A diaper comprises a layer of cellulose pulp between layers of cellulose tissue, each of the tissue layers being either single or double; two further layers of cellulose tissue and non-woven material respectively being added under the lower tissue layer. The non-woven material extends on either side of the remaining layers and is folded round them to form an envelope, which is longitudinally sealed. The material inside the envelope may be sufficiently wide to enable one edge portion to be compressed, and/or furrows to be stamped in the longitudinal direction of the web which is folded along two longitudinal lines so that one edge portion overlaps the other and the compressed or furrowed portion will be in the centre of the material thus folded. Again, one or more plies may be included in the diaper material which enables the passage of moisture more easily in one direction than in the other. A web of treated paper fibre may replace the non-woven material. Diaper forming apparatus. Cellulose drawn from a reel 10, Fig. 1, in web form is fed to a disintegrator, after which the pulp is blown by fan through a pipe 12 and funnel 13 to fall on a web of cellulose tissue drawn from a reel 18. The web is carried through a suction box 19 by a perforated endless belt 14, and a second web of cellulose tissue 26 is applied by means of rollers 28, 29. The belt 14 is cleaned by a suction pipe 25 and brushes 22, 23. The web unit 30 so formed, Fig. 2, is carried through a second suction box 31 by an endless perforated belt 33 on to which is fed a further web 41 of cellulose tissue, a web 39 being supplied to form an envelope. A roller assembly 42, 43 turns up the edges of the web 39 around the narrower web unit 30 and web 41. Wheels 48, 49 keep the web edges stretched around guide plates 44, 45.
