Abstract: The present invention is an improved method for automatically generating chenille filled embroidery stitch patterns and/or chain stitching in a computer aided design system in which the shape to be filled is a complex polygon. The medial axis of the polygon is determined, concentric polygons are then constructed and sorted and spirals are placed along the polygons with stitches being placed along the spirals. For chain stitching, rather than placing spirals, the chain stitches are placed on the perimeter of the concentric polygons.

Abstract: A laminated film including at least one first layer of a polymeric material which has a starchy matrix and is insoluble in water or at most expands in water, constituted by destructured starch and an olefinic copolymer and a second layer of a hydrophobic material adhering to the first. Applications are for the packaging of food products and for colostomy containers, for which a very effective barrier against gases and vapours is needed.
