Abstract
594,419. Flanging angle-bars. BUDD MANUFACTURING CO., E. G. March 6, 1945, No. 5566. Convention date, March 9, 1944. [Classes 83 (ii) and 83 (iv)] Curved channel-section &c. bars are formed by clamping a curved sheet to a curved mandrel and feeding the sheet and mandrel through rollers which form the flanges. A curved sheet 29, Fig. 3, is positioned by registering pins not shown and clamped to a flat curved mandrel 31 through a pressure plate 32 by a presser 52 actuated by a fluid cylinder 124 and the mandrel is fed by electromotor driven recessed rollers 58, 59 which bend the flanges. The strip passes by interposed roller tables through three pairs of rollers which bend the flanges through 60 degrees, 90 degrees and finally set the flanges respectively. The rollers 59 are mounted in slides adjusted by screw means 74. The rollers 58 are mounted in slides actuated by a fluid cylinder 45 with interposed means for tilting the roller for flanging at angles other than 90 degrees. The bearing for the roller 58 carries a curved rack 94 geared to a straight rack 95. When a clutch is operated by hand, a cam 101 is rotated to actuate the rack 95 against the action of a fluid cylinder 98 to tilt the roller.
