Verfahren zum Herstellen eines ReißverschlußbandesMethod of manufacturing a slide fastener tape

Die vorliegende Erfindung betrifft ein verfahren zum Herstellen eines Reißverschlußbandes mit Kuppelgliedern, die im Spritzgußverfahren an einem Tragband über Löchern in einem Randbereich desselben angebracht sind.The present invention relates to a method for Manufacture of a zip fastener tape with coupling elements that are injection-molded onto a fastener tape through holes are attached in an edge area of the same.

Reißverschlußbander der beschriebenen Art werden erzeugt, indem ein Tragband mit Löchern versehen wird, woraufhin Kuppelglieder über den Löchern an das Tragband angespritzt werden. Diese Löcher wurden mit einem Stanzstempel oder einer spitzen Nadel erzeugt, was jedoch nachteilhaft ist, weil die gestanzten Löcher zu einer Vergrößerung neigen und ein Ausfransen der Fasern des Tragbandes verursachen, wenn das Tragband gespannt wird, und die von der Nadel auseinandergedrückten Fasern des Tragbandes kehren gerne raschZipper tapes of the type described are produced by providing a fastener tape with holes, whereupon Coupling elements are molded onto the fastener tape over the holes. These holes were made with a punch or a pointed needle, which is disadvantageous because the punched holes tend to enlarge and cause the fibers of the fastener tape to fray when the fastener tape is stretched, and those that are pushed apart by the needle Fibers of the carrier tape like to sweep quickly

in ihre Ausgangslage zurück und die Löcher schließen sich im ungünstigsten Fall wieder.back to their original position and the holes close again in the worst case.

In dem am 26. Mai 1936 veröffentlichten US-Patent 2 041 848 und in dem am 21. Februar 1956 veröffentlichten US-Patent 2 735 139 sind Lösungsvorschläge für diese Probleme beschrieben. Gemäß dem erstgenannten Patent werden außerhalb der Gießformen Löcher in das Tragband gestochen, und die Kuppelglieder werden in den Gießformen einzeln über dem Loch angespritzt. Eine solche Anordnung hat demzufolge eine sehr geringe Lexstungsfähigkeit. Gemäß dem letztgenannten Patent wird eine Nadel durch das Band in den Gießformen hindurchgestochen und sodann zurückgezogen, wenn sich das Loch beim Spritzgießen mit geschmolzenem Material gefüllt hat. Die beschriebenen Gießformen sind wegen der erforderlichen Abstimmung der Bewegung zwischen den Gießformen und der Nadel verhältnismäßig kompliziert aufgebaut. Eine gemeinsame Schwierigkeit dieser älteren Patente besteht darin, daß die aufeinanderfolgende Ausbildung einzelner Löcher zu einer ungleichmäßigen Größe und Teilung der Löcher führen kann.U.S. Patent 2,041,848 issued May 26, 1936 and U.S. Patent No. 2,041,848 issued February 21, 1956 US Pat. No. 2,735,139 describes proposed solutions to these problems. According to the first-mentioned patent Holes are punched in the fastener tape outside of the molds, and the coupling elements are individually over in the molds injected into the hole. Such an arrangement therefore has very poor performance. According to the latter Patent, a needle is stuck through the tape in the molds and then withdrawn when the Filled hole with molten material during injection molding. The casting molds described are required because of the Adjustment of the movement between the molds and the needle is relatively complicated. A common Difficulty with these prior patents is that the successive formation of individual holes into one uneven size and pitch of the holes.

Der Erfindung liegt die Aufgabe zugrunde, ein verfahren zum Herstellen eines Rexßverschlußbandes zu schaffen, das mit einer Reihe von gleichabständigen Löchern versehen ist, an denen eine Reihe von Kuppelgliedern angeordnet ist. Diese Löcher sollen dabei dimensionsstabil sein und fixierte Ränder haben, die ein Ausfransen der Fasern oder Fäden des Tragbandes verhindern. Mit dem erfindungsgemäßen verfahren soll sich ein Reißverschlußband fortlaufend mit großer Geschwindigkeit herstellen lassen.The invention is based on the object of a method to create a zip fastener tape which is provided with a series of equally spaced holes, on which a number of coupling elements are arranged. These holes should be dimensionally stable and have fixed edges that prevent the fibers or threads of the tape from fraying. With the method according to the invention is intended a zipper tape can be continuously produced at high speed.

Gemäß der Erfindung wird ein aus Kunstfasern bestehendes oder Kunstfasern enthaltendes Tragband entlang einem Randbereich desselben zwischen einem Ultraschall-Schwingkörper undAccording to the invention, a support tape made of synthetic fibers or containing synthetic fibers is positioned along an edge region the same between an ultrasonic vibrating body and

einer Reihe von Zähnen angeordnet, die einen kreisförmigen Amboß umgeben, gegen den der Schwingkörper gepreßt wird, um Bereiche des Tragbandes in gleichförmigen Intervallen fortlaufend zu schmelzen, wenn der Amboß rotiert, wodurch in dem Randbereich des Tragbandes eine Reihe von Löchern gebildet wird. Das Tragband wird sodann auf den Zähnen gekühlt, wenn es sich von dem Schwingkörper wegbewegt, und es wird von den Zähnen abgestreift, damit es zwischen zwei zusammenwirkende Gießformen eingeleitet wird, die gleichzeitig eine Reihe von Kuppelgliedern an das Tragband bzw. über die in dem Tragband angeordneten Löcher anspritzen.a series of teeth surrounding a circular anvil against which the vibrating body is pressed to Continuously melt areas of the fastener tape at uniform intervals as the anvil rotates, thereby causing the Edge area of the tape a series of holes is formed. The fastener is then cooled on the teeth when it moves away from the vibrating body, and it is stripped from the teeth so that it is between two cooperating Casting molds are initiated, which simultaneously have a number of coupling elements on the fastener tape or on the in the fastener tape the arranged holes.

Wie dies in Fig. 1 gezeigt ist, wird ein fortlaufendes, im wesentlichen endloses Tragband 10 aus Kunstfasern oderAs shown in Fig. 1, a continuous, substantially endless support tape 10 made of synthetic fibers or

Kunstfasern enthaltenden Mischfasern, das einen verstärkten Ra»d 11 aufweist, zunächst entlang einem dem verstärkten Rand 11 benachbarten Längsrand mit einer Reihe von Löchern 12 versehen, wobei die Löcher 12 mit einer Teilung P unter gleichmäßigen Abständen angeordnet sind. Eine Reihe von Kuppelgliedern 13 aus Kunstharz wird um den verstärkten Rand herum und über den Löchern 12 im Spritzgußverfahren angebracht. Wie dies am besten aus Fig. 2 ersichtlich ist, hat jedes Kuppelglied 13 auf jeder Seite des Tragbandes 10 einen Schenkel 13a bzw. 13b, die durch eine integrierte Brücke 15 miteinander verbunden sind, die sich durch eines der Löcher 15 erstreckt, wobei dip Brücke 15 aus der Masse eines geschmolzenen Materials gebildet ist, das beim Spritzgießen in das Loch 12 hineinfließt. Da sich die Brücken 15 quer durch das Tragband 10 hindurch erstrecken, sind die Kuppelglieder 11 luf dem Tragband 10 in ihrer Lage zuverlässig verankert. Auf diese Weise wird ein Reißverschlußband 14 gebildet.Mixed fibers containing synthetic fibers, which has a reinforced radius 11, initially along one of the reinforced fibers Edge 11 adjacent longitudinal edge provided with a series of holes 12, the holes 12 with a pitch P below are evenly spaced. A series of synthetic resin fastener elements 13 are placed around the reinforced rim around and over the holes 12 by injection molding. As can best be seen from Fig. 2, has each coupling element 13 on each side of the fastener tape 10 has a leg 13a or 13b, which is connected by an integrated bridge 15 are connected to each other, which extends through one of the holes 15, wherein dip bridge 15 from the mass of a molten Material is formed that flows into the hole 12 during injection molding. Since the bridges 15 transversely extend through the fastener tape 10, the coupling elements 11 are reliable in their position on the fastener tape 10 anchored. In this way, a slide fastener tape 14 is formed.

Fig. 3 zeigt eine Vorrichtung 16 zur Ausführung eines Verfahrens zum Herstellen eines solchen Reißverschlußbandes 14. Die Vorrichtung 16 hat an einem Ende eine obere und eine untere Zuführrolle 17 und 18 zum Zuführen des Tragbandes 10, das sodann mittels einer Spannrolle 19 in geeignetem Maße gespannt wird, bevor es von einer Führung 20 auf einem Untergestell 21 einer Einrichtung 22 zur Ausbildung der Löcher 12 zugeführt wird.Fig. 3 shows a device 16 for performing a A method of making such a slide fastener tape 14. The device 16 has a top and a top at one end lower feed rollers 17 and 18 for feeding the carrier tape 10, which is then tensioned to a suitable extent by means of a tensioning roller 19 before it is guided by a guide 20 on an underframe 21 of a device 22 for forming the holes 12 is fed.

Die Einrichtung 22 besteht aus einem Ultrascball-Schwingkörper 23, der durch eine im Untergestell 21 angeordnete Öffnung 24 hindurch nach oben ragt, und aus einem kreisförmigen Amboß 25, der mit einer Welle 26 in einem auf dem Untergestell 21 angeordneten Bügel 28 drehbar gelagert ist, wobei die Welle 26 von einem (nicht gezeigten) Motor angetriebenThe device 22 consists of an ultrascball oscillating body 23, which protrudes upward through an opening 24 arranged in the underframe 21, and a circular one Anvil 25 which is rotatably mounted with a shaft 26 in a bracket 28 arranged on the underframe 21, wherein the shaft 26 is driven by a motor (not shown)

wird. Der Schwingkörper 23 kann von bekannter Konstruktion sein, wie sie beim Ultraschallschweißen verwendet wird. Der kreisförmige Amboß 25 ist an seinem Umfang mit einer Reihe von Zähnen oder Vorsprüngen 29 versehen, die radial nach aussen abstehen, wobei die Zähne 29 in Umfangsrichtung mit der Teilung P im gegenseitigen Abstand voneinander angeordnet sind. Die Zähne 29 ragen rechtwinklig gegen den Schwingkörper 23, wenn der Amboß 29 rotiert. Wenn sich das Tragband 10 in Richtung des Pfeils 30 vorwärtsbewegt, dann wird es zwischen dem in Ultraschallschwxngungen versetzten Schwingkörper 23 und den Zähnen 29 eingeklemmt, wenn diese bei der Verdrehung des Ambosses 25 in Richtung des Pfeils 31 mit dem Schwingkörper 23 in Berührung gebracht werden. Wenn das Tragband 10 zwischen dem Schwingkörper 23 und dem Amboß 25 hindurchbewegt wird, dann werden die Zähne 29 gegen den Schwingkörper 23 in das Tragband 10 hineingedrückt, wobei die mit den Zähnen 29 fluchtenden Bereiche des Tragbandes infolge der von dem Ultraschall-Schwingkörper 23 erzeugten Hitze weggeschmolzen werden. Die Ränder der auf diese Weise gebildeten Löcher 12 sind daher geschmolzen und fixiert, während das Tragband 10 von dem Amboß 25, dessen Zähne 29 in die Löcher 11 eingreifen, in einer bogenförmigen Bahn von dem Schwingkörper 23 wegbewegt wird, wobei das Tragband in diesem Umfangsbereich 32 zwangsläufig oder durch natürliche Luftströmung gekühlt wird.will. The vibrating body 23 can be of a known construction, such as is used in ultrasonic welding. Of the circular anvil 25 is provided on its circumference with a series of teeth or projections 29 which radially outward protrude, the teeth 29 arranged in the circumferential direction with the pitch P at a mutual distance from one another are. The teeth 29 protrude at right angles against the oscillating body 23 when the anvil 29 rotates. When the tape 10 moved forward in the direction of arrow 30, then it is between the vibrating body displaced in ultrasonic vibrations 23 and the teeth 29 are clamped when they are jammed when the anvil 25 is rotated in the direction of the arrow 31 with the oscillating body 23 are brought into contact. When the fastener tape 10 moves through between the oscillating body 23 and the anvil 25 is, then the teeth 29 are pressed against the oscillating body 23 in the carrier tape 10, with the teeth 29 aligned areas of the carrier tape as a result of the ultrasonic vibrating body 23 generated heat are melted away. The edges of the holes 12 formed in this way are therefore melted and fixed, while the fastener tape 10 from the anvil 25, the teeth 29 of which engage in the holes 11, in an arcuate path is moved away from the oscillating body 23, the carrier tape in this circumferential region 32 inevitably or cooled by natural air currents.

Demzufolge fransen die Löcher 12 nicht aus, und sieAs a result, the holes 12 do not fray, and they do

aind dimensionsstabiler als wenn sie durch Ausstanzen oderaind more dimensionally stable than if they were punched out or

Auseinanderspreizen der Fasern des Tragbandes 10 gebildet wären.Spreading apart of the fibers of the carrier tape 10 would be formed.

Ein Abstreifer 33 ist an dem Bügel 28 angeordnet und h*t ein spitzes Ende 27, das nahe dem Umfang des Ambosses 25 und näherungsweise diametral gegenüberliegend zu demA scraper 33 is arranged on the bracket 28 and has a pointed end 27 which is close to the circumference of the anvil 25 and approximately diametrically opposite to that

Schwingkörper 23 angeordnet ist. Der Abstreifer 33 hat eine Düse 34 um Luft 35 mit Raumtemperatur gegen den Amboß 25 zu blasen, um diesen zu kühlen. Das Tragband 10, das an den Löchern 12 an den Zähnen 29 anhaftet, wird durch den Abstreifer 33 zuverlässig abgelöst und um eine Umlenkrolle 36 herumgeführt, die auf einer Welle 37 drehbar gelagert ist, die in einem auf dem Untergestell 21 angeordneten Support 38 angeordnet ist.Vibrating body 23 is arranged. The scraper 33 has a nozzle 34 to direct air 35 at room temperature against the anvil 25 blow to cool it. The fastener tape 10 adhered to the holes 12 on the teeth 29 is removed by the scraper 33 reliably detached and guided around a deflection roller 36 which is rotatably mounted on a shaft 37 which is shown in FIG a support 38 arranged on the underframe 21 is arranged.

Wie dies in Fig. 3 gezeigt ist, wird das Tragband 10 mit den darin ausgebildeten Löchern 12 durch ein Teilungsmeßgerät 40 hindurchbewegt und sodann von einer oberen und einer unteren Vorschubwalze 41, 42 vorwärts bewegt, um es in einem geeigneten (nicht gezeigten) Behälter zu speichern. Das Tragband 10 wird dann von dem Behälter abgezogen, so daß es in eine Spritzgießmaschine 43 schrittweise eingeführt wird. Dieses Speichern und Abziehen ist notwendig, weil das Spritzgießen an dem Tragband 10 intermittierend durchgeführt wirdr wie dies nachfolgend beschrieben wird. Die Spritzgießmaschine 43 hat eine obere und eine untere Form 44 und 45, die miteinander zusammenwirken, um eine Einheitslänge des Tragbandes 10 zwischen sich einzuklemmen und jeweils eine Anzahl Kuppelglieder 13 in Deckung mit den Löchern 12 an das Tragband 10 anzuspritzen, wodurch eine Einheitslänge eines Reißverschlußbandes 14 erzeugt wird. Die Spritzgießmaschine 43 kann beim schrittweisen Zuführen des Tragbandes 10 zu der Gießform wiederholt betätigt werden, je nachdem wieviele aufeinanderfolgende Reihen von Kuppelgliedern 13 gewünscht werden, so daß jede gewünschte Länge des Reißverschlußbandes 14 entsprechend einem Vielfachen der Einheitslänge erzeugt werden kann. Das auf diese Weise erzeugte Reißverschlußband wird von zwei Abziehrollen 46, 47 zum Speichern abgezogen.As shown in Fig. 3, the fastener tape 10 with the holes 12 formed therein is passed through a pitch meter 40 and then advanced by upper and lower feed rollers 41, 42 to be placed in a suitable container (not shown) to save. The fastener tape 10 is then peeled off the container so that it is gradually fed into an injection molding machine 43. This storing and drawing off is necessary because the injection molding is performed intermittently to the fastener tape 10 r as will be described below. The injection molding machine 43 has an upper and a lower mold 44 and 45, which cooperate with each other to clamp a unit length of the fastener tape 10 between them and in each case a number of coupling elements 13 in registration with the holes 12 on the fastener tape 10, whereby a unit length of a slide fastener tape 14 is generated. The injection molding machine 43 can be operated repeatedly in stepwise feeding of the fastener tape 10 to the mold, depending on how many successive rows of coupling elements 13 are desired, so that any desired length of the slide fastener tape 14 corresponding to a multiple of the unit length can be produced. The zip fastener tape produced in this way is peeled off by two peeling rollers 46, 47 for storage.
