PURPOSE: A method of joining at least two webs is provided which enables the joining of thick, porous webs in an extremely effective manner, minimizes process time and improves machine efficiency due to reduced wear and friction. CONSTITUTION: A porous webs (11,12) comprise meltable components, being arranged in an adjacent manner to form a web structure (10), the web structure (10), comprising outer surfaces (13,14) and an area of overlap between the webs (11,12). The method characterized by the steps of: 1) sufficiently heating a fluid to enable at least a partial melting of the meltable components; 2) directing a high speed jet of the heated fluid towards at least one of the outer surfaces (13,14); 3) allowing the fluid to penetrate the webs (11,12) at discrete locations; and 4) allowing the fluid to circulate in the webs (11,12) to at least partially melt the meltable components. Also a disposable absorbent article is made according to this method. |
