THE TOP SHEET FOR AN ABSORBENT ARTICLE HAVING A PLURALITY OF FUSED COMPRESSED SECTIONS CAN BE PRODUCED BY A PROCESS WHEREIN A TOP SHEET IS SITUATED BETWEEN A MEMBER WITH MULTIPLE PROTRUSIONS (10) AND A MEMBER WITH MULTIPLE RECESSES (11) THAT ENGAGE WITH THE MULTIPLE PROTRUSIONS, AND THE PROTRUSIONS ARE PRESSED INTO THE RECESSES.
