Die bekannten blaschinen und Vorrichtungen dieser Art sind meist sehr umständlich oder unzureichend für eine billige und haltbare Heißverklebung.The known blow machines and devices of this type are usually very awkward or insufficient for a cheap and durable heat seal.

Zweck der Erfindung ist die Beseitigung dieser Mängel und die Schaffung einer Maschine, auf welcher ein betriebssicheres selbsttätiges Heißverklel>en der Werkstücke, wie insbesondere Beutel, sichergestellt ist. Erreicht wird dies dadurch, daß an einer Maschine der vorgenannten Art die Klemmbacken, von denen die eine an dem beweglichen Träger fest und die andere dazu beweglich, wie z. B. schwenkbar, angeordnet ist, zangenartig ausgebildet sind. Dabei sind für die bewegliche Klemmbacke Mittel zu ihrer nachgiebigen Anpressung gegen die feste Klemmbacke und Mittel zu ihrer vorübergehenden Abhebung von der festen Klemmbacke am Beginn und am Ende des Förderweges für die einzelnen Werkstücke vorgesehen. Vor der Stelle der Bewegungsbahn der Klemmbacken, an welcher das durch Heizung und Pressung an den Verbindungsnähten verklebte Werkstück durch öffnung der Klemmbacken freigegeben wird, ist eine in Abhängigkeit von der Förderbewegung der Klemmbacken gesteuerte Festhaltevorrichtung für das Werkstück vorgesehen. Die Zubringereinrichtung für die Werkstücke, die Mittel zum vorübergehenden Öffnen der beheizten Klemmbacken sowie die Antriebsmittel für den Klemmbackenträger und die Festhaltevorrichtung sind so in Zusammenwirkung gebracht, daß die Werkstücke selbsttätig in fortlaufendem Arbeitsgang heißverklebt werden. Bei Verwendung von an ihren Ireßflächen geriffelten Klemmbacken sind die Riffelungen zusammengehöriger Klemmbacken ineinandergreifend ausgebildet und verlaufen schräg zur Bewegungsrichtung. Als beweglicher Träger für die Klemmbacken kann ein umlaufender hohler oder voller Förderzylinder, Ringkörper, Segmentkörper o. dgl. verwendet werden. The purpose of the invention is to remedy these deficiencies and to create a machine on which an operationally reliable automatic hot sealing the workpieces, such as bags in particular, is ensured. This is achieved in that on a machine of the aforementioned type, the jaws of which the one fixed to the movable carrier and the other movable thereto, such as. B. pivotable, is arranged, are formed like pliers. There are for the movable jaw Means for their resilient pressing against the fixed jaw and means too their temporary lifting from the fixed jaw at the beginning and at the end of the Conveying path provided for the individual workpieces. Before the point of the trajectory the clamping jaws, on which this is achieved by heating and pressing at the connecting seams A sticky workpiece is released by opening the clamping jaws is an in Holding device controlled as a function of the conveying movement of the clamping jaws intended for the workpiece. The feeder facility for the workpieces, the means for temporarily opening the heated jaws and the drive means for the jaw support and the retaining device are so in cooperation brought that the workpieces automatically heat-bonded in a continuous operation will. When using clamping jaws corrugated on their Ireßflächen the Corrugations of associated clamping jaws are formed and run in interlocking fashion oblique to the direction of movement. As a movable support for the clamping jaws, a Circumferential hollow or full delivery cylinder, ring body, segment body or the like. be used.
