Problems solved by technology

This can lead to wrinkling of the pouch
Additionally, wrinkling of the web can interfere with the formation of transverse seals so that the materials are not completely sealed together, resulting in leaky pouches

Embodiment Construction

[0033] Methods and apparatus for pleating or otherwise forming webs are described herein. As used herein, the term "forming" refers to changing the configuration of a planar web in a controlled manner. The term "forming" includes, but is not limited to: forming a web but not necessarily forming folds in said web; at least partially folding a web without forming creases in the web or folding the web itself in half; folds onto itself; and forms a plurality of juxtaposed folds or pleats in a web. The methods and apparatus have a variety of applications.

[0034] figure 1 is an example of a web 10 that is passed over a prior art folding plate to form individual pleats in the moving web. Arrows indicate the direction of travel of the web, which will be referred to as the machine direction (or "MD"). T The direction perpendicular to the machine direction in the plane of the incoming unfolded web is referred to as the cross direction (or "CD"). For reasons explained below, figu...
