Abstract: A tape stringer for a sliding clasp fastener having a web section and a woven filament section forming an end section of a tape. Both the web and the woven filament sections include a plurality of warp threads interwoven with a continuous weft thread and the woven filament section includes a spiral-shaped continuous plastic filament woven into the filament section. The spiral-shaped continuous plastic filament forms a row of connected together loops having coupling heads projecting beyond the end of the tape and having limbs that are inserted in and secured to the end section of the tape by the warp threads which engage the limbs along substantially their entire length.
