Abstract:
1. A method for joining at least two fabric layers, comprising the steps: providing at least two fabric layers; saturating at least facing surfaces of the fabric layers with an adhesive; providing an adhesive film between the fabric layers; applying heat and pressure to said at least two fabric layers so as to form a joint thereof; monitoring the quality of said joint for voids in the adhesive; and adjusting at least one joint formation parameter whereby said voids in the adhesive between the joined fabric layers are eliminated and avoided, said joint formation parameters comprising a group including adhesive film thickness, fabric layer weave openness, adhesive heating temperature, pressure applied to the joint during formation, a time that the adhesive is maintained near its melting point, and a time that pressure is applied to the fabric layers.
