Definitions

  • Each band is made of a one-way stretch fabric. Either woven or needled fabric may be used, but it is important to the invention that the stretch of the fabric be in the direction in which the bands are woven together. For example, the direction of stretch of horizontal bands 18 and 22 is horizontal, while the direction of stretch of vertical bands 20, 24 is vertical.
  • any suitable woven or needled elastic fabric with a one-way stretch may be suitable for use in the present invention, it should be appreciated that the fabric should be such that stretching the fabric does not cause the individual fibers to separate to such an extent that light is transmitted through the band.
  • the double thickness formed by weaving bands 18, 20, 22 and 24 together in a simple basket weave design adds a safety factor to insure that no light is transmitted through the covering of the loader openings when the individual bands are stretched as a hand is inserted. it
