daß die beheizte Preßbacke eine bestimmte Temperatur nicht überschreitet· Da es jedoch Folien aus verschiedenen Materialien sowie auch Haterialdicken gibt, dauert das Zusammenschweißen von dicken Folien bein bekannten Gerät auf Grund der Anordnung des Wärmeregiere in der beheizten Preßbacke verhältnismäßig lange, weil bei diesem Gerät vom Temperaturfühler die Tenperatur an Heizelement, nicht aber die Temperatur im Verschweißungsbereich der Folien erfaßt wird·that the heated press jaw does not have a certain temperature exceeds · However, since there are foils made of different materials as well as material thicknesses, the welding together takes time of thick foils leg known device due to the arrangement of the heat regulator in the heated press jaw for a relatively long time, because in this device from the temperature sensor the temperature of the heating element, but not the temperature in the welding area of the foils

Der Neuerung liegt nun die Aufgabe zugrunde, ein Gerät zum Verschweißen von Folien so auszubilden, daß ein genauesEErfassen der VerschweiBungstenperatur sowie ein rechtzeitiges und sicheres Beendigen des Schweißvorganges sicher gestellt ist·The innovation is now based on the task of designing a device for welding foils in such a way that an accurate detection the welding temperature as well as a timely and safe termination of the welding process is ensured

Die gestellte Aufgabe wird neuerungsgenäB dadurch gelöst, daß der Temperaturfühler des Wärmereglers in der unbeheizten Schiene angeordnet ist.The task at hand is solved by the innovation, that the temperature sensor of the heat regulator is arranged in the unheated rail.

Durch die Heuerung wird erreicht, daß die zu verschweißenden Folien zwischen den Temperaturfühler des Wärmereglers und den Heizelement zu liegen kommen· Daraus ergibt sich nun der Vorteil, daß die Beendigung des Sehweißvorganges unabhängig von der Dicke und vom Material der zu verschweissenden Folien vom Temperaturfühler -siir genau erfaßt werden kann·By hiring it is achieved that the to be welded Foils come to lie between the temperature sensor of the heat regulator and the heating element · This results now the advantage that the end of the welding process is independent of the thickness and the material to be welded Foils can be detected precisely by the temperature sensor can·
