    摘要: 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.

    摘要: A thermal insulating curtain, especially for use in greenhouses, which comprises a plurality of superimposed uni-directionally arranged tubular members with a common slat-like partition between each two adjacent ones of said tubular members. Each of these tubular members along its two opposite sides has a folding crease to allow collapsing said tubular members to thereby permit collapsing the entire curtain in a manner of a blind or to roll the curtain up in the manner of a shade.
