PCT No. PCT/SE87/00424 Sec. 371 Date Mar. 14, 1989 Sec. 102(e) Date Mar. 14, 1989 PCT Filed Sep. 22, 1987 PCT Pub. No. WO88/02416 PCT Pub. Date Apr. 7, 1988.Soft paper from cellulose fibres is manufactured by wet-forming a first fibre layer. Thereafter air-borne dry fibres are deposited directly on one or both sides of the wet-formed layer while this is still wet, so that a second and possibly a third fibre layer are formed on the first one. Fibre bindings thereby arise between the layers. The wet-formed fibre layer gives the soft paper its strength, while the dry-formed fibers give a soft surface.
