A multiplicity of knitting needles and one or more knitting needles are slid vertically along first and second needle beds, respectively, which are disposed in a back-to-back relationship with and spaced a predetermined distance from each other. The second needle bed extends along only one end portion of the first needle bed. And at the same time, a predetermined number of knitting yarn guides are swung and shogged. During that time, a monofilament bending means disposed near one end of the first needle bed reciprocates along the upper space between the first and second needle beds at an underlapping position to continuously form individual fastener elements by bending the monofilament and to knit the formed fastener elements successively in a warp-knit fastener tape by the back-to-back needles in the first and second needle beds simultaneously with the knitting of the tape.

Plusieurs aiguilles de tricotage et au moins une aiguille de tricotage sont insérées verticalement sur des première et deuxième fontures, respectivement, qui sont placées dos à dos et à une distance préétablie. La deuxième fonture se prolonge seulement à une extrémité de la première fonture. En même temps, un nombre préétabli de guide-fil sont balancés et chevalés. Durant ce temps, un dispositif pour courber le monofilament placé près d'une extrémité de la première fonture a un mouvement alternatif le long de l'espace supérieur entre la première et la deuxième fontures à une position de jetée-sous pour former en continu des éléments de fermeture individuels en courbant le monofilament, et pour tricoter les éléments de fermeture formés successivement en un ruban de dispositif de fermeture à maille jetée au moyen des aiguilles dos à dos de la première et deuxième fontures simultanément avec le tricotage du ruban.
