Abstract
An apparatus for fabricating an elastic nonwoven material generally includes a first bonding module, a second bonding module positioned in close proximity to the first bonding module, and a pinching device. The first bonding module and the second bonding module are adapted to bond at least one elastic strand of the elastic nonwoven material. The pinching device is adapted to limit a snap-back potential of the at least one elastic strand if the at least one elastic strand becomes severed during bonding.
