Abstract
Aspects of the methods according to the present disclosure relate to the fabrication of diaper pants wherein discrete chassis are advanced in a machine direction such that the longitudinal axis is parallel with the machine direction. Discrete lengths of elastic belt materials are then connected with the first waist region of a first advancing chassis and the second waist region of a second advancing chassis. The lengths of elastic belt materials are cut along the cross-direction between the discrete chassis forming a first elastic belt and a second elastic belt; the chassis are subsequently folded; and the first and second elastic belts disposed on the chassis are bonded together to create a discrete diaper pant. This apparatus and process configuration forms a continuous web of articles formed by intermittently spaced chassis and intermittently spaced elastic belts bridging the gap between the intermittently spaced chassis.
