IPC: D04H1/70
Filed: 1958-09-24
Abstract: 845,826. Catamenial appliances. NESS, I.S. Sept. 24, 1958 [Sept. 25, 1957], No. 30564/58. Class 81 (2). A non-woven cover for a sanitary napkin is made more moisture permeable, over the upper face of the pad, by a series of regularly arranged holes, The fibres bordering the holes being substantially parallel with the perimeters of the holes. The holes are formed by passing a length of non-woven material around a perforated drum and directing jets of water through it, the the resultant perforations being so arranged as to produce a continuous run of holes in the central area 12 of the wrapper, leaving unperforated areas 14, 14 for folding over the edges of the pad. Owing to the fact that the fibres are forced sideways by the jets, thus forming regions of greater density and compression between the holes, the web has greater strength over the perforated area than in the unperforated area. As a result of this the continuation of the perforated area for the full length of the wrapper gives greater strength to the securing tab when in use. Specifications 816,673, 836,396 and 836,397 are referred to.
