ABSTRACT:
An improved emergency slide evacuation device wherein a second ply substantially parallels a sliding ply of the emergency slide evacuation device but remains substantially unattached to the sliding ply except for edge portions of the second ply whereby the second ply supports the sliding ply in the event of tears or rips in the sliding ply but remains at least partially isolated from the forces being applied to the sliding ply to effect tearing or ripping. The improvement finds use particularly in the fabrication of aircraft evacuation slides.
