [Dec. 7, 1950], No. 29941/50. Class 83 (4) In making ring frames for mirrors &c. a metal strip 1 with ends butt jointed is shaped by locating it in an apertured die 2 and expanding a sectional die 5 by a conical member 6. The strip is clamped with a projecting edge which is bent in a press to the position shown dotted in the Figure, by the inclined edge of an apertured plate located on pins P. The plate is then reversed and the flange is bent at right angles to the strip by a flat edge of the aperture.
