1. A method for assembling disposable diaper pants, each diaper pant comprising a chassis, a first side panel, and a second side panel, each chassis having a longitudinal axis and a lateral axis, and comprising a first waist region longitudinally opposed to a second waist region, and a crotch region
1. A method for assembling disposable diaper pants, each diaper pant comprising a chassis, a first side panel, and a second side panel, each chassis having a longitudinal axis and a lateral axis, and comprising a first waist region longitudinally opposed to a second waist region, and a crotch region longitudinally intermediate of the first and second waist regions, each chassis further comprising: a topsheet, a backsheet, and an absorbent core disposed between the topsheet and the backsheet, the method comprising the steps of: providing a chassis;folding the chassis along the lateral axis to position the first waist region into a facing relationship with the second waist region;providing first and second side panels;connecting the first and second side panels with the first waist region and the second waist region of the folded chassis along four seams to form a waist opening and a pair of leg openings; andwherein the four seams are substantially simultaneously produced. 2. The method of claim 1, further comprising forming a plurality of ears. 3. The method of claim 2, further comprising folding the plurality of ears before connecting the side panels with the chassis. 4. The method of claim 3, wherein the side panels overlay the folded ears. 5. The method of claim 1, further comprising forming folded side panel edges by folding a portion of each side panel. 6. The method of claim 5, wherein the folded side panel edges of the first and second side panels overlay the chassis when the side panels are attached to the chassis. 7. The method of claim 5, wherein the chassis overlays the folded side panel edges when the side panels are attached to the chassis. 8. The method of claim 1, wherein the chassis is folded by a folding device having articulating arms. 9. The method of claim 8, wherein the folding device includes gripping portions on the articulating arms, the gripping portions including a vacuum to hold the chassis on the gripping portions. 10. The method of claim 9, wherein the folding device is mounted on a main drum and the side panels are delivered to the folding device by a first auxiliary drum and a second auxiliary drum, the first and second auxiliary drums being axially aligned with the main drum and extending laterally from the main drum on opposite sides thereof, each of the auxiliary drums having a smaller diameter than the main drum. 11. The method of claim 10, wherein the first and second auxiliary drums include at least one articulating paddle. 12. The method of claim 11, wherein the articulating paddle rotates about an axis that is perpendicular to an axis of rotation of the respective auxiliary drum. 13. The method of claim 1, wherein the chassis is folded by a mandrel. 14. The method of claim 13, wherein the mandrel includes an outer surface and an inner surface, the outer and inner surfaces having a cross-sectional shape that is an arc of a circle. 15. The method of claim 14, wherein a radius of curvature of the outer surface is larger than a radius of curvature of the inner surface. 16. The method of claim 13, wherein at least a portion of the mandrel includes a vacuum system. 17. The method of claim 13, wherein the side panels are disposed on the mandrel prior to the mandrel folding the chassis. 18. The method of claim 1, wherein the seams are formed by one of adhesives, cohesives, hook and loop fasteners, thermal bonding, pressure bonding, ultrasonic bonding, or a combination thereof.
