ABSTRACT:
A water-resistant slide fastener has a pair of water-resistant transversely stretchable stringer tapes having reinforced marginal edge portions, respectively, each including an elastically deformable core tape, and a pair of rows of coupling elements mounted on the reinforced marginal edge portions, respectively, and engageable with each other across a central axis. The reinforced marginal edge portions have a pair of confronting edges projecting toward each other beyond the central axis when the rows of coupling elements are out of mutual engagement. Each of the stringer tapes has a woven or knitted foundation tape and a soft sealing layer on the foundation tape. Each of the reinforced marginal edge portions includes a folded marginal tape edge portion with the soft sealing layer disposed outside. The core tape is sandwiched between the folded marginal tape edge portion and a major portion of one of the stringer tapes.
