Abstract
A method for forming an absorbent article including a first absorbent core and a second absorbent core which are superposed on each other, includes feeding a first supporting web along a first feed path in a first feed direction; placing a succession of first absorbent cores on the first supporting web at a preset spacing; feeding a second supporting web along a second feed path in a second feed direction; placing a succession of second absorbent cores on the second supporting web at the preset spacing; coupling the first supporting web to the second supporting web such that each first absorbent core is coupled to a corresponding second absorbent core in a composite web including the succession of first absorbent cores and the succession of the second absorbent cores interposed between the first supporting web and the second supporting web.
