Abstract
Aspects of the present disclosure relate to tucking opposing side panels into a chassis of a pant diaper. The apparatuses and methods may utilize one or more conveyors that advance the chassis along a machine direction. Each conveyor may have a vacuum zone that applies a vacuum force to hold the chassis. The chassis may be positioned between a first conveyor having a first vacuum zone and a second conveyor having a second vacuum zone. The conveyors may apply opposing vacuum forces to hold the first waist region apart from the second waist region while the chassis advances in the machine direction toward a tucking device. The tucking device may discharge air to push the side panels into the chassis and create longitudinal fold lines along edges of the absorbent core of the diaper.
