  • Patent number: 6168496
    Abstract: A method is provided for producing a fabric-covered spring toy having a helical body which is decorated both on its outside and on its confronting helical surfaces. In the method, a fabric tube is everted using a lanyard to pull one end of the tube through the tube center to produce the fabric tube. Everting produces a tube with a decorative surface on the outer face. The resulting fabric covered spring body can be sewn to other fabric structures such as simulated animal body parts, for incorporation into an animal-like product having a semi-soft, flexible body.
