Hierbei stellt die Beutelhalterung gleichzeitig die Vorrichtung zum Überführen der Beutel an die Füllen und Schließeinrichtung dar, so daß die Kühleinrichtung der Beutelübergabevorrichtung zugeordnet ist.This machine has a transfer device for the bags, which is assigned a cooling device in the form of cooling jaws, which the welded The bottom seam of the bag cools before it is filled. The cooling jaws are an indispensable part of this Part of the locking device. Here, the bag holder is at the same time represents the device for transferring the bags to the filling and closing device, so that the cooling device is assigned to the bag transfer device.

Mehrfach bekannt ist auch die Verwendung von aus Rohren oder Düsen austretende Blasluft zum Kühlen von Schweißnähten an Kunststoffpackungen (deutsche Patentschrift 809 056, USA-Patentschriften 2691 474 und 3053 386). Ferner ist bekannt die Anordnung mehrerer schwenkbarer Sauger zum Zuführen von Beuteln. An sich bekannt sind schwenkbare Sauger für die Übergabe von Beuteln (deutsche Patentschrift 1 035 557). Schließlich ist es bekannt, eine kombinierte Schweiß- und Vorziehvorrichtung für Schlauchbeutel gleichzeitig als Kühlwerkzeug auszubilden (USA-Patentschrift 3050 916). Auch wurden schon Vorrichtungen zum Abkühlen einer heißen Siegelnaht während der Bewegung der Pakkungen vorgeschlagen, wobei entweder ein flüssiges Kühlmittel oder auch Kühlluft verwendet wird (britische Patentschrift 731 309 und USA-Patentschrift 2037 903). Die hier verwendeten Kühlvorrichtungen sind wiederum unabdingbare Bestandteile der Schweiß- und Siegelvorrichtungen der betreffenden Maschine und dienen dem Zweck, die Schweißstellen unter einem bestimmten Druck abzukühlen.The use of pipes or nozzles is also known several times Exiting blown air for cooling weld seams on plastic packaging (German Patent 809 056, U.S. Patent 2691 474 and 3053 386). It is also known the arrangement of several swiveling suction cups for feeding bags. Known per se are swiveling suction cups for the transfer of bags (German patent specification 1 035 557). Finally, a combined welding and pre-drawing device is known for tubular bags to be designed as a cooling tool at the same time (USA patent 3050 916). Devices for cooling a hot sealed seam have also been used Proposed during the movement of the packages, using either a liquid coolant or cooling air is used (British patent 731 309 and USA patent 2037 903). The cooling devices used here are in turn indispensable components the welding and sealing devices of the machine concerned and serve the purpose of to cool the welds under a certain pressure.
