In operation clamps 18, 19 are lowered on to the sheet and blocks 15, 16, with their respective clamps, a spaced away from the counterpunch 13. A corrugation 24 is formed by the punch press while at the same time blocks 15, 16 move towards the counterpunch 13. After the formation of the corrugation 24, the punch 14 and clamps 18, 19 are raised and the counterpunch 13 ejects the formed corrugation and at the same time lifts any previously formed corrugations from troughs 17. The sheet is then fed forward by a distance equal to the pitch of the corrugations and the clamp 19 lowered to clamp the formed corrugations in the troughs 17. The clamp 19 and block 16 are moved away from the punch press so as to shift the sheet forward by a distance equal to the side wall depth of a corrugation. The raised clamp 18 and block 15 are also moved away from the punch press. Finally the clamp 18 is lowered and the corrugating operation repeated.
