1. A method for assembling disposable absorbent articles, each absorbent article comprising a chassis, a first side panel, and a second side panel, each chassis defining a longitudinal axis and a lateral axis, the chassis having a first waist region, a second waist region, and a crotch region positioned longitudinally between the first and second waist regions, the method comprising:
advancing a first continuous web in a machine direction to a drum, wherein the drum rotates about a rotation axis, and wherein the drum comprises a first lane of folding devices and a second lane of folding devices in an outer surface of the drum, wherein the first lane of folding devices are offset from the second lane of folding devices in a direction parallel with the rotation axis, wherein each folding device comprises: a chassis support member, a chassis folding member, a first side panel folding member, and a second side panel folding member; positioning the first continuous web on the chassis support member, the first side panel folding member, and the second side panel folding member of the first lane of folding devices; advancing a second continuous web in the machine direction to the drum; positioning the second continuous web on the chassis support member, the first side panel folding member, and the second side panel folding member of the second lane of folding devices; advancing a first chassis in the machine direction to the first lane of folding devices; positioning the first waist region of the first chassis on the chassis support member and the second waist region of the first chassis on the chassis folding member; advancing a second chassis in the machine direction to the second lane of folding devices; positioning the first waist region of the second chassis on the chassis support member and the second waist region of the second chassis on the chassis folding member; connecting the first waist region of the first chassis with the first continuous web; connecting the first waist region of the second chassis with the second continuous web; cutting the first continuous web into discrete lengths of belt material, wherein a portion of the discrete length of belt material supported by the first side panel folding member defines a first side panel, and a portion of the discrete length of belt material supported by the second side panel folding member defines a second side panel; cutting the second continuous web into discrete lengths of belt material, wherein a portion of the discrete length of belt material supported by the first side panel folding member defines a first side panel, and a portion of the discrete length of belt material supported by the second side panel folding member defines a second side panel; pivoting the chassis folding member relative to the chassis support member to position the first and second waist regions of the first chassis into a face-to-face relationship; pivoting the chassis folding member relative to the chassis support member to position the first and second waist regions of the second chassis into a face-to-face relationship; pivoting the first side panel folding member relative to the chassis support member to position the first side panel into contact with the second waist region of the first chassis; pivoting the first side panel folding member relative to the chassis support member to position the first side panel into contact with the second waist region of the second chassis; pivoting the second side panel folding member relative to the chassis support member to position the second side panel into contact with the second waist region of the first chassis; pivoting the second side panel folding member relative to the chassis support member to position the second side panel into contact with the second waist region of the second chassis; connecting the first and second side panels with the second waist region of the first chassis to form a diaper pant; and connecting the first and second side panels with the second waist region of the second chassis to form a diaper pant. |
