Abstract
Slide fasteners (zippers) used for certain applications function better if the zipper tape can stretch in the lateral direction. When a zipper is used to close certain articles such as luggage, boots, or certain garments, it can be difficult to easily and fully close a zipper if there is a significant lateral load pulling at the tapes perpendicular to the direction that the slider is pulled. By using a zipper that includes a zipper tape that stretches in the lateral direction, it is possible to more easily close such articles while maintaining a neat appearance of the zipper on the article.
