Abstract

Thermoplastics strands or filamentary elements are ultrasonically bonded to synthetic fibrous inking ribbons using a sonotrode which pierces the synthetic fabric and drags the so-loosened fibre ends with it into a massive plastics part where they are sealingly anchored. Simple, inexpensive and firm bonding of the typewriter ribbon end to a direction reversing plastics component may be achieved without application of potentially damaging heat welding.

Befestigung von eie mittels UltraschallFixing of eggs by means of ultrasound

Die Erfindung betrifft die Verbindung von Kunststoffgeweben mit massiven thermoplastischen Kunststoffteilen, insbesondere Umschaltelemente und Spulen an Farbbändern.The invention relates to the connection of plastic fabrics with solid thermoplastic plastic parts, in particular Switching elements and spools on ribbons.

Während man bisher schon massive thermoplastische Kunststoffteile, z. B. Drähte aus Polyamiden mit Hilfe von Wärm6 mit Naturfasergeweben verbinden konnte und auf diese Weise eine innige, haltbare, einfache und billige Verbindung der beiden Teile bewirkte, machte es Schwierigkeiten, das gleiche Prinzip auch auf die Verbindung von thermoplastischen Kunststoffteilen mit Geweben aus Kunstharzfasern anzuwenden. Unter der Einwirkung der erforderlichen Wärme schmolz ja nicht nur das Kunststoffteil, sondern gleichermaßen auch das Kunstharzfasergewebe, bei dem es sich üblicherweise um ein sehr feines und dünnes Gewebe handelt.While massive thermoplastic plastic parts, z. B. could connect wires made of polyamides with natural fiber fabrics with the help of heat6 and in this way caused an intimate, durable, simple and cheap connection between the two parts, it made it difficult The same principle can also be applied to the connection of thermoplastic plastic parts with fabrics made of synthetic resin fibers. Under the influence of the required heat, not only did the plastic part melt, but also melted also the synthetic resin fiber fabric, which is usually a very fine and thin fabric.

Hier hat man jetzt einen Ausweg gefunden, mit dessen Hilfe man eine derartige Verbindung zwischen massiven Teilen aus thermoplastischen Kunststoffen und Geweben aus Kunstharzfasern herstellen kann, ohne Wärme anwenden zu müssen. Man bedient sich der Hilfe des Ultraschalls.Here one has now found a way out, with the help of which such a connection between massive parts can be made Can produce thermoplastic plastics and fabrics from synthetic resin fibers without having to apply heat. One serves take the help of ultrasound.

Das erfindungsgemäße Verfahren besteht darin, daß eine Sonotrode das Kunstharzfasergewebe durchstößt und die dabei freigewordenen Faserenden mit in den massiven Kunststoff hineinnimmt und dort verschweißend verankert.The inventive method consists in that a sonotrode the synthetic resin fiber fabric pierces and the thereby become free Takes fiber ends into the solid plastic and anchored there by welding.

Vorzugsweise wird Durchtrennung und anschließende Verschweißung abschnittsweise aber gleichmäßig über die ganze Breite des Gewebes verteilt durchgeführt.Preferably, the severing and subsequent welding is carried out in sections but evenly over the carried out across the entire width of the fabric.

Nach dem vorliegenden Verfahren lassen sich vornehmlich und vorteilhaft Verbindungen zwischen Umschaltelementen und Farbbändern einerseits und Bandspulen aus Kunststoffen mit Farbbändern andererseits herstellen. Voraussetzung ist selbstverständlich, daß sowohl das Bandgewebe aus thermoplastischem Kunstharzfasermaterial besteht als auch daß die genannten Elemente aus thermoplastischem Kunstharz erstellt worden sind.According to the present method, connections between switching elements can be primarily and advantageously and produce ribbons on the one hand and plastic tape reels with ribbons on the other. Requirement is it goes without saying that both the woven fabric is made of thermoplastic synthetic resin fiber material and that the elements mentioned have been created from thermoplastic synthetic resin.

Die beigefügten schematischen Darstellungen sollen die Erfindung näher erläutern:The attached schematic representations are intended to explain the invention in more detail:

Die Figur 1 zeigt im Schnitt einen massiven drahtförmigen Kunststoffteil aus thermoplastischem Material (1), ein darauf aufgelegtes Gewebe aus thermoplastischem Material (2) und einer Sonotrode (3). Unter Einwirkung des Ultraschalles dringt nun die Sonotrode (3) durch das Gewebe (2) hindurch in den Kunststoffkörper (1) hinein und nimmt dabei mit ihrer Spitze die freigewordenen Enden (4a) und (4b) des Gewebes (2) mit, um sie dort verschweißend zu verankern.Figure 1 shows in section a solid wire-shaped Plastic part made of thermoplastic material (1), a fabric made of thermoplastic material (2) placed on it and a sonotrode (3). Under the action of the ultrasound, the sonotrode (3) now penetrates through the tissue (2) into the plastic body (1) and takes it with her Tip the exposed ends (4a) and (4b) of the fabric (2) in order to anchor them there by welding.

In Figur 2 ist dargestellt, wie sich die vorliegende Erfindung an einem Farbband ausnimmt, wobei übereinander angeordnet die Seitenansicht und die Draufsicht dargestellt worden ist. Mit dem Farbband (6) aus thermoplastischem Kunststoffgewebe sind zunächst die beiden Umschaltelemente (7a) und (7b) nach der Art der Figur 1 verbunden, und außerdem sind beide Bandenden mit Spulenkernen (5a) und (5b) aus thermoplastischem Kunststoffmaterial in gleicher Weise verbunden worden. Die Draufsicht in Figur 2 (unterer Teil) zeigt, daß die Verbindungsstellen (9), (lO) und (11) jeweils äbschnittsförmig angeordnet und über die ganze Bandbreite verteilt worden sind, wobei die Größe und Form derFIG. 2 shows how the present invention works on an ink ribbon, being arranged one above the other the side view and the top view has been shown. With the ribbon (6) made of thermoplastic synthetic fabric the two switching elements (7a) and (7b) are first connected in the manner of FIG. 1, and also Both ends of the tape are connected in the same way with spool cores (5a) and (5b) made of thermoplastic material been. The top view in Figure 2 (lower part) shows that the connection points (9), (10) and (11) respectively Arranged in sections and across the entire bandwidth have been distributed, the size and shape of the

Abschnitte unterschiedlich gehalten sein kann.Sections can be kept different.
