Abstract
Aspects of the present disclosure relate to tucking opposing side panels into a chassis of a diaper pant. 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 vacuum forces are then removed from the waist regions as the tucking device pushes the side panels toward each other. Pushing the side panels toward each other causes the inner surfaces of the waist regions to simultaneously move toward each other.
