  • Patent number: 5669320
    Abstract: An adjustable template for maneuvering a textile product. The template includes a template base with several template shoes movably mounted along the sides of the base. The position of the template shoes with respect to the template base is adjusted in response to the detection of the length and the width of the textile product such that when the template is positioned on the product, each template shoe is positioned at a predetermined distance from a lateral edge of the textile product.

  • Patent number: 5619942
    Abstract: A method and apparatus for manufacturing a textile product from a continuous strip of material having borders defining discrete panels. The apparatus pulls the strip along a pre-determined path. As the strip is advanced, the border of a panel is detected. Based upon the distance the panel is advanced after the detection of the border, the length of each panel is determined while the width of each panel is measured. Each panel is then cut from the strip and maneuvered along a calculated path for finishing based upon the determination of length and width.

  • Patent number: 4893574
    Abstract: In a method and apparatus for constructing pillowcases, upper and lower layers of fabric are conveyed along separate paths with their obverse surfaces facing upwardly. Cuffs are formed along one longitudinal edge of each layer. The upper layer of fabric is then reversed to an obverse-side down orientation, and the upper and lower layers of fabric are superimposed with their obverse surfaces mutually facing and their cuffed lateral edges mutually corresponding. The superimposed upper and lower layers of fabric are then stitched together along the lateral edge opposite the cuffed lateral edge. Next, a length of the superimposed upper and lower layers of fabric is cut to a length equal to the desired width of a finished pillowcase. The resulting rectangular workpiece comprises upper and lower panels of fabric stitched together along one transverse edge and cuffed at their opposite transverse edge.
