A method and apparatus for folding garments is suitable for use with garments having discrete mechanical fastening components and suitable for the manufacture of prefastened and refastenable garments. The garments or other discrete articles define leading and trailing halves with opposed side panels. A chassis portion and side panels of the garments can be controlled during folding by providing a three piece vacuum puck design and/or a channeled transfer plate as well as a layer of air under the leading side panels.

1. A method of folding garments, comprising:creating a folding nip between first and second folding conveyors; transporting a plurality of discrete articles on the first folding conveyor toward the folding nip, each discrete article comprising a chassis and defining a leading half including opposed leading side panels, a trailing half including opposed trailing side panels, and an interconnecting region disposed between and interconnecting the leading and trailing halves; guiding the leading half onto a transfer plate using a product control drum having at least one vacuum puck, the at least one vacuum puck comprising multiple pieces; moving the interconnecting region into the folding nip; and advancing the leading and trailing halves into the folding nip. 2. The method of claim 1, wherein the leading half and the trailing half comprise mechanical fastening components.3. The method of claim 1, wherein the at least one vacuum puck comprises at least three pieces.4. The method of claim 3, wherein one of the at least three pieces supports the chassis and two of the at least three pieces support the opposed leading side panels of each discrete article.5. The method of claim 1, further comprising engaging fastener components on the leading side panels and the trailing side panels of each discrete article.6. The method of claim 1, wherein an amount of vacuum pulled by each of the multiple vacuum puck pieces is controlled separately.7. The method of claim 1, further comprising providing at least one fluid stream to control the leading side panels while the leading half is over the transfer plate.8. The method of claim 1, wherein guiding the leading half onto a transfer plate comprises supplying high pressure air.9. A method of folding garments, comprising;creating a folding nip between first and second folding conveyors; transporting a plurality of discrete articles on the first folding conveyor toward the folding nip, each discrete article comprising a chassis and defining a leading half including opposed leading side panels, a trailing half including opposed trailing side panels, and an interconnecting region disposed between and interconnecting the leading and trailing halves, the leading half and the trailing half comprising mechanical fastening components; guiding the leading half onto a channeled transfer plate; moving the interconnecting region into the folding nip; and advancing the leading and trailing halves into the folding nip. 10. The method of claim 9, further comprising straightening the leading side panels prior to advancing the leading and trailing halves into the folding nip.11. The method of claim 9, wherein the channeled transfer plate comprises at least three regions.12. The method of claim 9, further comprising aligning each discrete article by contacting the discrete article with one of the folding conveyors in front of the folding nip.13. The method of claim 12, further comprising simultaneously moving the leading side panels over the transfer plate.14. The method of claim 12, further comprising holding the discrete article on the second folding conveyor by vacuum.15. A method of folding garments, comprising:creating a folding nip between first and second folding conveyors; transporting a plurality of discrete articles on the first folding conveyor toward the folding nip, each discrete article comprising a chassis and defining a leading half including opposed leading side panels, a trailing half including opposed trailing side panels, and an interconnecting region disposed between and interconnecting the leading and trailing halves; guiding the leading half onto a transfer plate, the transfer plate providing a layer of air under the discrete articles; moving the interconnecting region into the folding nip; advancing the leading and trailing halves into the folding nip. 16. The method of claim 15, wherein the layer of air is provided by at least one of the group consisting of air jets, air bars, and air knives.17. The method of claim 15, wherein the layer of air supports the leading side panels.18. The method of claim 1, wherein the folding nip is formed by at least one timed vacuum roll.19. The method of claim 18, wherein vacuum of the vacuum roll can be turned at least one of on and off quickly.20. The method of claim 9, wherein the folding nip is formed by at least one timed vacuum roll.21. The method of claim 20, wherein vacuum of the vacuum roll can be turned at least one of on and off quickly.22. The method of claim 15, wherein the folding nip is formed by at least one timed vacuum roll.23. The method of claim 22, wherein vacuum of the vacuum roll can be turned at least one of on and off quickly.
