Titeltitle

Die Erfindung "betrifft eine Glühband-Schweißmasehine, die für die Verschweißung von thermoplastischen Folien und Folienschläuchen in Betracht kommt.The invention "relates to an incandescent strip welding machine, which is suitable for welding thermoplastic films and film tubes.

Die erfindungsgemässe Schweißmaschine arbeitet in der Weise, daß die zu verschweißenden Folien aufeinandergelegt und durch die zwei Klemmleistenpaare festgehalten werden. Durch Betätigen des Fußhebels werden dann die Folien durch das mittlere Klemmleistenpaar festgeklemmt. Im gleichen Arbeitsgang folgt dann durch direkte Einwirkung eines elektrisch erwärmten Glühdrahtes die Abschmelzung bzw. das Auseinandertrennen der Folien. Infolge der Oberflächenspannung ziehen sich die abgeschnittenen Kanten in Sichtung Klemmleisten zurück. Durch die untere, zwischen den Klemmleisten liegende Federleiste werden dann die Schweißnähten nach oben gedrückt. Die Abkühlung erfolgt an der Luft sehr rasch.The welding machine according to the invention works in the Way that the foils to be welded are placed on top of one another and held in place by the two pairs of clamping strips will. By operating the foot lever, the foils are then pushed through the middle pair of clamping strips clamped. Then follow in the same process direct action of an electrically heated filament, the melting or the separation of the slides. As a result of the surface tension, the cut edges pull towards the terminal strips return. The weld seams are then made through the lower spring strip located between the terminal strips pushed up. The cooling takes place very quickly in the air.

Die Zeichnung zeigt in Fig. I die Schweißvorrichtung und zwar sind a und b die Klemmleistenpaare, die die Folien festhalten. Das Klemmleistenpaar a wird mittels Fußhebels, nachdem die Folien eingelegt sind, gegen das Leistenpaar b gedrückt, c ist die Federleiste, die durch das Glühband d beim Schweißvorgang nach unten gedruckt wird. Durch die Federkraft wird die Federleiste c nach oben gegen das Klemmleistenpaar a gedruckt. Fig. II zeigt Federleiste c und das Klemmleistenpaar b.The drawing shows in Fig. I the welding device, namely a and b are the pairs of terminal strips that the Hold on to foils. The pair of terminal strips a is countered by means of a foot lever after the foils have been inserted the pair of bars b is pressed, c is the spring bar, which is pushed down by the glow strip d during the welding process is printed. The spring force presses the spring strip c upwards against the pair of clamping strips a. Fig. II shows spring strip c and the pair of clamping strips b.

Das Gerät weist noch gegenüber den anderen Geräten den Vorteil auf, daß in einem Arbeitsgang zwei Beutel abgeschnitten und gleichzweitig geschweißt werden, wogegen bei lärmeimpuls die Beutel auf einer anderen Maschine erst auf Maß geschnitten und dann geschweißt werden müssen.The device has the advantage over the other devices that two bags in one operation cut off and welded at the same time, whereas with a noise impulse the bags are placed on another Machine must first be cut to size and then welded.

Diese Vorrichtung liefert eine gute Verbindung, die vor allem keinerlei Kerbwirkung zeigt.This device provides a good connection which, above all, shows no notch effect.
