Roman shade and method for making same

Abstract From the Canadian patent

The specification describes a shade component for a Roman shade and a method of making same from plastic sheet material having a heat sealable characteristic. The sheet material is folded to form transverse, horizontally extending pleats which are heat sealed together to permanently secure them. A bottom hem is formed by folding and heat sealing a bottom portion of the sheet material. The terminal end of the sheet material may be joined to a bottom horizontally extending pleat, either within or adjacent the pleat so that, the bottom pleat and hem are formed at the same time. Apertures through which shade pull strings are guided are, provided in the pleats.
