Abstract

1341730 Making apertured panels; stamping D J MOUNTENEY 2 June 1972 [12 March 1971] 6748/71 Headings B3A and B3Q [Also in Division B5] To produce a perforated metal panel, e.g. of a cold forming metal alloy, a sheet of the metal is formed between male and female press tools to a shape having a plurality of projections of cross-sectional area corresponding to that desired for the apertures; the sheet is then cut across the projections by a tool moving across the sheet and parallel to it.
