Abstract:
A method for forming a leakproof seal between fabric composites, comprising the steps of:(a) finishing first and second fabric sections to have matching fabric edges;(b) overlaying a first synthetic membrane parallel with the first fabric section with the first synthetic membrane extending beyond either side of the matching edge of the first fabric section;(c) overlaying the first fabric section parallel with a thermoplastic joiner film extending beyond either side of the matching edge thereof;(d) overlaying the joiner film parallel with the second fabric section with the matching edge thereof in register with the matching edge of the first fabric section;(e) overlaying the second fabric section parallel with a second synthetic membrane extending beyond either side of the matching edges;(f) welding adjacent the matching fabric edges to form a seam securing the fabric sections to the joiner film inside the matching edges and securing the synthetic membrane to the joiner film outside the matching edges.
