Abstract
A fluid-tight slide fastener comprises a pair of slide fastener halves each including a support tape, a row of continuous coupling elements extending longitudinally along the inner edge of the tape on one side thereof, and an elastomeric sealing member overlying the other side of the tape. The tape has a longitudinal ridge substantially defining the inner edge and supporting the row of coupling elements laterally longitudinally by means of stitching threads. A portion of the threads is disposed adjacent to the ridge to prevent the latter from moving remotely from the coupling elements row for thereby supporting the ridge intimately enough to ensure the abuttment of opposed sealing edges of the tapes when the fastener halves are coupled together.
