Abstract
A process for forming a strong, pressure-tight joint between fabric substrates includes coating each substrate with polyurethane on one side, superimposing the fabric substrates so that the polyurethane layers are together, welding elongated regions of the polyurethane together under heat and pressure and sewing through the weld. The edge is then folded over and bonded to itself and the material is spread out. The resulting material can be bonded to a sole to form a waterproof, lightweight boot.
