Description

Es sind Reißverschlüsse vorgeschlagen worden, bei denen die Stoffkanten derartig gefaltet sind, daß die Schließglieder mit ihren. Kopfteilen in rillenartigen Falten liegen.Zippers have been proposed in which the fabric edges are folded in such a way that the locking members with their. Headboards in groove-like Wrinkles lie.

Diese rein theoretischen Vorschläge zeigten aber noch keine Möglichkeit zu einer rationellen Herstellung derartiger Reißverschlüsse.However, these purely theoretical proposals did not yet show any possibility for an efficient production of such zip fasteners.

Die Erfindung zeigt an Hand der vorliegenden Zeichnungen, wie .diese Reißverschlüsse besonders vorteilhaft hergestellt werden können. Beiden vorgeschlagenen Reißverschlüssen sind einzelne Glieder gezeigt. Im Gegensatz hierzu bestehen die Reißverschlußglieder gemäß der Erfindung vor dem Einfalten des Stoffes aus den in den Abb. i, 2, 3 und' q. gezeigten Profilstäben b und c. Diese Profilstäbe besitzen Trennfugen bi und cl. Der Profilstab b (Ab b. z und 2) hat, wie Abb. z zeigt, die Wulst b2. Diese dient zur festen Einsbindung des Stoffstreifens a, den man auf Abb. 5 sieht. Die Abb. 5 und 6 zeigen nun, wie beispielsweise .durch ein Rollenpaar d der im Querschnitt U-förmige Profilstab c um die Wulst b2 des Profilstabes b gepreßt wird. Dadurch erfolgt die feste Einbindung des Stoffes a. Nach diesem Vorgang werden dann die Glieder durch Hinundherbiegen an den Trennfugen bi und cl, die man beiden Abb. i, 2, 3 und q. sieht, gebrochen und damit voneinander getrennt. Mit,diesem vorstehend beschriebenen Ausführungsbeispiel ist an sich die Erfindung gekennzeichnet.The invention shows with reference to the present drawings how .these Zip fasteners can be produced particularly advantageously. Both proposed Zippers are shown individual links. In contrast, the Zipper members according to the invention before the folding of the fabric from the in Figs. i, 2, 3 and 'q. shown profile bars b and c. Own these profile bars Parting lines bi and cl. The profile bar b (Ab b. Z and 2) has, as Fig. Z shows, the Bead b2. This is used to firmly tie in the fabric strip a, which can be seen in Fig. 5 sees. Figs. 5 and 6 now show how, for example, through a pair of rollers d the cross-sectionally U-shaped profile rod c is pressed around the bead b2 of the profile rod b will. This results in the firm integration of the substance a. After this process will be Then the limbs by bending back and forth at the parting lines bi and cl, which you both Fig. I, 2, 3 and q. sees, broken and thus separated from each other. With this The embodiment described above is per se characterized the invention.

Das Einpressen des Stoffes kann aber auch durch schubartig wirkende mechanische Mittel erfolgen. Es ist ferner auch denkbar, daß die in den Abb. i, 2, 3 und q. gezeigten Profilstäbe aus nur einem Stab gebildet werden. Die Grundform wäre in diesem Falle zweckmäßig eine T-förmige, wie siedieAbb. 7 zeigt. Die Ansicht von A (Abb. 7) wäre :dieselbe wie bei Abb. z. Beim Einfalten und Einpressen des Stoffes werden die Schenkel 7, in derselben Weise U-förmig angepreßt, wie man bei Abb. 5 sieht.The pressing in of the substance can also be done in bursts mechanical means. It is also conceivable that the in Fig. I, 2, 3 and q. Shown profile bars are formed from only one rod. The basic form In this case, a T-shaped one, as shown in Fig. 7 shows. The view of A (Fig. 7) would be: the same as in Fig. z. When folding in and pressing in the Substance, the legs 7, pressed in the same way U-shaped, as in Fig. 5 sees.

Die Profilstäbe können auch aus Kunstharz, Polyvenylchlorid, Polyamid u. a. Kunststoffen hergestellt werden.The profile bars can also be made of synthetic resin, polyvinyl chloride, polyamide i.a. Plastics are made.
