A method for aperturing a laminate. The first step is to provide a laminate having at least one nonwoven web of thermoplastic fibers and at least one elastic member. The laminate is forwarded through a pressure biased nip having a relief patterned nip defining member having a plurality of pattern elements and a nip defining anvil member. The nip defining members are biased towards each other with a predetermined pattern-element loading. Each nip defining member is heated to a temperature that is sufficiently above the melt temperature of the thermoplastic fibers of the nonwoven web and above the melt temperature of the elastic member to enable aperturing of the laminate.
