ABSTRACT:
Liquidproof seams are formed between laminates, most preferably those having a complex textile structure on the sealing side of the laminate, where at least a portion of the complex textile in the sealing region is removed, such as by skiving, to reduce the thickness in the seam, or sealing region, prior to the creation of a durably sealed liquidproof seam.
