Abstract:
1. A multi-layer coated fabric comprising: a first coated fabric layer bonded with a second coated fabric layer and having an inner welded seam of controlled size or shape determined at least in part by the application of welding elements to the outer surfaces of said first and second coated fabric layers, wherein said first and second coated fabric layers each comprises a fabric formed from a monoaxially drawn polymer tape, wherein each of said first and second fabric layers includes a sealing layer formed from a thermoplastic synthetic material, the melting point of which is below a crystallite melting point of a fabric tape material of the monoaxially drawn polymer tape, wherein said multi-layer coated fabric is formed by placing said first and second coated fabric layers adjacent to each other with the sealing layers facing each other followed by forming said welded seam of controlled size or shape by applying heat to outer surfaces of said first and second coated fabric layers by welding elements heated to a temperature below the crystallite melting point of the fabric tape material until the two adjacent sealing layers melt together.
