- trained bags 10 are obliquely or at an acute angle to the longitudinal extent of the film web 28 directed separating cuts 29 attached.
- the further steps until the completion of the bag 10 correspond to the embodiment according to Fig. 5 to Fig. 8 in an analogous way.
- the closure tab 15 is brought in this example in a first step in the closed position, by folding around the defined by the pocket opening 18 edge 20 in an intermediate fold position ( Fig. 11 ).
- the closure flap 15 or the part flap 23 is folded against the rear wall 14 around one of the beveled edges of the pocket 12, here around the edge defined in the region of the pocket seam 17.
- a triangular formation of the entire bag 10 is given, wherein due to the folding steps given here, the pocket seam 17 is covered by the closure flap 15.
- FIGS. 13 to 15 Another manufacturing method for bags 10 with triangular pockets 12 is shown in FIGS. 13 to 15 shown.
- the production is particularly advantageous for a Feeding the film web 18 in the vertical plane or conveying direction, in this case from top to bottom.
- the film web 28 is prepared so that the bag 12 is in a transverse position, so the pocket opening 18 extends transversely to the film web 28.
- the shape of the pocket 12 chosen in this exemplary embodiment corresponds to that of an isosceles, right-angled triangle.
- the tip 19 is directed downwards.
- the film web 28 which is preferably transported continuously in the downward direction, is provided with inclined separating cuts 29 starting from a free edge, at an acute angle to the (upright) side edge.
- a triangular tab defined by the marginal edge of the film web 28 and the separating cut 29 is detected and positioned as a front wall 13 of the pocket 12 by folding over.
- the pocket seam 17 is attached, which extends in extension of the slanted separating cut 29.
- the filling of the bag 12 can now take place (or after separation of the bag 10 of the film web 28). The separation cut required for this is carried out along the pocket seam 17.
- the total triangular closure flap 15 is folded in the manner described, wherein the last folded triangular part flap 23 is folded around the defined by the pocket seam 17 edge of the pocket 12, so that the seam 17 is covered by the flap 15.
- the total of triangular-shaped bag 10 when the closure flap 15 is closed can be positioned in bundle packs in a spatially advantageous manner ( Fig. 16 ).
- Each two bags 10 are arranged side by side in a transverse plane, so that two equal-length oblique edges, in particular the edges formed in the region of the pocket opening 18, face each other or lie against one another. This results in a total rectangular or square structure.
- Several such pairs of bags 10 are adjacent and to each other, so that a total cuboid bundle pack is formed ( Fig. 16 ).
- the bag 12 is trapezoidal. Lateral boundaries of the pocket 12 are directed at an acute angle to each other. These are, on the one hand, the side edge of the pocket 12 formed by the folding edge 16 and, on the other hand, the edge in the area of the pocket seam 17.
- the trapezoidal shape is chosen here such that the folding edge 16 extends transversely to the edges 20 of the pocket opening 18 and the pocket Pocket seam 17 is directed at an angle to the pocket opening 18.
- the pocket 12 ends in the region of a transverse bottom seam 31.
- the closure surface 15 is also formed on the same construction principle of the bag 10, namely consists of two triangular part flaps 22, 23. Overall, the closure flap 15 is formed as a continuation of the rear wall 14, but arranged laterally, namely in extension over the pocket seam 17 addition.
- the locking tab 15 is a crooked rectangle or square.
- the part flap 22 is folded against the (trapezoidal) front wall 13 ( Fig. 21 ). Due to the different geometrical shapes of the pocket 12 on the one hand and the closure flap 15 or the partial flaps 22, 23 on the other hand, only a portion of the front wall 13 is covered by the closure flap 15, namely by the part flap 22.
- the (triangular) part flap 23 is folded against the back of the bag 12, namely to rest on the rear wall 14. Again, a complete coverage of the rear wall 14 due to the different geometric shapes is not given. However, the pocket opening 18 is covered over the full length by the closing tab 15, namely by the folding edge 26.
- a (in this case unfolded) blank 32 is separated for each bag 10.
- the width of the blank 32 or the height of the bag 10 or the pocket 12 corresponds to the width of the film web 28.
- the blank 32 is trapezoidal in overall shape with convergent, directed transversely to the film web 28 blank edges 33, 34.
- the blank 32 is sized so that successive areas for the trapezoidal pocket 12 with the pocket walls 13, 14 and then the existing of the two part flaps 22, 23 closing tab 15 are defined here by imaginary, each represented by dashed lines fold lines. Every second of the film web 28 cut blank 32 is turned by 180 °, so that the in FIGS. 18 and 19 given uniform relative position is given.
- the bag 12 is formed ( Fig. 19 ) by folding over a portion of the blank 32 along the folded edge 16 so that surface areas for forming the front wall 13 and the rear wall 14 lie on each other.
- the obliquely oriented pocket seam 17 and the bottom seam 31 extending in the longitudinal direction of the blank 32 can now be produced.
- the pocket opening 18 is located on a free side edge of the blank 32, which corresponds to one or the other longitudinal edge of the film web 28.
- the bag is now made so far that the tobacco portion 11 can be inserted into the pocket 12 ( Fig. 20 ). Thereafter, the folding steps described are performed.
- a closing seam 27 can also be attached here.
- the pocket opening 18 is covered in full length by the closure tab 15 in the region of the fold edge or fold line 26.
- the film web 28 for producing the pouches 10 is dimensioned in width so that two pouches 10 are produced side by side, possibly with mutual interleaving, essentially simultaneously.
- Another special feature is that the film web 28 formed with a corresponding width is a single-layer carrier web and that in the region of the double-walled design of the bag 10, ie in the region of the pocket 12, further film material is supplied or processed.
- a (continuous) film strip 35 is applied to the film web 28, in particular centrally. This is connected in the formation of the bag 10 with corresponding portions of the film web 28.
- the film strip 35 consisting of preferably the same film serves in the present case to form a part of the pockets 12, in particular the pocket front wall 13.
- the film strip 35 lying on the film web 18 corresponds in width to a corresponding dimension of the pocket 12.
- Sealing seams form the connection
- a transverse pocket seam 17 and additionally a diagonal side seam 36 is produced by thermal sealing.
- the triangular pocket 12 is therefore bounded by two sealing seams 17, 36 arranged in a V-shape.
- the locking tab 15 as (on both sides) edge strip of the film web 28 is formed in the manner described rectangular or square.
- This method can also be produced in an analogous manner for the production of (tobacco) bags with conventional, namely rectangular pockets, the pockets being formed by a bottom seam running in the longitudinal direction of the film web or film strip 35 and by transverse pocket seams.
- V-shaped double seams 37, 38 in the region of the continuous film web 28 with strips 35 are preferably produced at the same time. These are designed such that they form pocket seams 17 of adjacent bags 10 next to one another on the one hand and side seams 36 of two simultaneously produced bags 10 on the other hand.
- a transverse separating cut across the full width of the film web 28 and through an obliquely directed separating cut centrally in the area of the double seam 38 the two bags 10 are produced simultaneously and separated from the film web 28.
- the centrally severed double seam 37 forms one of the pocket seams 17 of the subsequently produced pair of bags 10 in the region of a transverse edge of the film web 28.
- the principle of performance increase by means of film web 28 corresponding to greater width is also in the example according to Fig. 26, Fig. 27 realized. In this example, it is about the preferably simultaneous production of transverse to the film web 28 adjacent bags 10. These are formed here in a conventional manner, namely with a rectangular pocket 12 and two side pocket seams 39, 40.
- the pockets 12 of the adjacent Beuel 10 are formed by continuous folding of edge limbs 41, 42. These form a continuous double-layer edge strip on both sides of the film web 28. From the edge legs 41, 42 are respectively the front walls 13 of the pockets 12th
- the width of the film web 28 is selected so that facing each other, namely between the two edge legs 41, 42, closure tabs 15 are formed for each bag 10. These can be formed as a simple closure tab or - as in the illustrated embodiment - as a wrapper. In the present case, the opposing bags 10 are arranged offset from one another. transverse Separating sections of the film web 28 are accordingly offset in the longitudinal direction of the same.
- the closure tabs 15 are provided with a tongue 43 with curved edges as a closure region of the part-flap 23 resting against the rear wall 14 (FIG. Fig. 27 ).
- the contour is continuously created by a correspondingly shaped wave-shaped, central dividing line 44 of the film web 28.
- the pocket seams 39, 40 are produced as double-wide seams in the region of the film web 28 and severed centrally by the transverse separating cuts to form the pocket seams 39, 40.

Die dargestellten Beutel 10 bestehen aus einer thermisch siegelbaren Folie. Für einen Beutelinhalt, insbesondere eine Tabakportion 11, bildet der Beutel 11 eine Tasche 12 mit einer frontseitigen Taschenwand, nämlich einer Vorderwand 13 und einer entsprechenden Rückwand 14. Die Rückwand 14 ist mit einem Fortsatz der Folie versehen unter Bildung einer Verschlusslasche 15, die vorliegend als Wickellasche ausgebildet ist und in Schließstellung an der Vorderwand 13 einerseits und der Rückwand 14 andererseits anliegt.The illustrated
Eine Besonderheit ist die Form der Tasche 12. Diese ist bei den bevorzugten Ausführungsbeispielen dreieckförmig ausgebildet, nämlich mit dreieckiger Vorderwand 13 und entsprechender Rückwand 14. Die vorzugsweise gleichgroßen Taschenwände 13, 14 sind entlang einer schräggerichteten Faltkante 16 und gegenüberliegend durch eine ebenfalls schräggerichtete Verbindungsnaht, nämlich Taschennaht 17 mittels thermischer Siegelung (oder durch Klebung) miteinander verbunden. Die dreieckförmige Tasche 12 erfordert vorzugsweise nur eine Siegelnaht zur Verbindung der Taschenwände 13, 14. Eine Taschenöffnung 18 ist gegenüberliegend einer durch die konvergierenden Taschenränder gebildeten Spitze 19 angeordnet.A peculiarity is the shape of the
Die Verschlusslasche 15 ist vorteilhafter Weise so ausgebildet, dass sie in Schließstellung mindestens die Vorderwand 13, zweckmäßigerweise aber auch die Rückwand 14 der Tasche 12 mindestens teilweise abdeckt. Bei dem besonderen Ausführungsbeispiel gemäß
Die Teillasche 23 ist vorzugsweise an der Rückwand 14 lösbar fixiert, vorliegend durch eine Klebe- oder Klettverbindung. Entsprechende Verbindungsstücke 24, 25 sind an korrespondierenden Eckbereichen von Tasche 12 und Verschlusslasche 15 angebracht, nämlich in einem Eckbereich der Rückwand 14 einerseits und einem zugeordneten Eckbereich der Verschlusslasche 15 bzw. der Teillasche 23 andererseits.The
Die Kontur des Beuteln 10 bzw. der Tasche 12 kann bei dreieckförmiger Gestaltung unterschiedlich sein, beispielsweise als rechtwinkliges, gleichschenkliges Dreieck, bei dem die Faltkante 16 die Hypotenuse bildet. Der Beutel 10 bzw. die Tasche 12 kann alternativ als gleichschenkliges Dreieck ausgebildet sein (
Eine Besonderheit ist die Herstellung von (Tabak-)Beuteln 10 mit dreieckiger Tasche 12. Eine Materialbahn, insbesondere eine Folienbahn 28 ist in der Breite so ausgebildet, dass sie der Abmessung der Tasche 12 entlang der Taschennaht 17 zuzüglich der Breite bzw. Querabmessung der Verschlusslasche 15 entspricht. Während des Transports der Folienbahn 28 werden Trennschnitte 29 angebracht, die sich von einem freien Rand der Folienbahn 28 etwa bis zur Mitte der Bahn erstrecken, bei dem Ausführungsbeispiel gemäß
In einem weiteren Arbeitsschritt wird die Tasche 12 (als Teil der Folienbahn 28) gebildet, und zwar durch Umfalten einer Taschenwand, insbesondere der Vorderwand 13 entlang der Faltkante 16 bis zur Anlage an der Rückwand 14. Sodann werden die (quergerichteten) freien Ränder der Taschenwände 13, 14 durch Anbringen der Taschennaht 17 (quer zur Längserstreckung der Folienbahn 28) miteinander verbunden. Die Tasche 12 ist damit im Prinzip fertiggestellt. Es kann jetzt die Tabakportion 11 eingefüllt werden. Alternativ wird die Befüllung nach Abtrennen des Beutels 10 von der Folienbahn 28 durchgeführt. Hierzu wird ein Trennschnitt in (geradliniger) Verlängerung des Trennschnitts 29 durchgeführt, wodurch die dem jeweiligen Beutel 10 zugeordnete Verschlusslasche 15 von der Folienbahn 28 abgetrennt wird (
Bei dem Ausführungsbeispiel der
Bei der Herstellung von entsprechend
Ein anderes Herstellungsverfahren für Beutel 10 mit dreieckförmigen Taschen 12 ist in
Bei der Fertigung wird die vorzugsweise kontinuierlich in Abwärtsrichtung transportierte Folienbahn 28 mit schräggerichteten Trennschnitten 29 von einem freien Rand ausgehend versehen, unter einem spitzen Winkel zur (aufrechten) Seitenkante. In einem ersten Faltschritt wird eine durch die Randkante der Folienbahn 28 und den Trennschnitt 29 definierte dreieckige Lasche erfasst und durch Umfalten als Vorderwand 13 der Tasche 12 positioniert. Danach wird die Taschennaht 17 angebracht, die sich in Verlängerung des schräggerichteten Trennschnitts 29 erstreckt. Die Befüllung der Tasche 12 kann nun erfolgen (oder nach Abtrennen des Beutels 10 von der Folienbahn 28). Der hierfür erforderliche Trennschnitt wird entlang der Taschennaht 17 ausgeführt.During production, the
Die insgesamt dreieckförmige Verschlusslasche 15 wird in der beschriebenen Weise gefaltet, wobei die zuletzt gefaltete dreieckförmige Teillasche 23 um die durch die Taschennaht 17 definierte Kante der Tasche 12 gefaltet wird, sodass die Naht 17 durch die Lasche 15 verdeckt ist.The total
Die bei geschlossener Verschlusslasche 15 insgesamt dreieckförmig ausgebildeten Beutel 10 sind in einer räumlich vorteilhaften Weise in Gebindepackungen positionierbar (
Ein weiteres Ausführungsbeispiel eines (Tabak-)Beutels 10 auf der Grundlage von konvergierenden, also unter einem Winkel zueinander gerichteten Kanten der Tasche 12, ist in
Die Verschlusslache 15 ist ebenfalls nach dem gleichen Konstruktionsprinzip der Beutel 10 ausgebildet, besteht nämlich aus zwei dreieckigen Teillaschen 22, 23. Insgesamt ist die Verschlusslasche 15 als Fortsetzung der Rückwand 14 ausgebildet, jedoch seitlich angeordnet, nämlich in Verlängerung über die Taschennaht 17 hinaus. Die Verschlusslasche 15 ist ein schiefes Rechteck bzw. Quadrat. In einem ersten Faltschritt wird die Teillasche 22 gegen die (trapezförmige) Vorderwand 13 umgefaltet (
Bei der Fertigung von so oder ähnlich ausgebildeten Beuteln wird analog zu den vorstehenden Beispielen verfahren. Von einer fortlaufenden Folienbahn 28 wird ein (vorliegend ungefalteter) Zuschnitt 32 für jeweils einen Beutel 10 abgetrennt. Die Breite des Zuschnitts 32 bzw. die Höhe des Beutels 10 respektive der Tasche 12 entspricht der Breite der Folienbahn 28. Der Zuschnitt 32 ist insgesamt trapezförmig ausgebildet mit konvergierenden, quer zur Folienbahn 28 gerichteten Zuschnitträndern 33, 34. Der Zuschnitt 32 ist so bemessen, dass aufeinanderfolgend Bereiche für die trapezförmige Tasche 12 mit den Taschenwänden 13, 14 und anschließend die aus den beiden Teillaschen 22, 23 bestehende Verschlusslasche 15 definiert sind, hier durch gedachte, jeweils durch gestrichelte Linien dargestellte Faltlinien. Jeder zweite von der Folienbahn 28 abgetrennte Zuschnitt 32 wird um 180° gewendet, sodass die in
In einem ersten Falt- und Fertigungsschritt wird die Tasche 12 gebildet (
Ein leistungsfähiges Fertigungsprinzip für Beutel 10 der vorstehend beschriebenen Ausführungen ergibt sich aus
Bei der Fertigung von zwei nebeneinanderliegenden Beuteln 10 werden vorzugsweise gleichzeitig V-förmige Doppelnähte 37, 38 im Bereich der fortlaufenden Folienbahn 28 mit Streifen 35 hergestellt. Diese sind so ausgebildet, dass sie nebeneinanderliegend einerseits Taschennähte 17 benachbarter Beutel 10 und andererseits nebeneinanderliegende Seitennähte 36 von zwei gleichzeitig gefertigten Beuteln 10 bilden. Durch einen quergerichteten Trennschnitt über die volle Breite der Folienbahn 28 und durch einen schräggerichteten Trennschnitt mittig im Bereich der Doppelnaht 38 werden die beiden Beutel 10 gleichzeitig hergestellt und von der Folienbahn 28 abgetrennt. Die mittig durchtrennte Doppelnaht 37 bildet eine der Taschennähte 17 des nachfolgend hergestellten Paares von Beuteln 10 im Bereich eines Querrandes der Folienbahn 28.In the production of two juxtaposed
Das Prinzip der Leistungssteigerung mittels Folienbahn 28 entsprechend größerer Breite ist auch bei dem Beispiel gemäß
Die Breite der Folienbahn 28 ist so gewählt, dass einander zugekehrt, nämlich zwischen den beiden Randschenkeln 41, 42, Verschlusslaschen 15 für jeden Beutel 10 gebildet werden. Diese können als einfache Verschlusslasche oder - wie beim dargestellten Ausführungsbeispiel - als Wickellasche ausgebildet werden. Vorliegend sind die einander gegenüberliegenden Beutel 10 versetzt zueinander angeordnet. Quergerichtete Trennschnitte der Folienbahn 28 sind demnach in Längsrichtung derselben versetzt zueinander angeordnet. Die Verschlusslaschen 15 sind mit einer Zunge 43 mit geschwungenen Rändern versehen als Verschlussbereich der an der Rückwand 14 anliegenden Teillasche 23 (
