Abstract
A method of and an apparatus for manufacturing a woven stringer for a concealed type of slide fastener having a row of continuous filamentary coupling elements woven integrally into a stringer tape. The row of coupling elements are formed into a continuous helical coil structure which is woven into a longitudinal edge of the stringer tape as the latter is woven and which is oriented so that each of the coupling elements has its heel portion disposed to project transversely beyond the longitudinal edge of the stringer tape and its coupling head portion directed toward a web portion of the tape when the stringer is produced. The resulting stringer when in use is folded back on a longitudinal axis so that the coupling head projects beyond the tape edge but is concealed from view when a pair of such stringers are coupled together.
