Abstract

804,574. Cupping. CARBODIES, Ltd. Oct. 19, 1956 [Jan. 21, 1956], No. 2104/56. Class 83 (4). A metal sheet 32 is cupped between dies 30 and 31, the peripheral side-walls, e.g. 35, of a recess 34 and a ridge 33 of the dies 30, 31, respectively, being parallel to the direction of press-operation and spaced apart by an amount slightly less than the thickness of the edges of the sheet 32a, which are gripped by the inverted U-form peripheral channel to hold the sheet stretched during the operation of the dies. The recess may be formed by bolting members 37 and 39 to the upper die or may be cast integrally as is the ridge.
