- a thread cutting device 9, 16 is arranged below the outlet opening 18 and in an area , which lies above the highest fill level in the film tube 8 in order to cut through a possibly remaining material thread, whereupon the ends of this material thread contract by capillary action. In this way, a perfect transverse welding of the film section can be ensured.
- the thread cutting device is shown only schematically, for example it can comprise a (heated) cutting wire 9, which is moved past the outlet opening 18 at the end of a filling process after the outlet opening 18 has been closed by the plunger 15, the latter being moved Cutting wire can be attached to the end of pivot arms 16.
- the filling and shaping device shown in FIG. 2 is operated in a clock-controlled manner, so that the film web is first formed into a film tube 8 with the aid of the longitudinal seam welding device 10 and this film tube is pulled off the molding tube 3 and through the transverse seam welding device is closed. After the transverse weld seam has been formed, the outlet opening 18 of the filling device 20 can be opened and a predetermined amount of material can be filled into the film tube while simultaneously pulling the film tube downwards.
- both the longitudinal seam welding device 10 for further development of the film tube and the transverse seam welding device for closing the section of the film tube which has just been filled with material are actuated, one or more transverse weld seams being produced, which then both form the upper one Form the transverse weld seam of the section of the film tube that has just been filled and the lower cross weld seam of the section that is still to be filled.
- a film tube limited only by the length of the film web fed to a feed roll can be filled with the material, this material being arranged in individual sections 32 (FIG. 1) in the film web by the timing control.
- an absolutely continuous operation can be achieved by welding a new film web to the end of a used supply roll.
- the thread cutting device ensures that an absolutely safe and firm design of the transverse weld seams is achieved, so that there is no risk of the material escaping from the individual sections of the film web.
- cooling devices for the film tube 8 can of course be provided in the region of the outlet end of the filling device 20 and below this, in order to reliably prevent the material of the film tube from melting due to the material filled therein, without it being necessary to cool the material in the filling device to a value that is too low.

Abstract
According to the inventive method for packaging a material, which can be melted onto an object, in a film that is melted on with the material when processing the same, the film is shaped into a film tube (8) which encloses the material. Said film tube is formed out of a film web by wrapping the film web around a hollow shaped body, which at least partially surrounds the lower discharge end (18) of a filling device (20), and by welding the longitudinal edges of the film web together with a longitudinal weld seam. The film tube (8) is removed from the end of the shaped body, is sealed on the free bottom end thereof with at least one lower transversal weld seam, is filled with a predetermined quantity of the material, and is sealed above the level of the filled quantity by at least one additional transversal weld seam that simultaneously forms the lower transversal weld seam for the next filling process. The formation of the longitudinal weld seam, the removal of the film tube from the shaped body, the filling of the material, and the formation of the transversal weld seams are carried out in a timed manner so that the film tube is subdivided into individual sections filled with the material.

Um zu verhindern, daß nachtropfendes Material oder ein Material - faden zwischen dem in den Abschnitt des Folienschlauches abgefüllten Material und der Auslaßöffnung 18 der Füllvorrichtung 20 die Festigkeit der oberen Querschweißnaht beeinträchtigt, ist eine Fadenabschneidvorrichtung 9,16 unterhalb der Auslaßöffnung 18 und in einem Bereich angeordnet, der oberhalb des höchsten Füllstandes in dem Folienschlauch 8 liegt, um einen eventuell verbleibenden Materialfaden zu durchtrennen, worauf sich die Enden dieses Materialfadens durch Kapillarwirkung zusammen- ziehen. Auf diese Weise kann eine einwandfreie Querverschweißung des Folienabschnittes sichergestellt werden.In order to prevent dripping material or a thread of material between the material filled into the section of the film tube and the outlet opening 18 of the filling device 20 from affecting the strength of the upper transverse weld seam, a thread cutting device 9, 16 is arranged below the outlet opening 18 and in an area , which lies above the highest fill level in the film tube 8 in order to cut through a possibly remaining material thread, whereupon the ends of this material thread contract by capillary action. In this way, a perfect transverse welding of the film section can be ensured.
Bei der dargestellten Ausführungsform ist die Fadenabschneidvorrichtung lediglich schematisch dargestellt, sie kann bei- spielsweise einen (beheizten) Schneiddraht 9 umfassen, der an der Auslaßöffnung 18 am Ende eines Füllvorganges nach dem Verschließen der Auslaßδffnung 18 durch den Preßkolben 15 vorbei - bewegt wird, wobei dieser Schneiddraht am Ende von Schwenkarmen 16 befestigt sein kann.In the embodiment shown, the thread cutting device is shown only schematically, for example it can comprise a (heated) cutting wire 9, which is moved past the outlet opening 18 at the end of a filling process after the outlet opening 18 has been closed by the plunger 15, the latter being moved Cutting wire can be attached to the end of pivot arms 16.
Die Betriebsweise der in Fig. 2 gezeigten Füll- und Formungs- einrichtung erfolgt taktgesteuert, so daß die Folienbahn zunächst mit Hilfe der Längsnaht-Schweißvorrichtung 10 zu einem Folienschlauch 8 geformt und dieser Folienschlauch von dem Form- röhr 3 abgezogen und durch die Quernaht-Schweißvorrichtung verschlossen wird. Nach dem Ausbilden der QuerSchweißnaht kann die Auslaßöffnung 18 der FüllVorrichtung 20 geöffnet werden und eine vorgegebene Materialmenge unter gleichzeitigem weiterem Abziehen des Folienschlauches nach unten hin in den Folienschlauch einge- füllt werden. Nach dem Abfüllen dieser vorgegebenen Menge wird erneut sowohl die Längsnaht-Schweißvorrichtung 10 zur weiteren Ausbildung des Folienschlauches als auch die Quernaht-Schweißvorrichtung zum Verschließen des soeben mit Material gefüllten Abschnittes des Folienschlauches betätigt, wobei eine oder mehrere Querschweißnähte hergestellt werden, die dann sowohl die obere Querschweißnaht des gerade gefüllten Abschnittes des Folienschlauches als auch die untere Querschweißnaht des noch zu befüllenden Abschnittes bilden.
Auf diese Weise kann ein lediglich durch die Länge der auf eine Zuführungsrolle zugeführten Folienbahn begrenzte Folienschlauch mit dem Material befüllt werden, wobei durch die Takt- Steuerung dieses Material in einzelnen Abschnitten 32 (Fig. 1) in der Folienbahn angeordnet wird. Selbstverständlich kann durch Anschweißen einer neuen Folienbahn an das Ende einer verbrauchten Vorratsrolle ein absolut kontinuierlicher Betrieb erzielt werden.The filling and shaping device shown in FIG. 2 is operated in a clock-controlled manner, so that the film web is first formed into a film tube 8 with the aid of the longitudinal seam welding device 10 and this film tube is pulled off the molding tube 3 and through the transverse seam welding device is closed. After the transverse weld seam has been formed, the outlet opening 18 of the filling device 20 can be opened and a predetermined amount of material can be filled into the film tube while simultaneously pulling the film tube downwards. After this predetermined quantity has been filled, both the longitudinal seam welding device 10 for further development of the film tube and the transverse seam welding device for closing the section of the film tube which has just been filled with material are actuated, one or more transverse weld seams being produced, which then both form the upper one Form the transverse weld seam of the section of the film tube that has just been filled and the lower cross weld seam of the section that is still to be filled. In this way, a film tube limited only by the length of the film web fed to a feed roll can be filled with the material, this material being arranged in individual sections 32 (FIG. 1) in the film web by the timing control. Of course, an absolutely continuous operation can be achieved by welding a new film web to the end of a used supply roll.
Durch die Fadenabschneidevorrichtung wird erreicht, daß eine absolut sichere und feste Ausbildung der Querschweißnähte erreicht wird, so daß keine Gefahr eines Austritts des Materials aus den einzelnen Abschnitten der Folienbahn besteht.The thread cutting device ensures that an absolutely safe and firm design of the transverse weld seams is achieved, so that there is no risk of the material escaping from the individual sections of the film web.
Obwohl dies nicht dargestellt ist, können selbstverständlich Kühlvorrichtungen für den Folienschlauch 8 im Bereich des Auslaßendes der FüllVorrichtung 20 und unterhalb dieser vorgesehen sein, um ein Aufschmelzen des Materials des Folien- Schlauches durch das in diesen eingefüllte Material sicher zu verhindern, ohne daß es erforderlich ist, das Material in der Füllvorrichtung auf einen zu niedrigen Wert abzukühlen.
Although this is not shown, cooling devices for the film tube 8 can of course be provided in the region of the outlet end of the filling device 20 and below this, in order to reliably prevent the material of the film tube from melting due to the material filled therein, without it being necessary to cool the material in the filling device to a value that is too low.
