Abstract
A method and system for fabricating an article using a first bonding module having a first bonding module face and a second bonding module having a second bonding module face include supplying a first non-woven fabric to at least one of the first bonding module face and the second bonding module face, and supplying a plurality of elastic strands to a surface of the first non-woven fabric. The method and system further include entrapping a first elastic strand between a first pair of adjacent bonds in a first row in the first non-woven fabric, entrapping a second elastic strand between a second pair of adjacent bonds in the first row, and creating a third pair of adjacent bonds in the first row free of elastic bands therebetween. The third pair of adjacent bonds is located between the first pair of adjacent bonds and the second pair of adjacent bonds.
