Abstract
An apparatus for fabricating an elastic nonwoven material generally includes a first bonding module and a second bonding module. The second bonding module is positionable in close proximity to the first bonding module for receiving a first nonwoven fabric, a second nonwoven fabric, and at least one elastic strand therebetween. The second bonding module has a face with a width dimension and a circumferential axis and is rotatable about a rotation axis. The face has a plurality of ridges includes a first ridge and a pair of second ridges positioned on opposing sides of the first ridge along the circumferential axis. The first ridge defines a plurality of interspaced lands and notches, and the second ridges are configured to sever the at least one elastic strand when in close proximity to the first bonding module.
