PCT No. PCT/FR86/00208 Sec. 371 Date Feb. 24, 1987 Sec. 102(e) Date Feb. 24, 1987 PCT Filed Jun. 18, 1986 PCT Pub. No. WO87/00057 PCT Pub.

According to an additional characteristic of the procedure, a compression force is then applied on the product in order to set it in the fibrous mass. A device for the operation of the procedure is made of two cylinders (20, 30) connected by a belt (40). The teeth of the first cylinder (23) fashion the impressions; the perforations (41) of the belt permit the localization of the powder in the impressions, and the teeth of the second cylinder (33) enable its setting. The procedure concerns especially the incorporation of superabsorbent material in the fiber padding of disposable hygiene articles. |
