Abstract
The procedure consists in compressing locally the fiber padding by means of a specifically profile tool, and in placing the powdery product in the impression left by the tool. 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.
