摘要: The method includes providing a thermoplastic web having mechanical fastening elements and a nonlinear line of weakness that extends predominantly in a first direction and demarcates nonlinear edges of two sub-webs but does not sever the thermoplastic web. The method further includes severing the thermoplastic web at the nonlinear line of weakness into the two sub-webs and joining the two sub-webs to a carrier to form the laminate. The two sub-webs are separated in a second direction perpendicular to the first direction. Severing the thermoplastic web and joining the two sub-webs to the carrier are carried out in-line without offsetting the two sub-webs in the first direction.
