ABSTRACT:
An expandable collapsible product is made by providing a pleated sheet (8,10) having legs (20) which are made by securing two parts of a fold (17) together. Two sheets are combined by securing the end of a leg (20) to a crease (16) or a leg (20) of an opposite sheet. The sheet material is folded to preferably provide alternating taller folds (17) and shorter folds (16), and the taller folds are modified to provide the legs (20) by gluing parts of the taller folds (17) together. Gluing is accomplished by moving glue heads across the sheet at high velocity through the use of linear motors. The glue lines are heated after being laid down by the use of electro-magnetic radiation, preferably from a high-powered laser. The finished product is used as insulated window coverings, or the like.
