A pair of rolls (190a, 180a) for forming a pattern on sheet material (101a), the first roll (190a) comprising a first forming portion (192a) for forming at least part of a first pattern (103a) on a sheet material (101a) and a second forming portion (191a) for forming at least part of a second pattern (110a) on the sheet material (101a), the first forming portion (192a) comprising a first array of projections and the second forming portion (191a) comprising a second array of projections, the second roll (180a) comprising a third forming portion (182a) for forming at least part of said first pattern (103a) on the sheet material (101a) and a fourth forming portion (181a) for forming at least part of said second pattern (110a) on the sheet material (103a), the third forming portion (182a) comprising a third array of projections and the fourth forming portion (181a) comprising an array of rebates, the second forming portion (191a) and the fourth forming portion (181a) being co-operable to emboss a pattern corresponding to the respective array of projections and rebates on the sheet material (101a) and the first (192a) and third (182a) forming portions are co-operable to cold work harden the sheet material (101a) to form an array of projections and depressions with each projection on one side of the sheet material (101a) corresponding to a depression on the other side of the sheet material (101a).
