Abstract
A method and apparatus for folding and engaging side panels of a training pant are provided. The training pant comprises a leading portion, a trailing portion, a central portion, and a first pair of side panels and a second pair of side panels attached to the central portion. The central portion of the training pant is folded about a transverse axis to form a folded training pant. Portions of the first pair of side panels and second pair of side panels are engaged while the central portion of the folded training pant is received by at least one recessed seat. The at least one recessed seat is located on at least one of a first belt and a second belt of a conveyance system.

A method of engaging side panels of an absorbent article comprising:
- providing a training pant comprising a leading portion, a trailing portion, and a central portion extending in a longitudinal direction between the leading portion and the trailing portion, the training pant comprising a first pair of side panels attached to the central portion proximal one of the leading portion and the trailing portion of the training pant and a second pair of side panels attached to the central portion proximal another of the leading portion and the trailing portion of the training pant, wherein the first pair of side panels each comprise a first fastening region and the second pair of side panels each comprise a second fastening region;
- folding the central portion of the training pant about a transverse axis orthogonal to the longitudinal direction to form a folded training pant;
- and
- engaging at least a portion of the first fastening regions and at least a portion of the second fastening regions while the central portion of the folded training pant is received by at least one recessed seat, wherein the at least one recessed seat is located on at least one of a first belt and a second belt of a conveyance system.
An apparatus for preparing a folded training pant comprising:
- a conveyance system comprising:
- a first conveying device comprising a first belt;
- a second conveying device comprising second belt, wherein the first conveying device and the second conveying device are each configured such that the first belt and the second belt form at least one parallel rectilinear branch;
- and
- a folding nip, situated between the respective rectilinear branches of the first belt and the second belt and adapted to fold a training pant about a transverse axis orthogonal to a longitudinal direction to form a folded training pant;
- wherein at least one of the first belt and the second belt further comprises at least one recessed seat configured to receive a central portion of the folded training pant.
An apparatus for preparing a folded training pant comprising:
- a training pant assembly system configured to prepare a training pant comprising a leading portion, a trailing portion, and a central portion extending in a longitudinal direction between the leading portion and the trailing portion, the training pant comprising a first pair of side panels attached to the central portion proximal one of the leading portion and the trailing portion of the training pant and a second pair of side panels attached to the central portion proximal another of the leading portion and the trailing portion of the training pant, wherein the first pair of side panels each comprise a first fastening region and the second pair of side panels each comprise a second fastening region;
- a conveyance system comprising:
- a first conveying device comprising a first belt;
- a second conveying device comprising a second belt;
- at least one parallel rectilinear branch between the first belt and the second belt;
- and
- a folding nip, situated between the respective rectilinear branches and adapted to fold the training pant about a transverse axis orthogonal to the longitudinal direction to form a folded training pant ;
- wherein at least one of the first belt and the second belt further comprises at least one recessed seat configured to receive the central portion of the folded training pant.
