    摘要: A laminated stretch cushion strap assembly having a stretchable cover, a stretchable cushion filler and a stretchable bottom or bottom fabric. The cover includes a stretchable top fabric, a first adhesive web layer positioned on one side of the top fabric and a stretchable base layer positioned on the first adhesive layer on a side opposite that of the top fabric. The stretchable bottom fabric forms with the cover an enclosure. The stretchable cushion filler is adapted to be completely enclosed within the enclosure. The stretchable cushion filler has a first cushion layer, and adhesive for securing during lamination the cover to the stretchable cushion filler, and the cushion filler to the stretchable bottom fabric. The adhesive is a second adhesive web layer positioned between the stretchable base layer and the first cushion layer to secure the cushion filler to the cover, and a third adhesive web layer positioned on the first cushion layer to secure the bottom fabric to the cushion filler. The components of the cushion strap assembly are laminated together completely by heat and adhesive. The present invention also provides a method and device for making this cushion strap.
