In the usual design forms a one-piece (foil) blank by folding the same a pocket with pocket front wall and pocket rear wall for receiving the bag contents. The bag is laterally limited by seams - pocket seams. A filling and removal opening is usually provided with a closure seam. Furthermore, it is customary to form by appropriate extension of the bag rear wall, a closure flap which is foldable against the pocket front wall, folded in the embodiment as a wrap around the bag and fixed to the bag back wall.

Die Erfindung bezieht sich auf eine weiterentwickelte Ausführung derartiger Beutel. Die Verschlusslasche, insbesondere die Wickellasche, ist mit einem einstückigen Fortsatz versehen, der als Schenkel gegen die Innenseite der Verschlusslasche bzw. Wickellasche gefaltet ist und diese abdeckt. Die Verschlusslasche bzw. Wickellasche ist so doppellagig ausgebildet mit einer Außenlage und einer Innenlage. Die beiden Lagen der Verschlusslasche sind durch seitliche (Siegel-)Nähte - Laschennähte - und durch eine Verbindungsnaht miteinander verbunden. Die so geschaffene Verschlusslasche hat eine erhöhte Formstabilität, und darüber hinaus ist an der Innenseite der Verschlusslasche eine bedruckbare bzw. mit Bedruckungen versehene Außenseite der Folie sichtbar.The invention relates to an improved version of such bags. The locking tab, in particular the winding tab, is provided with a one-piece extension, which is folded as a leg against the inside of the locking tab or winding tab and this covers. The locking tab or winding tab is so double-layered with an outer layer and an inner layer. The two layers of the closure flap are by lateral (seal) seams - Laschen seams - and by a Connecting seam connected together. The closure flap thus created has an increased dimensional stability and, moreover, on the inside of the closure flap, a printable or printed side of the film is visible.

Der Erfindung liegt die Aufgabe zugrunde, Beutel der vorstehenden Ausführung hinsichtlich der gestalterischen Ausbildung zu verbessern und darüber hinaus Verfahren und Vorrichtung zum leistungsfähigen, zuverlässigen Herstellen der Beutel vorzuschlagen.The invention has for its object to improve the bag of the above embodiment in terms of design training and beyond to propose method and apparatus for efficient, reliable production of the bag.

Zur Lösung dieser Aufgabe ist der erfindungsgemäße Beutel mit den Merkmalen des Kennzeichens des Anspruchs 1 ausgebildet. Eine Besonderheit des Beutels besteht demnach darin, dass die Lagen der Verschluss- bzw. Wickellasche mit einer Hot-Melt-Naht verbunden sind. Vorteilhaft ist mindestens eine weitere Verbindung der Lagen der Verschluss- bzw. Wickellasche durch Hot-Melt in einem mittigen Bereich. Weiterhin ist mindestens eine vorzugsweise schlitzförmige Öffnung in der Innenlasche angebracht, die - vorzugsweise in Verbindung mit einer Hot-Melt-Naht - die Stabilität der (Wickel-)Lasche erhöht und insbesondere die Verformung von Ecken der Lasche verhindert.To solve this problem, the bag according to the invention with the features of the characterizing part of claim 1 is formed. A special feature of the bag is therefore that the layers of the closure or winding strap are connected to a hot-melt seam. It is advantageous at least one further connection of the layers of the closure or winding strap by hot-melt in a central region. Furthermore, at least one preferably slot-shaped opening in the inner tab is attached, which - preferably in conjunction with a hot-melt seam - increases the stability of the (winding) tab and in particular prevents the deformation of corners of the tab.

Ein erfindungsgemäßes Verfahren zum Herstellen von Beuteln gemäß Anspruch 1 weist die Verfahrensschritte des Anspruchs 5 auf. Die Beutel werden demnach als Abschnitte einer fortlaufenden Folienbahn gefertigt, die in einem ersten Faltschritt Bahnschenkel bildet, einerseits für die Taschen-Vorderwand und andererseits für die Innenlage der Verschluss- bzw. Wickellasche. Eine Faltstation bzw. ein Faltaggregat für die korrekte Faltung der Folienbahn besteht aus einem Faltorgan mit vorzugsweise zwei zusammenwirkenden Faltstücken. Im Anschluss daran werden in einer Siegelstation die längs- und quergerichteten Siegel- bzw. Verbindungsnähte hergestellt, vorzugsweise derart, dass quergerichtete Nähte durch thermisches Siegeln der Folie und längsgerichtete Nähte als Hot-Melt-Nähte (Längsnaht der Lasche) und als Peel-Seal-Naht (Verschlussnaht der Tasche) ausgebildet sind. Die Siegelorgane sind in besonderer Weise ausgebildet. Des Weiteren bezieht sich die Erfindung auf die Handhabung der gewickelten Folienbahn (Bobine).An inventive method for producing bags according to claim 1 comprises the method steps of claim 5. The bags are thus manufactured as sections of a continuous film web, which forms web legs in a first folding step, on the one hand for the pocket front wall and on the other hand for the inner layer of the closure or winding strap. A folding station or a folding unit for the correct folding of the film web consists of a folding member with preferably two cooperating folding pieces. Subsequently, in a sealing station, the longitudinal and transversal sealing or connecting seams are produced, preferably in such a way that transverse seams are achieved by thermal sealing of the film and longitudinal seams as hot-melt seams (longitudinal seam of the tab) and as peel-seal. Seam (closure seam of the bag) are formed. The sealing organs are designed in a special way. Furthermore, the invention relates to the handling of the wound film web (Bobine).

Von Bedeutung sind darüber hinaus Merkmale einer Vorrichtung auf der Grundlage des Anspruchs 9.In addition, features of a device based on claim 9 are of importance.

Es geht um die Ausbildung und Fertigung von Beuteln 10 aus Folie. Gemäß dem gezeigten und bevorzugten Aufbau besteht der Beutel 10 aus einer Tasche 11 und einer Verschlusslasche 12. Die Tasche 11 nimmt den Beutelinhalt auf, insbesondere eine Portion 13 aus geschnittenem Tabak.It is about the training and production of bags 10 made of foil. According to the shown and preferred construction, the bag 10 consists of a pocket 11 and a closing tab 12. The pocket 11 receives the bag contents, in particular a portion 13 of cut tobacco.

Der Beutel 10 besteht vorzugsweise aus einem einzigen, langgestreckten, rechteckigen Zuschnitt der Folie. Durch Umfalten entlang einer (unteren) Faltkante 14 entsteht die Tasche 11 mit Taschen-Vorderwand 15 und Taschen-Rückwand 16. Diese sind seitlich durch (quergerichtete) Taschennähte 17, 18 dauerhaft miteinander verbunden, wobei die Taschennähte 17, 18 vorzugsweise durch thermisches Siegeln hergestellt sind. Die Tasche 11 weist eine Taschenöffnung 19 auf, die das Einfüllen und die Entnahme des Beutelinhalts ermöglicht. Die Taschenöffnung 19 ist durch eine quergerichtete Verschlussnaht 20 verschlossen. Vorzugsweise ist diese als (mehrfach benutzbare) Peel-Seal-Naht ausgebildet.The bag 10 preferably consists of a single, elongate, rectangular blank of the film. By folding along a (lower) folding edge 14, the pocket 11 with pocket front wall 15 and pocket rear wall 16 is formed. These are connected to one another laterally by (transverse) pocket seams 17, 18, the pocket seams 17, 18 preferably being produced by thermal sealing are. The bag 11 has a pocket opening 19, which allows the filling and removal of the bag contents. The pocket opening 19 is closed by a transverse sealing seam 20. Preferably, this is designed as (reusable) peel-seal seam.

Die Taschen-Rückwand 16 ist über die Taschenöffnung 17 hinaus verlängert und bildet die Verschlusslasche 12. Diese wird gegen die Taschen-Vorderwand 15 gefaltet und in Schließstellung mit einem Klebestreifen bzw. einem Tape 21 fixiert. Vorzugsweise ist die Verschlusslasche 12 als Wickellasche ausgebildet, die sich in Schließstellung aufgrund entsprechender Abmessung bis in den Bereich der Taschen-Rückwand 16 erstreckt und mindestens einen der Faltkante 14 zugekehrten Bereich der Taschen-Rückwand 16 abdeckt.The pocket rear wall 16 is extended beyond the pocket opening 17 and forms the closure tab 12. This is folded against the pocket front wall 15 and fixed in the closed position with an adhesive strip or a tape 21. Preferably, the closure tab 12 is formed as a winding tab, which extends in the closed position due to the appropriate dimension into the region of the pocket rear wall 16 and at least one of the folding edge 14 facing portion of the pocket rear wall 16 covers.

Die Verschlusslasche 12 ist in besonderer Weise ausgebildet, nämlich zweilagig mit einer Außenlage 22 und einer Innenlage 23. Die Lagen 22 und 23 liegen dicht aneinander. Die Innenlage 23 wird durch Umfalten der entsprechend verlängerten Verschlusslasche 12 entlang einer Laschenkante 24 gebildet. Vorliegend erstreckt sich die Innenlage 23 im Wesentlichen über die volle Fläche der Verschlusslasche 12 bzw. der Außenlage 22. Die Bemessung und Gestaltung der Innenlage 23 kann hiervon abweichen. Insbesondere kann es sinnvoll sein, dass sich die Innenlage 23 nur in einem Teilbereich der Verschlusslasche 12 erstreckt.The closure tab 12 is formed in a special way, namely two-ply with an outer layer 22 and an inner layer 23. The layers 22 and 23 are close together. The inner layer 23 is formed by folding over the correspondingly extended closure flap 12 along a flap edge 24. In the present case, the inner layer 23 extends substantially over the entire surface of the closure tab 12 and the outer layer 22. The design and design of the inner layer 23 may deviate from this. In particular, it may be expedient that the inner layer 23 extends only in a partial region of the closure flap 12.

Die Lagen 22 und 23 der Verschlusslasche 12 sind (teilweise) miteinander verbunden, um die Relativstellung zu fixieren. Seitliche Verbindungsnähte, nämlich Laschennähte 25, 26 erstrecken sich in Fortsetzung der Taschennähte 17, 18 über die volle Breite der Innenlage 23. Eine Besonderheit sind zusätzliche Verbindungsmittel für die Lagen 22, 23. Bei dem vorliegenden Ausführungsbeispiel ist eine Verbindungsnaht 27 vorgesehen, die vorzugsweise quer zu den Laschennähten 25, 26 verläuft, und zwar unmittelbar entlang einer freien Randkante 28 der Innenlage 23.The layers 22 and 23 of the locking tab 12 are (partially) connected to each other to fix the relative position. Lateral seams, namely tab seams 25, 26 extending in continuation of the pocket seams 17, 18 over the full width of the inner layer 23. A special feature are additional connection means for the layers 22, 23. In the present embodiment, a connecting seam 27 is provided, preferably transversely extends to the Laschennähten 25, 26, and that directly along a free edge 28 of the inner layer 23rd

Die Verbindungsnaht 27 ist als Hot-Melt-Verbindung ausgebildet, also mit Verbindungsmaterial, welches streifenförmig auf den Zuschnitt aufgebracht und nach dem Falten der Lagen 22, 23 durch Wärme und Druck zur Herstellung der Verbindung aktiviert wird. Die Verbindungsnaht 27 ist mit Unterbrechungen ausgebildet, so dass der Bereich zwischen den Lagen 22, 23 entlüftet werden kann. Vorliegend endet die Verbindungsnaht 27 mit Abstand von den Laschennähten 25, 27, so dass (beidseitig) Entlüftungsöffnungen 29 entstehen.The connecting seam 27 is designed as a hot-melt connection, that is to say with connecting material which is applied in strips to the blank and, after folding the layers 22, 23, is activated by heat and pressure to produce the connection. The connecting seam 27 is formed with interruptions, so that the area between the layers 22, 23 can be vented. In the present case, the connecting seam 27 terminates at a distance from the stitched seams 25, 27, so that ventilation openings 29 are formed (on both sides).

Die freie (Innen-)Seite der Innenlage 23 ist mit dekorativer und/oder informativer Bedruckung 30 versehen. In Schließstellung liegt die Innenlage 23 an der Taschen-Vorderwand 15 und vorzugsweise mindestens teilweise an der Taschen-Rückwand 16 an und ist mittels Tape 21 fixiert.The free (inner) side of the inner layer 23 is provided with decorative and / or informative printing 30. In the closed position, the inner layer 23 rests against the pocket front wall 15 and preferably at least partially against the pocket rear wall 16 and is fixed by means of tape 21.

Die Lagen der Verschlusslasche 12 sind - insbesondere zusätzlich zur Verbindungsnaht 27 - mit weiteren Verbindungen versehen, um die Lasche 12 zu stabilisieren. Eine weitere Verbindungsnaht, nämlich eine Zwischennaht 31, ist zwischen den beiden Lagen 22 und 23 angeordnet, und zwar in der Ausführung als Hot-Melt-Verbindung. Die Zwischennaht 31 verläuft parallel zur Verbindungsnaht 27 und ist mit geringerem Abstand von der Laschenkante 24 angeordnet, und endet ebenfalls mit Abstand von den beiden Laschennähten 25, 26.The layers of the closure tab 12 are - in particular in addition to the connecting seam 27 - provided with further connections to stabilize the tab 12. Another connecting seam, namely an intermediate seam 31, is arranged between the two layers 22 and 23, in the embodiment as a hot-melt connection. The intermediate seam 31 runs parallel to the connecting seam 27 and is arranged at a smaller distance from the tab edge 24, and likewise terminates at a distance from the two flap seams 25, 26.

Weiterhin ist die Verschlusslasche 12 im Bereich der Innenlage 23 mit einer Öffnung versehen. Vorliegend ist ein (quergerichteter) Entlastungsschlitz 32 (nur) in der Innenlage 23 angebracht. Dieser ist im Bereich der Zwischennaht 31 angeordnet, wird demnach von dieser eingeschlossen. Diese Konstruktion hat die Wirkung, dass eine Verformung von freien Eckbereichen der Verschlusslasche 12 insbesondere in Schließstellung (gewickelt) vermieden wird. Die Entlastungsöffnung 32 kann alternativ oder zusätzlich aus Stanzlinien oder Perforationslinien 33 bestehen, die in der Innenlage 23 angebracht sind und schräg zur Laschenkante 24, benachbart zu den freien Ecken der Verschlusslasche 12, verlaufen.Furthermore, the closure tab 12 is provided in the region of the inner layer 23 with an opening. In the present case, a (transverse) discharge slot 32 (only) in the inner layer 23 is attached. This is arranged in the region of the intermediate seam 31, is thus included by this. This construction has the effect of avoiding deformation of free corner regions of the closing tab 12, in particular in the closed position (wound). The relief opening 32 may alternatively or additionally consist of punching lines or perforation lines 33, which are mounted in the inner layer 23 and obliquely to the tab edge 24, adjacent to the free corners of the locking tab 12 extend.

Die so ausgebildeten Beutel 10 werden von einer fortlaufenden Folienbahn 34 hergestellt. Diese wird von einem Vorrat abgezogen, nämlich von einer Bobine 35. Die Folienbahn 34 durchläuft mehrere Stationen, und zwar eine Faltstation 36, eine Siegelstation 37 und schließlich eine Trennstation 38 (schematisch in Fig. 12). Die Anordnung ist hier so getroffen, dass die Folienbahn 34 in einer vertikalen Ebene transportiert und bearbeitet wird (bei horizontaler Förderrichtung). Fig. 4 ist demnach eine Draufsicht der Vorrichtung.The thus formed pouches 10 are produced by a continuous film web 34. This is withdrawn from a supply, namely a reel 35. The film web 34 passes through several stations, namely a folding station 36, a sealing station 37 and finally a separation station 38 (shown schematically in FIG Fig. 12 ). The arrangement is made here so that the film web 34 is transported and processed in a vertical plane (in the horizontal conveying direction). Fig. 4 is therefore a plan view of the device.

Die Folienbahn 34 wird vorzugsweise kontinuierlich von der Bobine 35 (mit aufrechter Drehachse) abgezogen und über Umlenkwalzen geführt. Im Bereich eines ersten Förderabschnitts ist ein Splicer 39 angeordnet. Es handelt sich dabei um ein geeignetes (bekanntes) Aggregat zum Verbinden der Bahnen, wenn ein Wechsel der Bobinen 35 stattfindet. Anschließend ist ein Drucker 40 installiert, insbesondere ein Laserdrucker, zum Übertragen von (informativen) Bedruckungen.The film web 34 is preferably withdrawn continuously from the reel 35 (with an upright axis of rotation) and guided over deflecting rollers. In the area of a first conveying section, a splicer 39 is arranged. It is a suitable (known) aggregate for connecting the webs, when a change of the reels 35 takes place. Subsequently, a printer 40 is installed, in particular a laser printer, for transferring (informative) imprints.

Sodann gelangt die Folienbahn 34 in den Bereich der Faltstation 36. Aus einer in Querrichtung versetzten Umlenkstellung wird die Folienbahn 34 schräg geführt zu einer der Faltstation 36 unmittelbar vorgeordneten Umlenkwalze 41. An deren Umfang liegt die Folienbahn 34 mit einem größeren Umschlingungswinkel an. In einer schräggerichteten Ebene gelangt die Folienbahn 34 in den Bereich eines ersten Faltorgans 42.Then, the film web 34 enters the region of the folding station 36. From a transversely staggered deflection, the film web 34 is guided obliquely to a folding station 36 immediately upstream guide roller 41. At the periphery of which lies Film web 34 with a larger wrap angle. In an obliquely directed plane, the film web 34 reaches the region of a first folding member 42.

Im Bereich der Faltstation 36 wird die Folienbahn 34 vorliegend taktweise gefördert, und zwar in Abschnitten entsprechend der Breite mehrerer nebeneinanderliegender Beutel 10, also in Abstimmung mit der Siegelstation 37. Der Förderabschnitt beträgt insbesondere einer Länge für die gleichzeitige Herstellung von drei Beuteln 10. Zwischen der Bobine 35 und der Faltstation 36 ist ein Organ zum Ausgleich der Bewegungen angeordnet, hier ein Pendel 43 mit mehreren Ausgleichswindungen der Folienbahn 34.In the area of the folding station 36, the film web 34 is in this case cyclically conveyed, in sections corresponding to the width of several juxtaposed bag 10, that is in coordination with the sealing station 37. The conveyor section is in particular a length for the simultaneous production of three bags 10. Between the Bobine 35 and the folding station 36 is an organ arranged to compensate for the movements, here a pendulum 43 with several compensating turns of the film web 34th

Die Faltorgane der Faltstation 36 sind so ausgebildet, dass während des Transports der Folienbahn 34 relativ zu den feststehenden Faltorganen zuerst beidseitig Bahnschenkel 44, 45 aufgerichtet werden in eine Zwischenfaltstellung. Dieser Faltschritt erfolgt während des Transports der Folienbahn unter einem spitzen Winkel zu der Hauptförderbahn der fertiggefalteten Folienbahn 34. Das im Wesentlichen plattenförmige Faltorgan 42 ist schräg zur Hauptförderbahn gerichtet, vorzugsweise unmittelbar anschließend an die Umlenkwalze 41. Die Kontur des Faltorgans 42 ist so ausgebildet, dass konvergierende, seitliche Faltränder 46, 47 gebildet sind, um die die Folienbahn 34 unter Bildung der Bahnschenkel 44, 45 herumgefaltet wird. Vorzugsweise ist das Faltorgan 42 als trapezförmige Faltplatte ausgebildet.The folding members of the folding station 36 are designed so that during transport of the film web 34 relative to the fixed folding members first web legs 44, 45 are erected on both sides into an intermediate folding position. This folding step takes place during the transport of the film web at an acute angle to the main conveying path of the finished folded film web 34. The substantially plate-shaped folding member 42 is directed obliquely to the main conveying path, preferably immediately following the deflecting roller 41. The contour of the folding member 42 is designed such that Converging, lateral fold edges 46, 47 are formed, around which the film web 34 is folded around to form the web legs 44, 45. Preferably, the folding member 42 is formed as a trapezoidal folding plate.

Ein weiteres Faltorgan 48 vollendet die Faltung, so dass die Bahnschenkel 44, 45 an einer Seite der Folienbahn 34, nämlich an einem Mittelstreifen 49, anliegen. Das (zweite) Faltorgan 48 schließt an das Faltorgan 42 an. Aufgrund der Relativstellung der vorzugsweise plattenförmigen Faltorgane 42, 48 (unter einem stumpfen Winkel zueinander) wird im Bereich des Faltorgans 48 die Faltung vollendet. Zu diesem Zweck tritt die Folienbahn 34 mit den Bahnschenkeln 44, 45 in der (aufgerichteten) Zwischenfaltstellung in eine keilförmige Ausnehmung 50 des im Wesentlichen V-förmig ausgebildeten Faltorgans 48 ein. Konvergierende Faltränder 51, 52 (übereinanderliegend) führen die Bahnschenkel 44, 45 bis zur vollständigen Anlage aneinander. Das Faltorgan 48 liegt - bezogen auf den Mittelstreifen 49 der Folienbahn 34 - auf der gegenüberliegenden Seite der Folienbahn 34. Die Faltung wird so vollzogen, dass die Bahnschenkel 44, 45 den gewünschten Abmessungen der Taschen-Vorderwand 15 einerseits und der Innenlage 23 der Verschlusslasche 12 andererseits entsprechen. Zwischen den Bahnschenkeln 44, 45 ist ein fortlaufender Folienspalt 53 gebildet.Another folding member 48 completes the folding, so that the web legs 44, 45 rest on one side of the film web 34, namely on a center strip 49. The (second) folding member 48 connects to the folding member 42. Due to the relative position of the preferably plate-shaped folding members 42, 48 (at an obtuse angle to each other), the folding is completed in the region of the folding member 48. For this purpose, the film web 34 enters with the web legs 44, 45 in the (erected) Zwischenfaltstellung in a wedge-shaped recess 50 of the substantially V-shaped folding member 48 a. Converging fold edges 51, 52 (one above the other) guide the web legs 44, 45 together until they are completely in place. The folding member 48 is - based on the median strip 49 of the film web 34 - on the opposite side of the film web 34. The folding is performed so that the web legs 44, 45 the desired dimensions of the pocket front wall 15 on the one hand and the inner layer 23 of the locking tab 12th on the other hand. Between the web legs 44, 45, a continuous film gap 53 is formed.

Die plattenförmigen Faltorgane weisen gerundete Faltränder 46, 47 und/oder 51, 52 auf. Bei einem Faltorgan gemäß Fig. 7 ist ein Faltrand mit Luftschlitzen 54 (oder Luftbohrungen) versehen. Diese dienen zur Zuführung von Luft unter Druck in den Bereich der Umlenkung der Folie zur Faltung. Der Luftschlitz (oder die Luftschlitze) bzw. Luftbohrungen ist bzw. sind an einen Luftkanal 45 im Querschnittsbereich des Faltorgans angeschlossen. Der Luftkanal 55 ist mit einer (regelbaren) Druckluftquelle verbunden (nicht gezeigt). Durch die zugeführte Luft wird im Bereich der Faltränder ein dünnes Luftpolster geschaffen, welches die Reibung für die Folienbahn 34 im Bereich der Faltränder reduziert bzw. vermeidet.The plate-shaped folding members have rounded fold edges 46, 47 and / or 51, 52. In a folding organ according to Fig. 7 a fold edge is provided with louvers 54 (or air holes). These serve to supply air under pressure in the region of the deflection of the film for folding. The air slot (or the air slots) or air holes is or are connected to an air channel 45 in the cross-sectional area of the folding member. The air duct 55 is connected to a (controllable) compressed air source (not shown). By the supplied air, a thin air cushion is created in the region of the folding edges, which reduces or avoids the friction for the film web 34 in the region of the folding edges.

Im Anschluss an die Faltstation 36 wird die Faltung der Bahnschenkel 44, 45 (mechanisch) stabilisiert. Zu diesem Zweck sind Druckwalzen 56, 57 zu beiden Seiten der (gefalteten) Folienbahn 34 angeordnet, derart, dass sie die Bahnschenkel 44, 45 an den Mittelstreifen 46 drücken und dabei insbesondere die Ränder zur Bildung der Faltkante 14 und der Laschenkante 24 stabilisieren.Following the folding station 36, the folding of the web legs 44, 45 is stabilized (mechanically). For this purpose, pressure rollers 56, 57 are arranged on both sides of the (folded) film web 34, such that they press the web legs 44, 45 against the center strip 46 and in particular stabilize the edges for forming the folded edge 14 and the tab edge 24.

Der Entlastungsschlitz 32 im Bereich der Innenlage 23 wird bei dem gezeigten Ausführungsbeispiel im Anschluss an die Faltung der Folienbahn 34 in dem der Innenlage 23 zugeordneten Bahnschenkel 44 angebracht. Zu diesem Zweck wird der Bahnschenkel 44 (örtlich) angehoben. Ein auf der entsprechenden Seite angeordnetes Schneidmesser 58 tritt in den (von dem Mittelstreifen 49 abgehobenen) Bahnschenkel 44 ein und erzeugt einen Schnitt zur Bildung des Entlastungsschlitzes 32. Der Schnitt wird während des Transports der Folienbahn 34 durch das gesteuert bewegbare Schneidmesser 58 hergestellt. Alternativ können Schnitte oder Stanzungen für den Entlastungsschlitz 32 im Bereich der ungefalteten Folienbahn 34 angebracht werden, beispielsweise im Bereich einer Umlenkwalze, wobei als Schneidorgan eine (übliche) Messerwalze eingesetzt werden kann.The relief slot 32 in the region of the inner layer 23 is in the embodiment shown, following the folding of the film web 34 in the inner layer 23 associated Bahnschenkel 44 attached. For this purpose, the web leg 44 is raised (locally). A cutter blade 58 disposed on the corresponding side enters the web leg 44 (lifted from the center strip 49) and forms a cut to form the relief slot 32. The cut is made during transport of the film web 34 by the controllably movable cutting knife 58. Alternatively, cuts or punches for the relief slot 32 in the region of the unfolded film web 34 may be applied, for example in the region of a deflection roller, wherein a (conventional) knife roller can be used as a cutting member.

Der Bahnschenkel 44 kann durch mechanische Mittel (im Bereich des Schneidmessers 58) angehoben werden, vorliegend wird der Bahnschenkel 44 durch ein Schwert 59 angehoben. Neben der Folienbahn 34 bzw. an dem Bahnschenkel 45 ist das Schwert 59 ortsfest angeordnet. Ein freies Ende ist so positioniert, dass der Bahnschenkel 44 durch das Schwert 59 angehoben wird. Im Bereich des freiliegenden Bahnschenkels 44 wird der Schnitt durch das Schneidmesser 58 ausgeführt.The web leg 44 can be lifted by mechanical means (in the area of the cutting knife 58), in the present case the web leg 44 is raised by a sword 59. In addition to the film web 34 and the web leg 45, the sword 59 is arranged stationary. A free end is positioned so that the web leg 44 is raised by the sword 59. In the region of the exposed web leg 44, the cut is made by the cutting knife 58.

Im Anschluss an die Faltstation 36 gelangt die (gefaltete) Folienbahn 34 in den Bereich der Siegelstation 37. In deren Bereich werden durch ein erstes Siegelaggregat 60 (thermische) Verbindungen hergestellt zur Schaffung von Nähten in Längsrichtung der Folienbahn 34. Konkret werden die Verbindungsnaht 27 und/oder die Zwischennaht 31 hergestellt, vorzugsweise durch Aktivierung von streifenförmigem Auftrag für Hot-Melt-Verbindungen. Das betreffende Siegelaggregat 60 ist zu diesem Zweck mit vorzugsweise zwei parallel und mit Abstand übereinander angeordneten, sich in Längsrichtung der Folienbahn 34 erstreckenden Siegelbacken 61 versehen. Diese sind in der Längsabmessung auf die Länge der herzustellenden (Hot-Melt-)Naht ausgerichtet. Das Siegelaggregat 60 ist so gesteuert, dass während einer Stillstandsphase der Folienbahn 34 die (drei) Siegelbacken 61 bzw. Paare von übereinander angeordneten Siegelbacken zur Übertragung von Wärme und Druck gegen die Folienbahn 34 bewegt werden. In einem Arbeitstakt werden demnach drei Beutel 10 vorbereitet.Subsequent to the folding station 36, the (folded) film web 34 enters the region of the sealing station 37. In its region, the first sealing unit 60 (Thermal) compounds made to create seams in the longitudinal direction of the film web 34. Specifically, the seam 27 and / or the intermediate seam 31 are prepared, preferably by activating strip-like order for hot-melt connections. The sealing unit 60 in question is provided for this purpose with preferably two parallel and at a distance one above the other, in the longitudinal direction of the film web 34 extending sealing jaws 61. These are aligned in the longitudinal dimension to the length of the produced (hot-melt) seam. The sealing unit 60 is controlled so that during a standstill phase of the film web 34, the (three) sealing jaws 61 or pairs of stacked sealing jaws for transferring heat and pressure against the film web 34 are moved. Accordingly, three bags 10 are prepared in one working cycle.

Ein zweites, nachfolgendes Siegelaggregat 62 ist in besonderer Weise ausgebildet (Fig. 9). In diesem Bereich werden quer zur Folienbahn 34 gerichtete (aufrechte) Nähte durch thermisches Siegeln der Folie hergestellt, nämlich Doppelnähte 63. Diese entsprechen in der Breite der Abmessung von zwei Taschennähten 17, 18 bzw. Laschennähten 25, 26. Die Doppelnähte 63 werden während einer Stillstandsphase der Folienbahn 34 durch quergerichtete, aufrechte Siegelbacken bzw. Siegelstege 64 hergestellt, von denen mehrere - vorliegend vier - während eines Siegeltaktes zur Anlage an der Folienbahn 34 gebracht werden zur Übertragung von Wärme und Druck. Jeder (aufrechte) Siegelsteg 64 weist eine Unterbrechung auf im Bereich des Folienspalts 53, so dass nur aufeinander ausgerichtete Abschnitte der Doppelnaht 63 erzeugt werden.A second, subsequent sealing unit 62 is designed in a special way ( Fig. 9 ). In this area, directed (upright) seams are produced transversely to the film web 34 by thermal sealing of the film, namely double seams 63. These correspond in width to the dimension of two pocket seams 17, 18 or patch seams 25, 26. The double seams 63 are formed during one Standstill phase of the film web 34 produced by transverse, upright sealing jaws or sealing webs 64, of which several - in the present four - are brought during a sealing cycle to rest on the film web 34 for the transfer of heat and pressure. Each (upright) sealing web 64 has an interruption in the region of the film gap 53, so that only aligned portions of the double seam 63 are generated.

Das Siegelaggregat 62 ist mit Organen versehen, die mindestens im Bereich der Verschlusslasche 12 durch flächigen Druck die Beseitigung von Luft aus dem Bereich zwischen den Lagen 22, 23 der Verschlusslasche 12 bewirken. Vorliegend sind den Siegelstegen 64 Druckplatten 65, 66 zu beiden Seiten der Folienbahn 34 zugeordnet. Diese kommen (etwa) zeitgleich mit den Siegelorganen 64 zur Anlage an der Folienbahn 34, mindestens im Bereich der Verschlusslasche 12 bzw. des (oberen) Bahnschenkels 44. Die Luft wird über die beschriebenen Entlüftungsöffnungen herausgedrückt. Die Druckplatten 65, 66 sind federnd gelagert, nämlich über (vorgespannte) Federn 67, 68. An jedem Siegelsteg 64 sind Druckstücke 69 angebracht, die auf die der zugeordneten Seite angeordneten Federn 67 einwirken und so - zusammen mit den gegenüberliegenden Federn 68 - die Druckplatten 65, 66 beidseitig gegen die Folienbahn 34 drücken. Beim Zurückziehen der Siegelstege 64 (Fig. 9, links) werden die Federn 67, 68 entspannt. Die Druckplatten 65, 66 erhalten einen Abstand voneinander. In dem gebildeten Spalt kann die Folienbahn 34 um einen Arbeitstakt weitergefördert werden. Die Druckplatten 65, 66 weisen Ausnehmungen 70 auf für den Durchtritt der Siegelorgane 64. Diese wirken zusammen mit einem Gegenstück 71 auf der gegenüberliegenden Seite der Folienbahn 34 zusammen. Zwischen Siegelsteg 64 und Gegenstück 71 wird die Folienbahn 34 zur Erzeugung der Siegelnaht bzw. der Doppelnaht 63 eingespannt.The sealing unit 62 is provided with members which cause the elimination of air from the area between the layers 22, 23 of the closure tab 12 at least in the area of the closure tab 12 by surface pressure. In the present case, the sealing webs 64 are assigned printing plates 65, 66 on both sides of the film web 34. These come about at the same time as the sealing members 64 to bear on the film web 34, at least in the region of the closure flap 12 and of the (upper) web leg 44. The air is forced out via the described vent openings. The pressure plates 65, 66 are resiliently mounted, namely via (prestressed) springs 67, 68. At each sealing web 64, pressure pieces 69 are mounted, which act on the springs 67 arranged on the associated side and thus - together with the opposite springs 68 - the pressure plates 65, 66 press on both sides against the film web 34. When retracting the sealing webs 64 ( Fig. 9 , left), the springs 67, 68 relaxed. The pressure plates 65, 66 are spaced apart from each other. In the gap formed, the film web 34 can be further promoted by a power stroke. The printing plates 65, 66 have recesses 70 for the passage of the sealing members 64. These act together with a counterpart 71 on the opposite side of the film web 34 together. Between sealing bar 64 and counterpart 71, the film web 34 is clamped to produce the sealed seam or the double seam 63.

Die unterschiedliche Ausbildung der Verbindungen von Lagen der Folie, nämlich Siegelnähte einerseits und Hot-Melt-Nähte andererseits ermöglicht eine besondere Fertigungstechnik. Die in Längsrichtung der Bahn verlaufenden Nähte bestehen aus Hot-Melt-Material. Dieses wird vorzugsweise bei der Vorbereitung der Folienbahn 34, jedenfalls vor dem Faltprozess, aufgetragen. Wie aus Fig. 5, Fig. 6 ersichtlich, sind mehrere parallele Bahnen aus Hot-Melt-Material bzw. aus Peel-Seal-Material positionsgerecht auf die Folienbahn 34 aufgetragen. Eine Besonderheit besteht darin, dass Bereiche für Hot-Melt-Verbindungen, insbesondere für die Verbindungsnaht 27 und für die Zwischennaht 31, als Streifenabschnitte bzw. Materialabschnitte auftragen. Die Abschnitte 72 aus Hot-Melt sind der Verbindungsnaht 27 zugeordnet. Materialabschnitte 74 gehören zur Zwischennaht 31. Die Hot-Melt-Abschnitte sind so bemessen, dass ein Kontakt mit den (später angebrachten) quergerichteten durch thermisches Siegeln hergestellten Nähten, insbesondere der Laschennähte 25, 26 vermieden wird (Fig. 1).The different design of the compounds of layers of the film, namely sealing seams on the one hand and hot-melt seams on the other hand allows a special manufacturing technology. The running in the longitudinal direction of the web seams are made of hot-melt material. This is preferably applied during the preparation of the film web 34, at least before the folding process. How out Fig. 5 . Fig. 6 As can be seen, a plurality of parallel webs of hot-melt material or of peel-seal material are applied to the film web 34 in the correct position. A special feature is that areas for hot-melt connections, in particular for the connecting seam 27 and for the intermediate seam 31, apply as strip sections or material sections. Hot-melt sections 72 are associated with seam 27. Material sections 74 belong to the intermediate seam 31. The hot-melt sections are dimensioned such that contact with the (later attached) transverse seams produced by thermal sealing, in particular the tab seams 25, 26, is avoided ( Fig. 1 ).

Die mit Abstand aufeinanderfolgenden Materialabschnitte 72 für die Verbindungsnaht 27 sind an einem (oberen) Rand der Folienbahn 34 angeordnet. Gegenüberliegend am (unteren) Folienrand verläuft ein (durchgehender) Peel-Seal-Streifen 73 für die Verschlussnaht 20. Mit Abstand vom (oberen) Rand ist eine weitere Folge von Materialabschnitten 74 aus Hot-Melt-Material vorgesehen für die entsprechend positionierte Zwischennaht 31. Parallel hierzu verläuft ein weiterer Streifen aus mit Abstand voneinander angeordneten Materialabschnitten 75, die mit den Materialabschnitten 74 - nach Faltung der Bahnschenkel 44, 45 - die zusammenwirkenden Materialabschnitte für die Zwischennaht 31 bilden.The spaced-apart material sections 72 for the connecting seam 27 are arranged on an (upper) edge of the film web 34. Opposite the (lower) film edge runs a (continuous) peel-seal strip 73 for the closing seam 20. At a distance from the (upper) edge, a further sequence of material sections 74 of hot-melt material is provided for the correspondingly positioned intermediate seam 31. Parallel thereto, another strip of material portions 75 arranged at a distance from one another runs, which forms the cooperating material sections for the intermediate seam 31 with the material sections 74-after folding of the web legs 44, 45.

Eine weitere Folge von im Abstand angeordneten Materialabschnitten 76 - wiederum aus Hot-Melt-Material - ist den Materialabschnitten 72 zugeordnet. Aufgrund entsprechender Faltung bilden die Abschnitte 72 und 76 die Verbindungsnaht 27. Entsprechend ist ein weiterer Peel-Seal-Streifen 77 für die Verschlussnaht 20 positioniert.Another sequence of spaced-apart material sections 76 - again of hot-melt material - is assigned to the material sections 72. As a result of corresponding folding, the sections 72 and 76 form the connecting seam 27. Correspondingly, a further peel-seal strip 77 for the closing seam 20 is positioned.

Die einander zugeordneten Streifen des aufgetragenen Materials kommen nach Falten der Bahnschenkel 44, 45 zur Überdeckung. Im Bereich der Siegelstation 37 werden die Nähte bzw. Verbindungen 27 und 31 hergestellt. Eine Besonderheit besteht darin, dass bei durchgehenden Materialstreifen aufgrund entsprechender Abmessung der Siegelbacken 61 Verbindungen geschaffen werden, die sich nur über einen Teilbereich der Abmessung eines Beutels 10 in Transportrichtung erstrecken. Der (Entlastungs-)Schlitz 32 wird etwa mittig im Bereich der übereinanderliegenden Materialabschnitte 74, 75 angebracht, damit der Schlitz 32 im Bereich der später hergestellten Zwischennaht 31 sich erstreckt.The mutually associated strips of the applied material come after folding the web legs 44, 45 for coverage. In the area of the sealing station 37, the seams or connections 27 and 31 are produced. A special feature is that due to the appropriate dimension of the sealing jaws 61 connections are created in continuous strips of material, which extend only over a partial region of the dimension of a bag 10 in the transport direction. The (relief) slot 32 is mounted approximately centrally in the region of the superimposed material portions 74, 75, so that the slot 32 extends in the region of the later produced intermediate seam 31.

Eine weitere Besonderheit betrifft die Handhabung des Materials der Beutel. Zur Vermeidung von Umlenkungen der Folienbahn 34 nach Abziehen von der Bobine 35 ist diese auf bewegbaren Halterungen gelagert. In Arbeitsstellung ist die Bobine 35 mit einer Mittenöffnung (nicht gezeigt) auf einem Arbeitszapfen 78 gelagert, der vorzugsweise durch Motor 79 angetrieben ist. Bei der Zuführung einer neuen Bobine 35 ist der Arbeitszapfen 78 in eine horizontale Aufnahmestellung bewegt (Fig. 10). Nach Aufschieben der (neuen) Bobine 35 durch horizontale Bewegung wird der Arbeitszapfen 78 samt Bobine 35 aufgerichtet (Fig. 11) in die Arbeitsstellung. Die Folienbahn 34 kann nun in der aufrechten Ebene bei horizontaler Förderrichtung von der Bobine 35 ohne Umlenkung abgezogen werden.Another special feature concerns the handling of the material of the bag. To avoid deflections of the film web 34 after removal from the reel 35 this is mounted on movable brackets. In the working position, the bobbin 35 is mounted with a central opening (not shown) on a working pin 78, which is preferably driven by motor 79. When feeding a new bobbin 35 of the working pin 78 is moved to a horizontal receiving position ( Fig. 10 ). After sliding the (new) reel 35 by horizontal movement of the working pin 78 is set up with Bobine 35 ( Fig. 11 ) in the working position. The film web 34 can now be deducted in the upright plane in the horizontal conveying direction of the reel 35 without deflection.

Der Arbeitszapfen 78 ist an einem Tragstück 80 gelagert, welches durch ein Schwenkgetriebe 81 bewegbar ist, so dass der Arbeitszapfen 78 zwischen den beiden gezeigten Stellungen bewegbar ist. Das Schwenkgetriebe 81 enthält einen Betätigungszylinder 82 (pneumatisch), der auf einen an dem Tragstück 80 angebrachten Hebel 83 im Sinne einer Schwenkbewegung einwirkt. Dadurch wird das Tragstück 80 mit dem Arbeitszapfen 78 aufgerichtet. Der Motor 79 ist ebenfalls am Tragstück 80 angebracht.The working pin 78 is mounted on a support piece 80 which is movable by a pivoting gear 81, so that the working pin 78 is movable between the two positions shown. The pivoting gear 81 includes an actuating cylinder 82 (pneumatic), which acts on a mounted on the supporting piece 80 lever 83 in the sense of a pivoting movement. As a result, the support piece 80 is erected with the working pin 78. The motor 79 is also attached to the support piece 80.
