The present invention relates to an improvement of the method for producing a zipper and the zipper described in patent 92 375 (the main patent).
Glidelåsen i henhold til hovedpatentet The zipper according to the main patent
er av den art, hvis kobleelementer (glidelåselementer) som er festet til et bånd, ut-gjøres av en fortløpende tråd eller av et tråd- eller bånd-formet legeme av kunststoff, og i henhold til fremgangsmåten ifølge hovedpatentet bøyes tråden fortlø-pende til stort sett meanderform; vendestedene på begge sider festes til et av et bånd eller en vulst bestående underlag, idet de mellom vende- eller ombøynings-stedene rettlinjet forløpende, sprosseformede partier bøyes til U-form langs meanderens plan ved at vendestedene føres mot hinannen før eller etter at de er festet til underlagene; de partier som befinner seg mellom vendestedene før eller etter om-bøyningen omformes til låselementer. is of the kind whose connecting elements (zipper elements) which are attached to a band consist of a continuous thread or of a thread- or band-shaped body made of plastic, and according to the method according to the main patent, the thread is continuously bent to mostly meander form; the turning points on both sides are attached to a substrate consisting of a band or a bead, the slat-shaped sections running in a straight line between the turning or bending points are bent into a U-shape along the plane of the meander by bringing the turning points towards each other before or after they are attached to the substrates; the parts located between the turning points before or after the re-bending are transformed into locking elements.
Glidelåsen kan ennvidere i henhold The zipper can extend accordingly
til hovedpatentet være fremstilt av en flat-profilert tråd. Båndet som tjener til å feste vendestedene på den ene side av meandertråden, ligger hensiktsmessig helt inntil midten av de sprosseformede, tverr-gående partier av tråden. to the main patent be made of a flat-profiled wire. The tape which serves to fasten the turning points on one side of the meander wire is conveniently right up to the middle of the bar-shaped, transverse parts of the wire.
Forbedringen av fremgangsmåten i The improvement of the procedure i
henhold til hovedpatentet består i at de mot hinannen førte eller bøyde vendesteder av meanderen sveises til et av et bånd eller en vulst bestående underlag (holdestrimmel) av kunststoff, eller i at meanderens vendesteder utvides og/eller bøyes according to the main patent consists in the fact that the opposite or bent turning points of the meander are welded to a substrate consisting of a band or a bead (holding strip) made of plastic, or in that the turning points of the meander are widened and/or bent
ut i sideretningen for å tjene som førin-ger for skyverleppene. Ennvidere ligger der på glidelåsrekkens vendesteder en dekkstrimmel som er klebet eller sveiset til glidelåsrekkens ben og/eller til det mellom benene liggende bærebånd. out laterally to serve as guides for the pusher lips. Furthermore, there is a cover strip at the turning points of the zip line which is glued or welded to the legs of the zip line and/or to the carrying strap lying between the legs.
Oppfinnelsen skal forklares nærmere under henvisning til tegningene, hvor fig. The invention will be explained in more detail with reference to the drawings, where fig.

I henhold til utførelseseksemplet på fig. 1 og 2 er der til en meanderformet kunststoff tråds 1 vendesteder 11 sveiset en holdestrimmel 3 av kunststoff, fortrinnsvis med rundt tverrsnitt. I stedet for en rund tråd kan der også anvendes en kunststofftråd med et hvilket som helst annet pro-fil. Som fig. 2 viser, ligger holdestrimlen 3 an mot vendestedene. Av figurene ses ennvidere at der på de steder 11' av kunst-stofftråden som vender fra vendestedene 11, er utformet fremspring 12 som f. eks. er oppstått ved stuking. Ved en ferdig lås griper disse fremspring i hinannen. According to the embodiment in fig. 1 and 2, a retaining strip 3 of plastic, preferably with a round cross-section, is welded to the turning points 11 of a meander-shaped plastic wire 1. Instead of a round wire, a plastic wire with any other profile can also be used. As fig. 2 shows, the retaining strip 3 rests against the turning points. From the figures, it can also be seen that at the places 11' of the plastic thread facing away from the turning points 11, protrusions 12 have been formed, such as is caused by sprains. In the case of a finished lock, these protrusions grip each other.
Ifølge fig. 3 er den til meandertrådens vendesteder sveisede kunststoff-holdestrim- According to fig. 3 is the plastic holding strip welded to the turning points of the meander wire

Fig. 9 further shows that the rectangular cross-section of the turning points has its longest axis oriented perpendicular to the plane of the belt and its shortest axis oriented parallel to the plane of the belt, and correspondingly in the case of an elliptical cross-section.
