## Abstract

A method of folding a pant-like disposable absorbent garment includes providing a garment defining first and second waist side regions, a waist center region positioned therebetween, and a crotch region longitudinally below the waist center region. In particular embodiments, the method further includes folding the garment along a transversely extending fold line so as to bring the crotch region into superposed relation with the waist center region; providing a chute having a floor and first and second side walls; urging the garment into the chute; and, while the garment is in the chute, folding the garment along longitudinally extending first and second fold lines so as to position the first and second waist side regions over the waist center region. The first and second fold lines are adjacent the first and second side walls, respectively.

## Claims

### Claim 1

A method of folding a pant-like disposable absorbent garment, the method defining a machine direction, a cross-machine direction, and a vertical direction generally perpendicular to both the machine direction and the cross-machine direction, the machine direction and the cross-machine direction together defining a transport plane, the method comprising:
providing said garment, said garment having a waist opening and two leg openings, said garment defining a longitudinal direction and a transverse direction, said garment defining a first waist side region adjacent a first side edge, a second waist side region adjacent a second side edge, a waist center region positioned transversely between the first waist side region and the second waist side region, and a crotch region longitudinally adjacent the waist center region, the garment further including an absorbent core;
providing a chute, the chute comprising a first side wall and a second side wall, the chute defining a chute width extending from the first side wall to the second side wall, the chute defining a first end having a first opening and a second end having a second opening, the chute extending from the first end to the second end in the vertical direction;
transporting the garment in the machine direction, such that the longitudinal and transverse directions of the garment lie substantially within the transport plane;
positioning the garment over the first opening of the chute;
urging the garment into the chute;
transporting the garment in the vertical direction within the chute; and
folding the garment along a longitudinally extending first fold line so as to position the first waist side region over the waist center region, the first fold line being adjacent the first side wall, and folding the garment along a longitudinally extending second fold line so as to position the second waist side region over the waist center region, the second fold line being adjacent the second side wall, wherein both such folding steps occur while the garment is in the chute.

### Claim 2 (depends on 1)

The method of claim 1, wherein the absorbent core defines a longitudinally extending first core side edge and a longitudinally extending second core side edge, the core defining a maximum core width, wherein the maximum core width exceeds the chute width, such that the first fold line and the second fold line each extend into the absorbent core.

### Claim 3

A method of folding a pant-like disposable absorbent garment, the method defining a machine direction, a cross-machine direction, and a vertical direction generally perpendicular to both the machine direction and the cross-machine direction, the machine direction and the cross-machine direction together defining a transport plane, the method comprising:
providing said garment, said garment having a waist opening and two leg openings, said garment defining a longitudinal direction and a transverse direction, said garment defining a first waist side region adjacent a first side edge, a second waist side region adjacent a second side edge, a waist center region positioned transversely between the first waist side region and the second waist side region, and a crotch region longitudinally adjacent the waist center region, the garment further including an absorbent core;
providing a chute, the chute comprising a first side wall and a second side wall, the chute defining a chute width extending from the first side wall to the second side wall, the chute defining a first end having a first opening and a second end having a second opening, the chute extending from the first end to the second end in the vertical direction;
transporting the garment in the machine direction, such that the longitudinal and transverse directions of the garment lie substantially within the transport plane;
positioning the garment over the first opening of the chute;
urging the garment into the chute;
transporting the garment in the vertical direction within the chute;
folding the garment along a longitudinally extending first fold so as to position the first waist side region over the waist center region, the first fold line being adjacent the first side wall, and folding the garment along a longitudinally extending second fold line so as to position the second waist side region over the waist center region, the second fold line being adjacent the second side wall, wherein both such folding steps occur while the garment is in the chute; and
folding the garment along a transversely extending fold line so as to bring the crotch region into superposed relation with the waist center region, wherein said folding the garment along the transversely extending fold line occurs before folding the garment along the first and second fold lines.

### Claim 4

A method of folding a pant-like disposable absorbent garment, the method defining a machine direction, a cross-machine direction, and a vertical direction generally perpendicular to both the machine direction and the cross-machine direction, the machine direction and the cross-machine direction together defining a transport plane, the method comprising:
providing said garment, said garment having a waist opening and two leg openings, said garment defining a longitudinal direction and a transverse direction, said garment defining a first waist side region adjacent a first side edge, a second waist side region adjacent a second side edge, a waist center region positioned transversely between the first waist side region and the second waist side region, and a crotch region longitudinally adjacent the waist center region, the garment further including an absorbent core;
providing a chute, the chute comprising a first side wall and a second side wall, the chute defining a chute width extending from the first side wall to the second side wall, the chute defining a first end having a first opening and a second end having a second opening, the chute extending from the first end to the second end in the vertical direction;
transporting the garment in the machine direction, such that the longitudinal and transverse directions of the garment lie substantially within the transport plane;
positioning the garment over the first opening of the chute;
urging the garment into the chute;
transporting the garment in the vertical direction within the chute; and
folding the garment along a longitudinally extending first fold line, the first fold line being adjacent the first side wall, and folding the garment along a longitudinally extending second fold line, the second fold line being adjacent the second side wall, wherein both such folding steps occur while the garment is in the chute.
