METHOD OF PRODUCING FLOW LINES IN A SANITARY PRODUCT

摘要

A method of making sanitary products giving a high wearing comfort is disclosed. The method comprises steps of forming three superposed interconnected layers (14, 15, 16). The outer layers (14, 16) are made of hydrofobic fibers and the intermediate layer (15) is made of hydrofilic fibers. The top sheet of the sanitary product is constituted by the layer (16), the back sheet is constituted by the layer (14) and the core is constituted by the layer (15). In this intermediate layer (15) flow lines (33) are made by means of a first embossing roller (31) having a pattern of raised ridges. The ridges provide a pattern (38) of groove-formed flow lines (33) allowing a body liquid to be distributed in the core (29) by flowing through the groove-formed flow lines (19).
