INCORPORATION OF PULVERULENT PRODUCTS INSIDE A FIBRE MATTRESS

摘要

The method comprises the local pressing of the fibre mattress by means of a tool having a predetermined profile, and the deposition of the pulverulent product inside the print made by the tool. According to a further feature of the method, there is then applied a compression force to the product in order to crimp it into the fibre mass. A device for implementing the method comprises two cylinders (20, 30) connected by a belt (40). The teeth (23) of the first cylinder form the prints, the holes (41) of the belt enable to position the deposit of powder into the prints and the teeth (33) of the second cylinder are intended to crimp the powder. The method relates in particular to the incorporation of superabsorbent material into the fibre mattress of disposable hygienic articles.
