Description

Verfahren zum Verbinden von Gegenständen durch Kunststoff und Vorrichtung zu seiner Ausführung Die Erfindung betrifft ein Verfahren und ein Gerät, mit welchem zwei oder mehrere flächenförmige Stoffe wie Textilien, Leder, Folien, Pappe durch Einpressen von Kunststoff nach Art einer Naht verbunden werden. Method for connecting objects by plastic and device for its implementation The invention relates to a method and a device with which two or more flat materials such as textiles, leather, foils, cardboard Injection of plastic can be connected in the manner of a seam.

Bisher wurden Textilien meist durch Nähen mittels Nähfäden aufeinander befestigt oder durch thermoplastischen Kunststoff in Form von Pulver oder Klebefolie verbunden. Zum maschinellen Nähen muß das Werkstück von beiden Seiten zugänglich sein. Beim Kleben werden nur die äußeren Fasern erfaßt. Auf größere Flächen angewandt ergibt sich bei Folienklebung eine Luftundurchlässigkeit, die bei Kleidungsstücken unerwünscht ist. Außerdem ist die Festigkeit von oberflächigen Klebeverbindungen beschränkt.So far, textiles have mostly been sewn onto one another using sewing threads attached or by thermoplastic in the form of powder or adhesive film tied together. For machine sewing, the workpiece must be accessible from both sides be. When gluing, only the outer fibers are gripped. Applied to larger areas With film gluing, air impermeability is the same as with garments is undesirable. In addition, the strength of surface adhesive bonds limited.

Eine gute Verbindung kann erreicht werden, wenn der Kunststoff tiefer in die einzelnen Stoffe eindringt bezw. sie durchdringt.A good connection can be achieved when the plastic is deeper penetrates respectively into the individual substances. penetrates them.

Dies wird erfindungsgemäß durch Einpressen von flüssigem Kunststoff als feinem Strahl durch die Stofflagen hindurch aus einer aufgesetzten Düse bewirkt. Unter Druck wird warmflüssiger Kunststoff in die porösen Stoffe eingepreßt und erstarren gelassen.According to the invention, this is achieved by injecting liquid plastic as a fine jet through the layers of fabric from an attached nozzle. Warm plastic is pressed into the porous material under pressure and solidifies calmly.

Eine solche Befestigung kann in aufeinanderfolgenden Punkten nahtförmig oder fortlaufend ausgeführt werden. Nach dem Erhärten des eingepreßten Kunststoffes sind die Textilien mittels einer Naht ähnlich einer Nietreihe aus durchgehendem Kunststoff dauerhaft miteinander verbunden. Das Erkalten und Erstarren der geringen eingespritzten Kunststoffmenge geht schnell vor sich.Such an attachment can be in the form of a seam in successive points or run continuously. After the pressed-in plastic has hardened are the textiles by means of a seam similar to a row of rivets made of continuous Plastic permanently bonded together. The cold and freezing of the minor injected amount of plastic goes on quickly.

Bei Verwendung von glasklarem Kunststoff wird die Verbindung nahezu unsichtbar.When using crystal clear plastic, the connection is almost invisible.

Die Vorrichtung besteht bei porösen Stoffen im wesentlichen aus einer gleichmäßig beheizten DUse, aus welcher ein feiner Strahl warmflilssigen Kunststoffs unter Druck ausgepreßt werden kann.The device consists essentially of a porous material evenly heated nozzle, from which a fine jet of warm-fluid plastic can be squeezed out under pressure.

In der DUe befindet sich ein nadelförmiger Kolben, der beim Abwärts gang in dem Ddsenkanal eine den Abmessungen entsprechende Kunststoffmenge aus der Düse herausdrückt. Darauf werden die Textilien eine kleine Strecke fortbewegt. Der Kolben geht nun aufwärts und der Düsenkanal füllt sich aus einer unter Druck stehenden Vorratskammer ganz oder teilweise mit Kunststoff.In the DUe there is a needle-shaped piston that, when going down gang in the Ddsenkanal an amount of plastic corresponding to the dimensions from the Presses out nozzle. The Textiles a little way moved. The piston now goes up and the nozzle channel fills out of one pressurized storage chamber wholly or partially with plastic.

Danach bewegt sich der Kolben von neuem abwärts. So entsteht eine Naht aus dünnen Kunststoffpfropfen, welche durch die Textilien voli hindurchgreifen. Zum Lösen der Naht braucht diese nur genügend erhitzt zu werden.Then the piston moves down again. This is how a Seam made of thin plastic plugs, which fully reach through the textiles. To loosen the seam, it only needs to be heated sufficiently.

Bei dichteren Stoffen, wie z. B. Leder, werden vorher Öffnungen zum leichteren Einspritzen des Kunststoffes angebracht. Dies kann durch eine Nadel oder einen Bohrer geschehen, der vor der Düse ebenso wie auf der Unterseite liegen kann.For denser fabrics, such as B. leather, openings for easier injection of the plastic attached. This can be done through a needle or a drill done, which can be in front of the nozzle as well as on the underside.

Die Figuren 1 - 3 zeigen die Verfahrensschritte in porösem Stoff, Fig. 4 - 6 die Verfahrensschritte in dichtem Stoff. Im einzelnen ist in Fig. 1 die heizbare Düse 1 mit der Vorratskammer 2 und dem Düsenkanal 3 dargestellt. Eine kolbenförmige Nadel 4 kann auf und nieder bewegt werden. Die mit flüssigem Kunststoff gefüllte Vorratskammer steht wenigstens zeitweise unter Überdruck.Figures 1 - 3 show the process steps in porous material, 4-6 show the process steps in dense fabric. In detail in Fig. 1 is the heatable nozzle 1 with the storage chamber 2 and the nozzle channel 3 shown. A flask-shaped Needle 4 can be moved up and down. The one filled with liquid plastic The storage chamber is at least temporarily under overpressure.

Die Düse ruht auf den beiden Stofflagen 5 und 6, die miteinander verbunden werden sollen. Der Düsenkanal ist durch die leicht angehobene Nadel verschlossen.The nozzle rests on the two layers of fabric 5 and 6, which are connected to one another should be. The nozzle channel is closed by the slightly raised needle.

In Fig. 2 ist die Nadel 4 stärker angehoben, sodaß sich der Düsenkanal aus der Vorratskammer füllen kann, worauf die Nadel niedergeht.In Fig. 2, the needle 4 is raised more so that the nozzle channel can fill from the storage chamber, whereupon the needle goes down.

Fig. 3 zeigt die Nadel nach dem Niedergehen. Aus dem Düsenkanal ist ein Kunststoffpfropfen ausgepreßt und in die Stofflagen eingedrungen. Bei dieser Nadelstellung werden die Stofflagen ein Stück fortbewegt, wonach sich der Vorgang wiederholt.Fig. 3 shows the needle after going down. From the nozzle channel is a plastic plug pressed out and penetrated into the layers of fabric. At this In the needle position, the layers of fabric are moved a little further, after which the process continues repeated.

Fig, 4 zeigt das Verbinden von zwei dichten Stoffen wie z. B.Fig, 4 shows the connection of two tight fabrics such. B.

Leder. Hier wird eine Öffnung fUr den Kunststoffpfropfen durch den Dorn oder Bohrer 7 von unten eingebracht. Der Dorn bewegt sich im Takt der Nadel.Leather. Here an opening is made for the plastic plug through the Mandrel or drill 7 introduced from below. The mandrel moves in time with the needle.

In Fig. 5 befinden sich Dorn und Nadel in ihrer höchsten Stellung, in Fig. 6 in ihrer untersten nachdem der Kunststoffpfropf ausgestoßen ist. Hiernach werden die Stofflagen um eine Stichentfernung weiterbewegt. Bei sehr kleinen Stichentfernungen ergibt sich eine fortlaufende Naht.In Fig. 5 the mandrel and needle are in their highest position, in Fig. 6 in their lowest after the plastic plug has been ejected. After that the layers of fabric by a stitch distance moved on. at very small stitch distances result in a continuous seam.
