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 prefereably 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.

Abstract: A method of lining a pipeline 24 intended to carry gas, oil, water, sewage or chemicals in which a cross-linked polymeric liner pipe 10, which has been reduced from its original diameter to a lesser diameter or to a shape of reduced maximum dimension, is pulled through the pipeline 24. The lesser diameter is less than the least inner diameter of the pipeline 24. After the liner pipe 10 has been fully pulled through, the pipe liner 10 is heated by means of a source 60 of visible or infrared radiation forming part of a pig assembly 50 to cause it to revert to the pipeline. The pig assembly or assemblies are stationary at zones 70 where service connections are to be made. Subsequently, the remaining liner pipe 10 is reverted by pulling the source 60 through the liner pipe 10.
