Ein Umschnürungsverfahren dieser Art ist bekannt aus der US-PS 35 43 675.A strapping method of this type is known from the U.S. Patent No. 35 43 675.

Bei dem bekannten Umschnürungsverfahren wird das Ende der das Paket umhüllenden Bandschlaufe von dem zur Vorratsspule führenden Teil des Bandes abgetrennt und in eine Position gebracht, in der es den Anfang der Bandschlaufe überlappt. Die Verschlußeinheit stülpt über die einander überlappenden Enden der Bandschlaufe eine Hülse und verkrimpt diese Hülse mit den Packbandenden.In the known tying method, the end of the the package-wrapping tape loop from the to the supply reel leading part of the tape severed and into position in which it overlaps the beginning of the ribbon loop. The closure unit slips over the overlapping one another Ends of the band loop a sleeve and crimped this sleeve with the packing tape ends.

Aus der DE-OS 33 46 598 ist es bekannt, die einander über­ lappenden Bandenden einer ein Paket oder einen Stapel um­ hüllenden Bandschlaufe im Ultraschall-Schweißverfahren miteinander zu verschweißen. Das Ultraschall-Schweißverfah­ ren hat den Vorteil, daß Erwärmungen nach außen hin nicht in Erscheinung treten und das Verschweißen bei sofortiger Betriebsbereitschaft schnell erfolgt.From DE-OS 33 46 598 it is known that each other lapping band ends around a package or stack enveloping band loop in the ultrasonic welding process to weld together. The ultrasonic welding process ren has the advantage that outside warming is not possible Appear appearance and the welding with immediate Ready for operation quickly.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zum Umschnüren von Paketen oder Stapeln der eingangs genannten Art so zu verbessern, daß mit relativ geringem maschinellen Aufwand die Vorteile des Ultraschall-Schweißverfahrens genutzt werden können und die Pakete oder Stapel in schnel­ ler Folge zuverlässig mit Band aus Kunststoff umschnürt werden können.The invention has for its object a method for Tying up packages or stacks of the aforementioned  Art to improve so that with relatively little mechanical The advantages of the ultrasonic welding process can be used and the packages or stacks in no time As a result, reliably tied with plastic tape can be.

Diese Aufgabe wird nach der Erfindung dadurch gelöst, daß der Bandüberbringer beim Zuführen des Bandendes zum Bandan­ fang eine offene Schlaufe oder Einfaltung bildet und beide Lagen der offenen Schlaufe oder Einfaltung mit dem Bandan­ fang im Ultraschall-Schweißverfahren zusammengeschweißt und die äußere Lage der offenen Schlaufe oder Einfaltung vom zur Vorratsspule führenden Band abgetrennt wird, nachdem die Zange den Bandanfang für die nächste Umschnürung erfaßt hat.This object is achieved according to the invention in that the tape deliverer when feeding the tape end to the tape catch an open loop or fold and forms both Lay the open loop or fold in with the bandan welded together in the ultrasonic welding process and the outer layer of the open loop or folding from to Supply reel leading tape is cut off after the Pliers has grasped the beginning of the band for the next tying.

Durch diese zweifache Überlappungsschweißung wird ferner erreicht, daß die überlappenden Teile des Bandes in ganzer Länge mit der das Paket oder den Stapel umschlingenden Bandschlaufe verschweißt ist und nicht vom Paket oder Stapel absteht. Dadurch können Verletzungen und unbeabsichtigtes Aufreißen der Umschnürung vermieden werden.This double overlap welding is also achieved that the overlapping parts of the tape in whole Length with which the package or stack is looped Belt loop is welded and not from the package or stack protrudes. This can cause injuries and accidental Avoid tearing the strapping.

Durch Abschneiden der Umschnürung wird unterhalb der Bewe­ gungsebene der Pakete oder Stapel ein neuer Bandanfang gebildet, der von einer Zange festgehalten wird, so daß sich auch ein neuer Bandvorhang bildet. Die Umschnürungsvorrich­ tung steht für einen neuen Arbeitszyklus bereit.By cutting off the strapping is below the Bewe level of the packets or stacks a new beginning of the tape formed, which is held by pliers, so that a new band curtain also forms. The strapping device tion is ready for a new work cycle.

In der folgenden Beschreibung ist das Verfahren näher erläutert:In the following description is the procedure explained in more detail:

In Fig. 1 bildet ein Band 6 aus verschweißbarem Kunststoff zwischen einer Vorratsspule 1 und einem Bandanfang, der unterhalb der Bewegungsebene 5 der Pakete oder Stapel 4 zwischen einer Unterzange 2 und einer Oberzange 3 festgehal­ ten wird, einen Bandvorhang. In Fig. 1, a tape 6 made of weldable plastic between a supply reel 1 and a beginning of the tape, which is festgehal th below the plane of movement 5 of the packages or stack 4 between a pair of tongs 2 and a top tongs 3 , a tape curtain.

In Fig. 2 hat das Paket oder der Stapel 4 den Bandvorhang 6 auf drei Seiten um sich gehüllt. Eine Schweißgegenplatte 8 wird in die Umreifungsebene zwischen der Oberseite des Bandanfangs und der Unterseite des Paketes oder Stapels 4 geschoben. Eine linke Zange 7 hält das Band 6 unter der Schweißgegenplatte 8 fest. Die rechte Oberzange 3 gibt den Bandanfang frei, ein Glattstreifer 9 glättet sporadisch den von der Oberzange 3 freigegebenen Bandanfang unter der Schweißgegenplatte 8.In Fig. 2, the package or stack 4 has the ribbon curtain 6 wrapped around it on three sides. A welding counter plate 8 is pushed into the strapping plane between the top of the beginning of the band and the bottom of the package or stack 4 . A left pair of pliers 7 holds the band 6 under the weld counter plate 8 . The right upper gripper 3 is the beginning of the tape free, a smooth-stripper 9 smoothes the sporadically released from the upper gripper 3 beginning of the tape under the weld backing plate. 8

In Fig. 3 legt ein von oben kommender Finger 10 das Band 6 um die hintere Seite des Paketes oder Stapels 4.In FIG. 3, a finger 10 coming from above places the band 6 around the rear side of the package or stack 4 .
