18. Apparatus for forming folds in a foldable material in a continuous
operation, the apparatus comprising a frame adapted for receiving a moving
web of the foldable material through the apparatus along a path, and a
plurality of skis mounted on the frame and adapted to engage the web of
foldable material for use in forming folds in the engaged web as the web of
foldable material moves through the apparatus along the path, and a material
guide for engaging the web of foldable material to form the material in
cooperation with at least one of the skis to produce at least one of the folds.
34. Apparatus for forming folds in a foldable material in a continuous
operation, the apparatus comprising a frame adapted for receiving a moving
web of the foldable material through the apparatus along a path, and a
