ABSTRACT:
A fluid-tight slide fastener stringer has a fluid-tight tape chiefly made of rubber or synthetic resin on which tape a series of discrete coupling elements are supported along an inner longitudinal margin of the tape. The tape margin is folded so as to provide therealong a pair of spaced contact portions and a folded edge portion disposed between the contact portions. The tape has a foamed layer extending in and through at least the contact portions and the folded edge portion. At least the margin of the resultant tape is excellent in ability of restitution, causing an improved fluid-tightness between the opposed stringers.
