Die Enden der Anschlußdrähte 423 und 433 sind an eine elektrische Heizeinrichtung 40 angeschlossen. FIG. 3 shows a heated sealing wheel 4 with a base part 41 , which has two metal ring supports 411 , 412 as positive and negative electrodes. The two metal ring supports 411 and 412 serve for the rotatable mounting of contact rings 42 , 42 . The contact rings 42 and 43 are connected to a power source. An insulation ring 44 for electrical insulation of the two electrodes is provided between the contact rings 42 and 43 . The contact rings 42 , 43 have threaded holes 421 , 431 for threaded bolts 422 , 432 , which are used for connecting connecting wires 423 and 433 . The contact ring 43 is formed with a hole 434 for the insertion of the connecting wire 423 . Hole 434 may be formed with an insulator to prevent a short circuit between lead 423 and contact ring 43 . The insulating ring 44 is fixed to a shaft rod 45 , one end of which has a gear 46 and the other end of which extends through a shaft hole 471 of a fixed plate 47 and a shaft hole 481 of a fixed disk 48 , in order to establish a connection with the sealing wheel 49 . The shaft rod 45 is formed with two slots 451 through which the connecting wires 423 and 433 extend. The ends of the lead wires 423 and 433 are connected to an electric heater 40 .

Die fixierte Scheibe 48 weist Löcher 482 auf, durch die sich Bolzen 483 erstrecken, um die fixierte Scheibe 48 an Gewindelöchern 472 der ortsfesten Platte 47 zu befestigen. Das Zentrum der fixierten Scheibe 48 ist mit einem Lager 484 zur drehbaren Lagerung der Wellenstange 45 versehen.The fixed washer 48 has holes 482 through which bolts 483 extend to secure the fixed washer 48 to threaded holes 472 of the fixed plate 47 . The center of the fixed disc 48 is provided with a bearing 484 for rotatably supporting the shaft rod 45 .

Das Abdichtungsrad 49 ist mit der Wellenstange 45 mittels eines Bolzens 491 verbunden. Das Abdichtungsrad 49 weist zum Einstecken einer elektrischen Heizeinrichtung 40 ein rundes Loch 492 auf, wobei die elektrische Heizeinrichtung 40 mittels eines Bolzen 493 befestigt ist.The sealing wheel 49 is connected to the shaft rod 45 by means of a bolt 491 . The sealing wheel 49 has a round hole 492 for inserting an electrical heating device 40 , the electrical heating device 40 being fastened by means of a bolt 493 .

Die Ober- bzw. Mantelfläche des Abdichtungsrades 49 ist strukturiert. Das Abdichtungsrad 49 ist zum Aufheizen mit einer Stromquelle verbunden. Durch Anpassung an ein unteres Abdichtungsrad 49′ dichtet das Abdichtungsrad 49 die Öffnungen von Taschen und prägt diese, wie aus Fig. 4 ersichtlich ist.The upper or outer surface of the sealing wheel 49 is structured. The sealing wheel 49 is connected to a power source for heating. By adapting to a lower sealing wheel 49 ', the sealing wheel 49 seals the openings of pockets and shapes them, as can be seen from Fig. 4.

Fig. 5 zeigt ein Abdichtungsrad 49 und ein Prägerad, die voneinander beabstandet sind, um eine Beschädigung der Taschen zu vermeiden, die z. B. aus PP- oder PE-Kunststoffmaterial bestehen. Das in seinem Inneren eine elektrische Heizeinrichtung 40 aufweisende Abdichtungsrad 49 weist zum Abdichten von Taschen eine glatte Ober- bzw. Mantelfläche auf. Zwei Prägeräder 5 und 5′ sind hinter dem Abdichtungsrad 49 angeordnet. Das Prägerad 5 ist mit der Welle 51 verbunden, die sich mit der daran fixierten Scheibe 52 dreht. Am einen Ende der Welle 51 ist ein Zahnrad 53 befestigt, an dem eine Kette 54 kämmt, um das Zahnrad 46 des aufgeheizten Abdichtrades 4 anzutreiben, so daß das Prägerad 5 und das Abdichtungsrad 49 sich synchron drehen können. Dann können die abgedichteten Plastiktaschen geprägt werden. Fig. 5 shows a sealing wheel 49 and an embossing wheel, which are spaced apart to avoid damage to the pockets, which, for. B. consist of PP or PE plastic material. The sealing wheel 49, which has an electrical heating device 40 in its interior, has a smooth upper or outer surface for sealing pockets. Two embossing wheels 5 and 5 'are arranged behind the sealing wheel 49 . The embossing wheel 5 is connected to the shaft 51 , which rotates with the disk 52 fixed thereon. At one end of the shaft 51 , a gear 53 is attached, on which a chain 54 meshes to drive the gear 46 of the heated sealing wheel 4 , so that the embossing wheel 5 and the sealing wheel 49 can rotate synchronously. Then the sealed plastic bags can be embossed.

Aus den Zeichnungen ergibt sich, daß die erfindungsgemäße Abdichtmaschine einfacher ausgebildeter ist als die herkömmlichen Abdichtungsmaschinen der gattungsgemäßen Art. Der Abdichtvorgang und der Prägevorgang zum Abdichten aus unterschiedlichen Materialen können voneinander getrennt sein oder gemeinsam durchgeführt werden.From the drawings it follows that the invention Sealing machine is simpler than that conventional sealing machines of the generic type Sealing process and the stamping process for sealing off different materials can be separated from each other or be carried out together.
