Abstract

1309465 Making expanded metalwork EXPANDED METAL CO Ltd 30 June 1970 31676/70 Headings B3A B3E and B3W An expanded metal sheet, Fig. 10, is made by advancing metal sheet 22, Fig. 1, stepwise beneath a serrated edge knife 23 which severs the sheet between successive steps, and thereafter stretching the sheet in the direction of advance until at least some of the strands 34, Fig. 10, are aligned longitudinally. The metal sheet 22 is advanced stepwise between a shear plate 20 and punch 21 having teeth 23 separated by depressions 24. The punch moves laterally after each shearing operation which also causes some expanding of strands 28 to produce an expanded sheet, Fig. 9 (not shown). The expanded sheet is then stretched by two pairs of rollers 38, 39 (Fig. 11, not shown) to form the structure of Fig. 10. In a modification the teeth of the punch are pointed as at (53, Fig. 12, not shown) which produce an expanded sheet, Fig. 17 (not shown) which is stretched to the shape shown in Fig. 18. Bending of the longitudinal edge of the stretched expanded metal produces a smooth edge (Fig. 19, not shown).
