Description

Die Erfindung bezieht sich auf ein Verfahren zum Umschnüren eines Ballens od. dgl., vorzugsweise aus z. B. Chemiefasern, mittels einer metallenen Bandage, die von einer Vorratsspule kommend mit ihrem freien Ende zunächst durch ein bereit gehaltenes metallenes Verbindungselement gefahren, dann um den Ballen geführt, das vorgeschobene freie Ende ein zweites Mal in das Verbindungselement geführt, arretiert, dann durch rückwärtiges Fahren der Bandage durch das Verbindungselement diese Bandage um den Ballen gespannt, das Verbindungselement verpreßt und der noch mit der Vorratsspule verbundene Teil der Bandage geschnitten wird.The invention relates to a method for strapping a bale or the like, preferably from z. B. man-made fibers, by means of a metal bandage coming from a supply reel with its free end first passed through a metal connecting element held ready, then guided around the bale, the advanced free end guided a second time into the connecting element, locked, then by rearward Driving the bandage through the connecting element this bandage is stretched around the bale, the connecting element is pressed and the part of the bandage still connected to the supply reel is cut.

Ein Verfahren dieser Art ist durch die DE-B-1 257 662 bekannt. Dort wird das als metallene Bandage dienende Band hinter dem und mit Abstand vom Verbindungselement durch eine gesonderte Vorrichtung erfaßt und um einen Dorn um 180° verbogen. Nach Entfernen dieser Biegevorrichtung und beim anschließenden Spannen des Bandes um den Ballen rutscht die somit hergestellte Schlaufe über das Verbindungselement, mit dem die beiden übereinander liegenden Bänder verpreßt werden. Das Verbindungselement ist ebenfalls ein Metallband, das zur Herstellung einer Rundumschließe zweifach U-förmig gebogen und dann - aber mit einer offenen Naht - verpreßt wird. Dieses Verfahren zum Verschließen der Bandage ist sehr aufwendig in der Konstruktion und die Bandage selber nicht sehr haltbar.A method of this type is known from DE-B-1 257 662. There, the band serving as a metal bandage behind and at a distance from the connecting element is gripped by a separate device and bent by a mandrel by 180 °. After removal of this bending device and subsequent tensioning of the band around the bale, the loop thus produced slips over the connecting element with which the two bands lying one above the other are pressed. The connecting element is also a metal band, which is bent twice in a U-shape to produce an all-round clasp and then - but with an open seam - pressed. This method of closing the bandage is very complex to construct and the bandage itself is not very durable.

Ein vorteilhafteres Umschnürungsverfahren geht aus der EP-A-093 953 als bekannt hervor. Die dort offenbarte Vorrichtung hat den Vorteil, daß eine dauerhafte Umreifung eines Faserballens mittels eines Drahtes möglich gemacht ist, wobei die Drahtenden durch eine Plombe aus einem rohrförmigen Metallstück miteinander verbunden werden. Dies erfolgt, indem das um den Ballen geschlungene Drahtstück mit Abstand vom Ende von einer Halte- und Verschlußeinrichtung erfaßt, auf diesen frei herausstehenden Endabschnitt ein Metallröhrchen aufgeschoben, der andere zunächst mit der Vorratsspule verbundene Endabschnitt dieses Drahtes in einer vorbestimmten Länge geschnitten, ebenfalls mit Abstand vom Ende von einer Halte- und Verschlußeinrichtung erfaßt, der Draht gespannt, der Endabschnitt durch das auf den anderen Endabschnitt gestülpte Metallröhrchen geschoben und schließlich dieses Röhrchen zur Herstellung der Plombe verpreßt wird.A more advantageous strapping method is known from EP-A-093 953. The device disclosed there has the advantage that a permanent strapping of a fiber bale is made possible by means of a wire, the wire ends being connected to one another by a seal made of a tubular metal piece. This is done by gripping the piece of wire wrapped around the bale at a distance from the end by a holding and closing device, sliding a metal tube onto this freely protruding end section, cutting the other end section of this wire, which is initially connected to the supply spool, to a predetermined length, likewise at a distance gripped from the end by a holding and closing device, the wire is tensioned, the end section is pushed through the metal tube placed on the other end section and finally this tube is pressed to produce the seal.

Es hat sich herausgestellt, daß diese Arbeitsfolge zur Herstellung einer Plombenverbindung nicht in allen Anwendungsfällen eine dauerhafte Verbindung gewährleistet. Es ist z. B. beim Pressen von Chemiefaserballen nicht zu vermeiden, daß die Abmaße dieses Ballens einmal größer oder kleiner sind. Die Bandage muß sich aber der Umfangsfläche des Ballens anpassen, was schwierig ist, wenn die Bandage vor der Plombierung auf ein bestimmtes Maß abgeschnitten ist. Auch ist es schwierig, den Draht mit Abstand vom Ende durch eine Vorrichtung lösbar zu erfassen und das Metallröhrchen über diesen Abschnitt zu schieben. Diese Bewegungsvorgänge sind nur schwer ohne Unterbrechungen zu automatisieren. Auch besteht die Gefahr, daß die Halte- und Verschlußeinrichtung den Draht beim Umklammern verformt, so daß nach Herstellung der Plombe ein Lösen der Klemmvorrichtung von dem Draht nicht mehr möglich ist.It has been found that this work sequence for producing a seal connection does not guarantee a permanent connection in all applications. It is Z. B. when pressing chemical fiber bales not to avoid that the dimensions of this bale are once larger or smaller. However, the bandage has to adapt to the circumferential surface of the bale, which is difficult if the bandage is cut to a certain size before the sealing. It is also difficult to detachably grasp the wire at a distance from the end by means of a device and to slide the metal tube over this section. These movements are difficult to automate without interruptions. There is also the danger that the holding and closing device deforms the wire when it is clipped, so that after the seal has been produced, it is no longer possible to detach the clamping device from the wire.

Ausgehend von dem aus der DE-B-1 257 662 bekannten Verfahren liegt der Erfindung die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zur Durchführung dieses Verfahrens zu entwickeln, mit dem eine dauerhafte, feste Umschnürung eines Ballens od. dgl. hergestellt werden kann, die aus einem Draht und als Bindeverschluß aus einer rundum geschlossenen Plombe hergestellt wird, wobei der Ballen eine beliebige Form bzw. beliebige Abmaße haben kann, ohne daß zum Spannen der Schlinge der Draht lösbar erfaßt werden muß, und ohne daß die Gefahr besteht, daß der notwendige Drahtabschnitt rund um den Ballen zuvor zu kurz oder zu lang abgeschnitten ist.On the basis of the method known from DE-B-1 257 662, the object of the invention is to develop a method and a device for carrying out this method, with which a permanent, firm strapping of a bale or the like can be produced, which is made from a wire and as a binding closure from an all-round sealed seal, the bale can have any shape or dimensions, without the wire must be detachably gripped for tensioning the loop, and without the risk that the necessary wire section around the bale is previously cut too short or too long.

Zur Lösung dieser Aufgabe sieht die Erfindung vor, daß die als Draht ausgebildete Bandage ein rundum geschlossenes Metallröhrchen als Verbindungselement durchfährt und ein kurzes Stück des freien, vorher um den Ballen gefahrenen Drahtendes zum Arretieren um das Ende des Metallröhrchens verbogen wird.To achieve this object, the invention provides that the bandage formed as a wire passes through a completely closed metal tube as a connecting element and a short piece of the free end of the wire, previously run around the bale, is bent for locking around the end of the metal tube.

Da auch bei diesem Verfahren der Draht erst nach Herstellung der Plombe von der Vorratsspule abgeschnitten wird, sind die Außenabmasse des Ballens für die Herstellung einer dauerhaften Verbindung gleichgültig. Auch braucht der Draht weder zum Spannen um den Ballen noch zur Herstellung der Plombe lösbar erfaßt zu werden, so daß eine Halte- und Verschlußeinrichtung der bekannten Art bei dem neuen Verfahren entfallen kann.In this method too, since the wire is only cut from the supply spool after the seal has been produced, the outer dimensions of the bale are irrelevant for the establishment of a permanent connection. The wire does not need to be detachably gripped either for tensioning around the bale or for producing the seal, so that a holding and closing device of the known type can be dispensed with in the new method.

Die Verbiegung des Endes kann nach Herstellung der Plombe durch Geraderichten des Drahtes wieder aufgehoben werden, so daß eine evtl. Verletzung einer Person durch das verbogene Ende oder eine Beschädigung des Verpackungsgutes vermieden werden kann.The bending of the end can be canceled again after straightening the seal by straightening the wire, so that possible injury to a person through the bent end or damage to the packaged goods can be avoided.

Die Vorrichtung zur Durchführung dieses Verfahrens geht aus der EP-A-093 953 hervor. Die neue Vorrichtung kennzeichnet sich dadurch,daß

  • a) das von dem Magazin gelieferte Metallröhrchen in Arbeitsstellung, und zwar in die Bewegungsbahn des den Ballen umschlingenden Drahtes verbringbar ist,
  • b) dazu an dem Umschnürungswagen ein verschwenkbar gehaltener Arm angeordnet ist, der am freien Ende mit Haltefingern für das Metallröhrchen versehen ist, die im eingeschwenkten Zustand das Metallröhrchen der Bewegungsbahn der Bandage zuordnen und im ausgeschwenkten Zustand dem bereitstehenden Metallröhrchen-Magazin zugeordnet sind,
  • c) ein zusätzlicher Führungskanal zum Leiten des vorgeschobenen freien Endes des Drahtes erneut in das Metallröhrchen am Umschnürungswagen,
  • d) weiterhin eine Einrichtung zum arretierenden Verbiegen des freien Drahtendes an dem Metallröhrchen und schließlich
  • e) eine Schneideinrichtung zum Abtrennen des um den Ballen verspannten Drahtes von der Vorratsspule nach dem Verplomben vorgesehen sind.
The device for carrying out this method emerges from EP-A-093 953. The new device is characterized in that
  • a) the metal tube supplied by the magazine can be brought into the working position, specifically in the path of movement of the wire wrapping around the bale,
  • b) for this purpose, a pivotably held arm is arranged on the strapping carriage, which is provided at the free end with holding fingers for the metal tube, which in the pivoted-in state assign the metal tube to the movement path of the bandage and, in the pivoted-out state, to the bandage available metal tube magazine are assigned,
  • c) an additional guide channel for guiding the advanced free end of the wire again into the metal tube on the strapping carriage,
  • d) further a device for locking the free wire end on the metal tube and finally
  • e) a cutting device for separating the wire braced around the bale from the supply reel after the sealing is provided.

Diese Merkmale können durch weitere Details vorteilhaft ausgestaltet werden. Sie gehören zum Gegenstand der Erfindung und sind in der Figurenbeschreibung im einzelnen erläutert.These features can be advantageously configured by further details. They belong to the subject of the invention and are explained in detail in the description of the figures.

In der Zeichnung ist ein Ausführungsbeispiel der Vorrichtung im einzelnen dargestellt. Es zeigen:

  • Figur 1: eine Faserballenpresse im Bereich des zu umschnürenden Ballens mit einer seitlich des Ballens verfahrbaren Umschnürungseinrichtung,
  • Figur 2: eine Einrichtung zum automatischen Versorgen der Umschnürungseinrichtung mit jeweils einem Metallröhrchen und
  • Figur 3: in vergrößerter Darstellung die Einzelheit A, nach Figur 1.
In the drawing, an embodiment of the device is shown in detail. Show it:
  • FIG. 1: a fiber baler in the area of the bale to be strapped with a strapping device which can be moved laterally of the bale,
  • Figure 2: a device for automatically supplying the strapping device each with a metal tube and
  • Figure 3: in an enlarged view, the detail A, according to Figure 1.

Die in Figur 1 dargestellte Faserballenpresse zum Pressen eines Ballens 1 besteht aus einem Preßstempel 2 und einer Gegendruckplatte 3. Zum Verpressen der Fasern umschließt die vier jetzt freien Seitenflächen des Ballens 1 ein Pressenmantel 4, der nach Beendigung des Preßvorganges jetzt zur Umschnürung des Ballens 1 nach oben von dem Ballen 1 abgezogen ist. Der an vier Seiten freie, im gepreßten Zustand durch den Preßstempel 2 gehaltene und an den sechs Umfangsflächen mit Vorteil vorher verpackte Ballen 1 wird durch eine rechts neben dem Ballen 1 stehende und am Ballen vorbei verfahrbare Verschnürungseinrichtung 5 mit mehreren Bandagen versehen Voraussetzung dazu ist zunächst, daß sowohl der Preßstempel als auch die Gegendruckplatte 3 Führungskanäle aufweisen, durch die ein Draht eingeschoben werden kann. Auf der der Umschnürungseinrichtung gegenüberliegenden Seite des Ballens 1 ist zusätzlich eine rückseitige Einrichtung 6 lösbar befestigt, mit der die durch die Gegendruckplatte 3 zunächst eingefädelten Drähte automatisch nach oben gebogen und durch den Preßstempel 2 zur Umschnürungseinrichtung 5 zurückgelenkt werden (strichpunktierte Linie).The fiber baling press shown in FIG. 1 for pressing a bale 1 consists of a press ram 2 and a counter pressure plate 3. To compress the fibers, the four now free side surfaces of the bale 1 enclose a press jacket 4, which now closes the bale 1 after the pressing process has ended is withdrawn from the top of the bale 1. The bale 1, which is free on four sides, held in the pressed state by the press die 2 and advantageously previously packaged on the six peripheral surfaces, is provided with a plurality of bandages by a lacing device 5 which stands to the right of the bale 1 and can be moved past the bale. that both the press ram and the counter pressure plate have 3 guide channels through which a wire can be inserted. On the side of the bale 1 opposite the strapping device, a rear device 6 is additionally detachably fastened, with which the wires initially threaded through the counterpressure plate 3 are automatically bent upwards and are guided back to the strapping device 5 by the ram 2 (dash-dotted line).

Die Umschnürungseinrichtung 5 besteht aus einem Gestell 7, das auf dem Boden und über einen an der Presse befestigen Träger 8 am Ballen 1 verfahrbar angeordnet ist. Diese Verfahrbarkeit der Umschnürungseinrichtung ist für das dargestellte Ausführungsbeispiel von Bedeutung, um mehrere Bandagen um den in der Presse gehaltenen Ballen mit nur einer Umschnürungseinrichtung 5 legen zu können. Es ist auch denkbar, den Ballen an der Umschnürungseinrichtung vorbei zu bewegen oder mehrere solche Umschnürungseinrichtungen nebeneinander anzuordnen, die dann die erforderlichen Bandagen legen.The strapping device 5 consists of a frame 7 which is arranged on the bale 1 so as to be movable on the floor and via a support 8 fastened to the press. This movability of the strapping device is important for the exemplary embodiment shown in order to be able to place several bandages around the bale held in the press with only one strapping device 5. It is also conceivable to move the bale past the strapping device or to arrange several such strapping devices next to one another, which then place the required bandages.

An dem Gestell 7 ist um die Achse 9 in Höhe der unteren Längskante des Ballens 1 ein Arm 10 mittels einer Kolbenzylindereinheit 11 verschwenkbar gehalten. An diesem Arm 10 sind sämtliche Details zum Legen der Bandage um den Ballen und auch zum Plombieren angeordnet. Da ist einmal der Drahtvorschub 12, der aus zwei übereinander angeordneten Rollenpaaren besteht, die hintereinander jeweils zwischen sich den Draht 30 in einer Ringnut erfassen und mittels des Motors 13 mit Getriebe 14 sowohl vorwärts als auch rückwärts angetrieben (Doppelpfeil) umlaufen. Unterhalb des Drahtvorschubes 12 ist die Plombier- und Schneideinrichtung 15 angeordnet, die im einzelnen im Zusammenhang mit der Figur 3 beschrieben wird. Weiterhin ist in Höhe des Bandvorschubes 12 an dem Arm 10 ein Führungsarm 18 um die Achse 16 mittels der Druckkolbenzylindereinheit 17 verschwenkbar gehalten, um den durch den Preßstempel 2 vorgeschobenen Draht 30" wieder zurück zur Metallröhrchen-Halteeinrichtung (Fig. 2) führen zu können.On the frame 7, an arm 10 is held pivotably about the axis 9 at the level of the lower longitudinal edge of the bale 1 by means of a piston-cylinder unit 11. All details for placing the bandage around the bale and also for sealing are arranged on this arm 10. There is the wire feeder 12, which consists of two pairs of rollers arranged one above the other, each of which grips the wire 30 in a ring groove between them and rotates both forwards and backwards (double arrow) by means of the motor 13 with gear 14. The sealing and cutting device 15, which is described in detail in connection with FIG. 3, is arranged below the wire feed 12. Furthermore, at the level of the belt feed 12 on the arm 10, a guide arm 18 is held pivotably about the axis 16 by means of the pressure piston cylinder unit 17 in order to be able to guide the wire 30 "pushed back by the press ram 2 back to the metal tube holding device (FIG. 2).

Die Umschnürung des Ballens 1 mit einem Draht 30 erfolgt mit dieser Einrichtung wie folgt. Der von der Vorratsspule 19, die auch getrennt von dem Gestell 7 angeordnet sein kann, kommende Draht 30 wird mittels des Drahtvorschubes 12 durch ein bereitgehaltenes Metallröhrchen 20 (Fig. 3) geschoben und dann durch die Führungskanäle in der Gegendruckplatte 3, in der rückseitigen Einrichtung 6 und in dem Preßstempel 2 wieder zurück zur Umschnürungseinrichtung 5 geführt. Von dort läuft der Draht 30" selbsttätig in den Führungskanal des Führungsarms 18 und damit zurück zu dem Metallröhrchen 20 und durch dieses erneut hindurch. Beim zweiten Fahren des Drahtes 30" durch das Metallröhrchen 20 wird durch einen Endschalter der Bandvorschub 12 abgeschaltet, anschließend das freie Drahtende an dem Metallröhrchen 20 arretiert (siehe dazu Beschreibung der Fig. 3), dann der Führungsarm 18 mit Hilfe des Antriebes 17 um die Achse 16 in die strichpunktierte Stellung verschwenkt und schließlich der Bandvorschub 12 rückwärts gefahren zum Spannen des Drahtes 30 um den Ballen 1, wobei der Draht 30 aus den Führungskanälen an den drei Seiten des Ballens 1 herausgezogen wird. Gleichzeitig wird mit Hilfe des Antriebes 11 der Arm 10 der Umschnürungseinrichtung 5 gegen den Ballen 1 verschwenkt, womit der Draht 30 rund um den Ballen 1 verhältnismäßig fest zur Anlage kommt. Anschließend wird die Plombiervorrichtung gemäß Fig. 3 in Tätigkeit gesetzt und der mit der Vorratsspule 19 in Verbindung stehende Teil des Drahtes 30 von der Plombe 20' abgetrennt. Jetzt kann der Antrieb 11 den Arm 10 der Umschnürungseinrichtung 5 wieder zurück in die in der Fig. 1 dargestellte Stellung verschwenken, womit die Umschnürungseinrichtung 5 parallel zu einer weiteren Umschnürungsebene an dem Ballen 1 vorbei verfahren kann.The strapping of the bale 1 with a wire 30 takes place with this device as follows. The wire 30 coming from the supply spool 19, which can also be arranged separately from the frame 7, is pushed by means of the wire feeder 12 through a metal tube 20 (FIG. 3) and then through the guide channels in the counter-pressure plate 3, in the rear device 6 and in the ram 2 back to the strapping device 5. From there, the wire 30 "automatically runs into the guide channel of the guide arm 18 and thus back to the metal tube 20 and through it again. When the wire 30" passes through the metal tube 20 a second time, the tape feed 12 is switched off by a limit switch, and then the free one The wire end is locked on the metal tube 20 (see description of FIG. 3), then the guide arm 18 is pivoted about the axis 16 into the dot-dash position by means of the drive 17 and finally the tape feed 12 is moved backwards for tensioning the wire 30 around the bale 1 , the wire 30 being pulled out of the guide channels on the three sides of the bale 1. At the same time, the arm 10 of the strapping device 5 is pivoted against the bale 1 with the aid of the drive 11, so that the wire 30 around the bale 1 comes to rest relatively firmly. The sealing device according to FIG. 3 is then activated and the part of the wire 30 connected to the supply spool 19 is separated from the seal 20 '. Now the drive 11 can arm 10 of the Swing the strapping device 5 back into the position shown in FIG. 1, with which the strapping device 5 can move past the bale 1 parallel to a further strapping plane.

In den Figuren 2 und 3 sind die Details der Plombier- und Schneideinrichtung 15 nach Fig. 1 dargestellt. Die Metallröhren-Halteeinrichtung nach Fig. 2 besteht im wesentlichen aus einem an dem Einrichtungsteil 15 um die Achse 22 verschwenkbar gehalteen Arm 23, der mit Hilfe der Druckkolbenzylindereinheit 36 um 90° aus seiner in der Figur 2 dargestellten Arbeitsstellung nach außen verschwenkbar ist. Am oberen freien Ende des Schwenkarmes 23 sind etwa der Länge des Metallröhrchens 20 entsprechend viele federnde Haltefinger 24 befestigt, die das Metallröhrchen 20 beim Einfädeln des Drahtes 30 festhalten. Sind die beiden Drahtenden durch das Metallröhrchen 20 gezogen, so verschwenkt der Arm 23 mit Hilfe des Antriebs 36 in die strichpunktiert eingezeichnete Stellung, so daß jetzt ohne Beeinträchtigung der Haltefinger 24 das Metallröhrchen 20 zur Plombe 20' gemäß Figur 3 verpreßt werden kann. Im ausgeschwenkten Zustand wird jetzt mit Hilfe des Antriebs 25 aus einem Magazin 26 ein neues Metallröhrchen in die Haltefinger 24 geschoben, so daß die geöffneten Preßbacken 27, 28 nach Figur 3 erneut mit einem Metallröhrchen 20 bestückt werden können.FIGS. 2 and 3 show the details of the sealing and cutting device 15 according to FIG. 1. The metal tube holding device according to FIG. 2 essentially consists of an arm 23 which is held on the device part 15 so as to be pivotable about the axis 22 and which can be pivoted outwards by 90 ° from its working position shown in FIG. 2 with the aid of the pressure piston cylinder unit 36. At the upper free end of the swivel arm 23, about the length of the metal tube 20, correspondingly many resilient holding fingers 24 are fastened, which hold the metal tube 20 in place when the wire 30 is threaded. If the two wire ends are pulled through the metal tube 20, the arm 23 pivots with the aid of the drive 36 into the position shown in dash-dot lines, so that the metal tube 20 can now be pressed into the seal 20 'according to FIG. 3 without impairing the holding fingers 24. In the swung-out state, a new metal tube is now pushed into the holding fingers 24 from the magazine 26 with the aid of the drive 25, so that the opened press jaws 27, 28 according to FIG. 3 can be re-equipped with a metal tube 20.

Die Metallröhrchen-Preßvorrichtung gemäß Fig. 3 zur Herstellung einer Plombe 20' besteht aus zwei Preßbacken 27, 28, von denen die mit 27 bezeichnete ortsfest angeordnet ist. Die Preßbacke 28 dagegen bewegt sich zur Herstellung der Plombe 20' in Richtung des Pfeiles 29 auf die Preßbacke 27 zu. Bevor dieser Arbeitsgang jedoch durchgeführt werden kann, wird der von der Vorratsspule 19 kommende Draht 30 durch das von den Haltefingern 24 zwischen den Preßbacken 27 und 28 gehaltene Metallröhrchen 20 gezogen. Auf der Austrittsseite des Metallröhrchens 20 verläßt der Draht 30' die Metallröhrchen-Preßvorrichtung und umschlingt im Anschluß daran den Ballen 1 nach Figur 1 in der dort entsprechend beschriebenen Weise. Mit Hilfe des an der Umschnürungseinrichtung 5 gehaltenen Führungsarmes 18 gelangt dann das freie Ende des Drahtes 30" wieder zurück zur Metallröhrchen-Preßvorrichtung nach Fig. 3 und wird erneut durch das Metallröhrchen 20 geschoben. Nunmehr ist ein an der Rückseite der Preßvorrichtung gehaltener Schieber 31 in die dargestellte Stellung verschoben, so daß die in diesen Schieber 31 eingebrachte Sackbohrung 21 in Höhe der Austrittsöffnung des Metallröhrchens 20 angeordnet ist. Mit Hilfe des Drahtvorschubes 12 stößt also das Ende des Drahtes 30" in die Sackbohrung 21, woraufhin mit Hilfe des Endschalters der Drahtvorschub 12 zum Stillstand kommt. Jetzt bewegt sich der Schieber 31 in Richtung des Pfeiles 32 in die strichpunktiert eingezeichnete Stellung, so daß das aus dem Metallröhrchen 20 herausstehende Ende des Drahtes 30" in Richtung des Pfeiles 32 verbogen wird. Damit wird der Draht 30" an seinem Ende an dem Metallröhrchen 20 arretiert, so daß jetzt der Drahtvorschub 12 entgegengesetzt umlaufend angetrieben werden kann, um das Spannen des Drahtes 30 um den Ballen 1 zu erzielen. Nach dem Spannvorgang liegt die Metallröhrchen-Preßvorrichtung dicht an dem Ballen 1, wie es in Fig. 3 dargestellt ist. Zur Herstellung der Plombe 20' bewegt sich nun der Preßbacken 28 in Richtung des Pfeiles 29 in die strichpunktiert eingezeichnete Stellung, so daß nunmehr eine dauerhafte Verbindung zwischen den beiden Drahtenden 30' und 30" hergestellt ist.The metal tube pressing device according to FIG. 3 for producing a seal 20 'consists of two pressing jaws 27, 28, of which the one designated 27 is arranged in a stationary manner. The pressing jaw 28, on the other hand, moves towards the pressing jaw 27 in the direction of the arrow 29 to produce the seal 20 '. Before this operation can be carried out, however, the wire 30 coming from the supply spool 19 is pulled through the metal tube 20 held by the holding fingers 24 between the press jaws 27 and 28. On the exit side of the metal tube 20, the wire 30 'leaves the metal tube pressing device and then wraps around the bale 1 according to FIG. 1 in the manner described there. With the aid of the guide arm 18 held on the strapping device 5, the free end of the wire 30 "then comes back to the metal tube pressing device according to FIG. 3 and is pushed again through the metal tube 20. Now a slide 31 held on the rear side of the pressing device is in the position shown is shifted so that the blind bore 21 introduced into this slide 31 is arranged at the level of the outlet opening of the metal tube 20. With the help of the wire feeder 12, the end of the wire 30 "pushes into the blind bore 21, whereupon the wire feeder is operated using the limit switch 12 comes to a standstill. Now the slider 31 moves in the direction of the arrow 32 into the position shown in dash-dotted lines, so that the end of the wire 30 "protruding from the metal tube 20" is bent in the direction of the arrow 32. The wire 30 "is thus at its end on the metal tube 20 locked, so that the wire feed 12 can now be driven in the opposite direction in order to achieve the tensioning of the wire 30 around the bale 1. After the tensioning process, the metal tube pressing device lies close to the bale 1, as shown in FIG. 3. To produce the seal 20 ', the press jaw 28 now moves in the direction of the arrow 29 into the position shown in dash-dot lines, so that a permanent connection is now established between the two wire ends 30' and 30 ".

Nach wie vor ist jedoch der Draht 30' mit der Vorratsspule 19 verbunden. Nach der Erfindung erfolgt der Trennvorgang gleichzeitig, jedoch sicherheitshalber verzögert, mit dem Herstellen der Plombe 20'. Dazu sind am Eingang der Preßvorrichtung nach Fig. 3 zwei Schneidstößel 33, 34 aufeinanderzugerichtet angeordnet. Beim Bewegen des Preßbackens 28 in Richtung des Pfeiles 29 bewegen sich damit die Schneidstößel 33, 34 auch aufeinander zu und trennen den Draht 30' von der Vorratsspule 19. Gleichzeitig bewegt sich der Schieber 31 zurück in Richtung des Pfeiles 35 in die mit ausgezogenen Linien dargestellte Stellung, so daß das Ende des Drahtes 30" wieder gerade gebogen wird.However, the wire 30 'is still connected to the supply spool 19. According to the invention, the separation process takes place at the same time, but for safety reasons, with the manufacture of the seal 20 '. For this purpose, two cutting plungers 33, 34 are arranged facing each other at the input of the pressing device according to FIG. 3. When the pressing jaw 28 is moved in the direction of the arrow 29, the cutting plungers 33, 34 also move towards one another and separate the wire 30 'from the supply spool 19. At the same time, the slide 31 moves back in the direction of the arrow 35 into that shown in solid lines Position so that the end of the wire 30 "is bent straight again.
