ABSTRACT:
An attachment structure for a load-bearing fabric including an expandable carrier secured to an un-stretched load-bearing fabric. To attach the carrier to a support frame, the carrier and fabric are stretched together to desired shape and secured to the frame. An indexing system registers the carrier and frame and optionally stretches the fabric a predetermined amount. The present invention also provides a lip that flexes in one direction and maintains the fabric in a stretched condition in another. A tool that joins the carrier and frame generally includes a drive roller and a primary roller adapted to move toward one another and join a carrier and the support frame disposed therebetween. The tool may include alignment rollers near the primary and drive rollers to track along and align the carrier and frame.
