<p>In a woven slide fastener stringer (10) in which a gap-filling warp thread (20) extends under successive loops (14) of a coiled plastic filament (13) and alternately over and under picks of a foundation weft thread (16) so as to pull portions of the foundation weft thread (16) between the outermost upper binding warp thread (17a) and the next upper binding warp thread (17b) toward the lower side of the tape (11) substantially halfway between the upper and lower legs (14b), (14c) of the respective loops (14), at least one pair of space-retaining warp threads (23) is disposed between the outermost upper binding warp thread (17a) and the next upper binding warp thread (17b). The space-retaining warp threads (23) extend alternately over and under the upper and lower legs (14b), (14c) of the successive filament loops (14) so as to clamp the individual loops (14), thus keeping the latter in proper upright posture and free from staggering pitch.</p> |
