Abstract
A laundry machine drum has a sheet material skin including an arrangement of a plurality of perforations therethrough. Each of one or more of the perforations includes a shear cut in the sheet material. The sheet is deformed in the region of the shear cut such that the edge of the sheet material of one side of the shear cut is offset from the edge of the sheet material of the other side of the shear cut over at least some of the length of the shear cut. An opening is formed between the offset edges. The apparent area of the opening is greater when viewed from at least one direction substantially parallel to the general plane of the drum skin in the region of the perforation than when viewed from a direction substantially perpendicular to the general plane of the drum skin in the region of the perforation.
