A distinctive technique for creating a shaped article (90, 100) includes a pivoting of a first portion (56) of a cooperating web layer (26) substantially about a first joining region (40) to lie laterally adjacent to a first portion (52) of a primary web layer (24). The cooperating web layer (26) has been positioned in a superposed facing relation with the primary web layer (24) with the primary web layer having a first and second, lateral side edge regions (32, 34), and the cooperating web layer having third and fourth, lateral side edge regions (36, 38). The first side edge region (32) of the primary web layer (24) has been synchronized to the third side edge region (36) of the cooperating web layer (26) along the first joining region (40), and the second side edge region (34) of the primary web layer (24) has been synchronized to the fourth side edge region (38) of the cooperating web layer (26) along a second joining region (42) to provide a synchronized laminated web (44). The laminated web has been separated along a serpentine division line (46) to provide a first composite web (48) and at least a second composite web (50). The first composite web (48) has the first portion (52) of the primary web layer (24) combined with the first portion (56) of the cooperating web layer (26), and the second composite web (50) has a second portion (54) of the primary web layer (24) combined with a second portion (58) of the cooperating web layer (26).
