Described is a method for manufacturing light weight roller in which a thin metal roller casing (2; 10), such as a thin electroformed sleeve, is centred by journals (11, 12) after which inside the roller casing (2; 10) a low density filling is applied. The low density filling may be a set plastic foam or gas under pressure. In a further embodiment a metal inner roller casing (31) is present which is concentric with an outer roller casing (30). The space (33) inside the inner casing (31) and the space (32) between the inner casing (31) and the outer casing (30) may be filled with a low density material. Also is described a roller thus obtained having a roller casing (10, 20, 30, 40) of electroformed nickel of a thicknes between 100 and 500 mu m. <IMAGE> |
