The primary concern is the production, filling and completion of bags 10 made of thin packaging material, in particular (thermally sealable) film. The bag 10 consists of a one-piece, here rectangular, elongated blank, which, due to the folding of a leg, forms a pocket 11 for the contents of the package with the front pocket 12 and the rear pocket 13. These adjoining regions of the blank are connected to one another by thermal welding or gluing through side seams 14, 15. An opening 16 is used to fill the bag 11 and to remove the contents. The pocket rear wall 13 is extended beyond the opening 16 and forms a closure flap or a winding flap 17. This is folded around the pocket 11 when the pocket 11 is filled and possibly closed by closing strips in the region of the opening 16, such that an end region of the winding flap 17 rests against the pocket rear wall 13 and is connected to it.

The bag 10 is provided with applications or blanks fastened by gluing, optionally also by thermal sealing (welding). In the present example it is used as a closure of the bag 10 a tape 18 on the free edge of the winding tab 17 - approximately in the middle - attached. The strip-shaped closure means has a coating of permanent adhesive on one side and an adhesive-free grip tab 19 at the free end region.

Furthermore, in this example, a print carrier or a (multiply folded) coupon 20 is attached to the bag 10. It is an advertising or information carrier. The coupon 20 is fixed to the inside of the winding tab 17 by gluing, approximately in the middle.

Furthermore, a holding element for additions is attached to the bag 10, specifically a rectangular holding piece, namely a sticker 21. This has an adhesive surface on both sides, namely for fastening to the bag 10 and for attaching additions, in particular a packet with cigarette paper. The sticker 21 is attached here to the outside of the pocket front wall 12.

A special feature is that the above-mentioned applications 18, 20, 21 are attached to the bag 10 before it is filled and closed. The finished, but unfilled, bags 10 are formed by separating them from a continuous material or film web 22. During continuous transport in a folding station 23, this is provided with a longitudinal fold, namely with a continuous web leg 24 which, in the bag 10, the pocket front wall 12 forms. Thereafter, transverse seams 25 are applied in a sealing station 26 in the area of the folded film web 22. The connecting seams 25 have twice the width of the side seams 14, 15. In a subsequent separating station 27, the bags 10 are made according to Fig. 1 separated from the film web 22 by a transverse cut, in the middle in the region of a connecting seam 25, so that this is divided into two adjacent side seams 14, 15. The separated bags 10 are fed to a transfer station 28 and transferred to a filling and closing station 29 in the area thereof.

The separate blanks 18, 20, 21 are attached to the film web 22 in the pouch-like position. A transfer station 30 is preferably positioned between the sealing station 26 and the separating station 27. The blanks, at least the tape 18, are accordingly attached to the film web 22 after the pockets 11 are defined by the connecting seams 25.

A device for producing, filling and closing the bags 10 is characterized by a compact grouping of units. The (unfolded) film web 22 is pulled off a bobbin 31 with a horizontal axis of rotation and fed to the folding station 23 via a compensating pendulum 32. The web leg 24 is formed by a stationary, essentially triangular folding element 33 (folding switch) during continuous transport of the film web 20. At the same time, the film web 22 is deflected by 90 ° in a main conveying direction. The compensating pendulum 32 serves to compensate for different rotational speeds of the bobbin 31 or to generate a constant, continuous conveying speed in the area of the folding station 23.

The film web 22 prepared in this way is passed over deflection and drive rollers through a sealing unit 34 for the attachment of the connecting seams 25. The sealing unit 34 is arranged upright. The film web 22 is inserted into the sealing unit 34 at an upper end and, after the connecting seams 25 have been attached, is led out of the sealing unit 34 at the lower end by means of cross-directionally and transversely movable sealing or welding members. The film web 22 is then fed up again and passed through a further compensation pendulum 35. In the area of the sealing unit 34, the web 22 is driven in cycles. The following stations are also geared towards the intermittent conveying of the film web 22, but with conveying cycles that differ from the area of the sealing unit 34. These different movements are compensated for by the compensating pendulum 35.

The transmission station 30 is equipped with a transmission unit, for example a tape unit 36, of which an advantageous embodiment is shown in FIG Fig. 4 is shown. The attachment of one or more of the blanks 18, 20, 21 takes place in the region of a deflection of the film web 22, namely on the circumference of a transfer roller 37. The film web 22 is guided along an obliquely downward conveying path via a deflection roller 38 and on the circumference of the transfer roller 37 created. A wrap angle is more than half the circumference. In connection with the deflection roller 38, an S-shaped movement path of the film web 22 results.

The transfer roller 37 is in the example according to Fig. 4 assigned to the tape unit 36. The tapes 18 are positioned on a carrier web 40, specifically with the longitudinal extent of the tape 18 transverse to the strip-shaped carrier web 40. This is pulled off a roll and fed to the circumference of the transfer roller 37 via deflection rollers. In the area of a sharp-edged deflection 39 of the carrier web 40, a tape 18 is peeled off from the carrier web 40 by peeling and taken over by a pressure roller 42 for transmission to the bag 10 or to the film web 22 on the circumference of the transfer roller 37. How out Fig. 6 as can be seen, the procedure is preferably such that the carrier web 40 is guided around a free edge of a deflection wall 41, that is to say around a relatively sharp edge. The tape 18 which is released in the process is transferred to the film web 22 by a pressure member or by the pressure roller 42, in a corresponding position accordingly Fig. 1 , ie in the region of a free edge of the winding tab 17 with the projection shown. The exact positioning of the tape 18 is ensured by an optoelectronic scanning element 43 controlled by means of print marks on the film web 22. The transfer roller 37 is also set up as a drive roller for the film web 22, preferably with a servo drive. The film web 22 is positioned in the region of the cutting unit in such a way that the side with the web leg 24 lies against the transfer roller 37. The side of the tape 18 provided with glue therefore faces the transfer roller 37.

For the error-free transfer of the tape 18 to the film web 22, the transfer roller 38 is extended in the axial dimension beyond the area of the bag 10 or the winding tab 17 and is formed with a special edge area 44 which is used to receive or apply the protruding tape already 18. This comes to rest with the free adhesive side on the edge area 44 which has a low holding force and which is provided with pointed or sharp-edged projections 45, in particular ribs running all around. The adhesive surface of the tape 18 is easily detachable at the tips. The non-stick grip tab 19 lies against a cylindrical edge surface of the transfer roller 37 and is held here by radial suction bores 46, that is to say by negative pressure.

The opposing pressure roller 42 is also provided with holding means for the tape 18 until it is transferred to the transfer roller 37, namely with a plurality of radial suction bores 47 connected to a vacuum source.

The film web 22 provided with the tapes 18 (or other cuts) is transported further in the lower region of the transfer roller 37 in the horizontal plane and is fed to a separating member 48 of the separating station 27. The film web 22 is placed on a conveyor, in particular on an intermediate conveyor 48 designed as a suction belt. This leads the film web 22 directly to a parting plane. The intermediate conveyor 48 is designed in a special way ( Fig. 9 ). It consists of a suction box 49 below an upper or conveying run of the intermediate conveyor 48. The suction box 49 is connected to a vacuum source. An upper wall, against which the conveying strand of the intermediate conveyor 48 rests, is provided with a plurality of suction holes 50. The intermediate conveyor 48 is either air permeable overall or provided with a plurality of distributed suction holes which correspond to the suction holes 50 of the suction box 49. The film web 22 is accordingly removed from the circumference of the transfer roller 37 by the intermediate conveyor 48 due to the suction air and is fed in a horizontal plane to the subsequent separating unit.

In order to ensure reliable guidance of the tape 18, a strip conveyor connects to the transfer roller 37 above the take-over conveyor 48 and is effective in the area of the grip tab 19 of the tape 18. It is a round belt 51 which is attached to the handle tab 19 with a lower conveyor strand. The conveyor or round belt 51 extends from an area immediately adjacent to the transfer roller 37 to the area of a further conveyor for the separated bags 10, namely up to above a bag conveyor 62. The round belt 51 runs through the separation station 27 in the lateral area .

In addition to the round belt 51, a support member for the film web 22 is fixedly mounted above the take-over conveyor 48, namely a guide piece 52, which ends in a wedge shape on the side facing the transfer roller 37 and extends exactly opposite to the parting plane. The flat or plate-shaped guide piece 52 prevents warping of the film web 22 after leaving the transfer roller 37.

In the area of the separating station 27, a separating element is effective in cycles, which performs a separating cut approximately centrally in the area of the connecting seam 25 across the full width of the film web 22. The separating member consists of a separating knife 53 which is pivotally mounted outside the area of the film web 22. The separating knife 23 accordingly carries out a separating cut as a pivoting movement carried out in an upright plane. The separating knife is pivotable about a pivot bearing 54, which is preferably slidably mounted on a support wall 55 of the machine frame. An actuating gear causes the coordinated up and down movement of the cutting knife 53. For this purpose an actuating arm 56 with a sensing roller can be actuated by a rotating cam plate 57. Cutting knife 53 and actuating arm 56 act as a two-armed lever. The movement amplitude of the cutting knife 53 is dimensioned such that a full cutting cut is carried out. A counter knife 58 interacts with the separating knife 53. This is designed as a fixed, cross-directional cutting piece. The separating knife 53 and counter knife 58 together result in a scissor-like cutting process due to the pivoting movement of the separating knife 53. The counter knife 58 is arranged below the plane of the film web 22.

The separating knife 53 or the pivot bearing 54 is slidably attached to the support wall 55 in order to adjust the cutting or separating plane. This enables the production of bags 10 of different widths. The counter knife 58 is also moved as a unit. For this purpose, the pivot bearing 54 is attached to a carrier 60 which is mounted such that it can be displaced, in particular on the supporting wall 55. The separating knife 53 or the leg bearing 54 is under the pressure of a spring 61 in the direction of the counter knife 58, so that it is always precise Cut is guaranteed.

The separated bags (including tape 18) are taken over by a connection conveyor, namely the bag conveyor 62. This transports the bags 10 at a distance from one another into the area of the transfer station 28. In this area, the bags 10 are picked up one after the other and sent to a filling and closing unit transferred, namely to a bag turret 63. The device is designed such that a plurality, in the present case four bags 10, are presented on the bag conveyor 62, captured and transferred to the bag turret 63. The filled and closed bags are placed on a conveyor 64 and transported away.

For the displacement of the cutting or parting plane in the parting station 27, the bag conveyor 62 or an initial region facing the parting station 27 can also be adjusted. The bag conveyor 62 is designed as a suction conveyor for adequately fixing the bags 10 on an upper run 80. A suction box 81 is arranged beneath the same for transferring negative pressure to the upper run 80. The suction box 81 is designed telescopically for moving the receiving end of the bag conveyor 62, namely with a telescopic box 82. This extends up to an upper deflection roller 83 for the upper run 80. The relative position always remains unchanged, since the telescopic box 82 enters the suction box 81 more or less far. The telescopic box 82 is also designed as a vacuum source for the upper run 80 so that the bags 10 are secured up to the deflection roller 83. Furthermore, the belt of the bag conveyor 62 is guided around a compensating roller 84 which, in the present exemplary embodiment, is connected to the telescopic box 82, but in any case is movable with it. As a result, the tension in the belt of the bag conveyor 62 is maintained even when the receiving end is displaced. A further deflection roller 85 is provided below the compensating roller, which guides the belt into the lower run or receives it from the latter.

The transfer station 30 can be designed in such a way that not only a closure means (tape 18) but also further blanks are transferred to the bags 10 or the prepared film web 22. In the embodiment according to Fig. 5 a tape 18 is applied to the film web 22 by a modified transfer unit 36. In addition, it is provided that two further blanks are applied, for example a sticker 21 and a coupon 20 or folding coupon.

In this application too, the transfer unit 36 is assigned to a transfer roller 37, on the circumference of which the film web 22 prepared in the manner described is transported. The tapes 18 are separated from a continuous tape web 65 by transverse separating cuts and are applied to the film web 22 in a precisely positioned manner by a feed roller 66, as in connection with FIG Fig. 4 , Fig. 6 described. The tape web 65 is pulled off a roll 67. A cutting mechanism 68, which is only shown schematically, divides transversely directed tapes 18 from the correspondingly designed tape web 65. This is provided on one side (above) with permanent adhesive and on the edge with a continuous non-sticky strip to form the grip tab 19.

A coupon unit 69 and a sticker unit 70 are arranged upstream of the transmission unit 36 in the transport direction. The units 69 and / or 70 are positioned in the region of a horizontal path section 71, above the transmission unit 36. The units 69 and 70 are largely identical. The coupons 20 on the one hand and the stickers 21 on the other hand are each arranged on a carrier film 72. This is drawn off from a roll 73. Analogous to the embodiment according to Fig. 4 , Fig. 6 the carrier web 72 is guided over deflection rollers to a transfer point 74. In this region, the carrier web 72 is deflected with sharp edges, specifically in a region immediately above the film web 22. In the region of a deflection wall 41, the blank 20, 21 in question is removed from the carrier web 72 peeled off and exposed. A pressing member, namely a plunger 75 that can be moved up and down, presses the relevant blank onto the film web 22 with a glue surface facing downward. The empty carrier web 72 is wound up to form an empty spool 76.

The film web 22 is transported in the region of the units 69, 70 in such a way that the pocket front wall 12 or the web leg 24 is directed upwards, that is to say is exposed. In the exemplary arrangement of the blanks 20, 21 on the bag ( Fig. 1 ), the units 69, 70 are arranged offset to one another in the transverse direction of the film web 22, the coupon unit 69 being aligned approximately centrally to the web area of the winding tab 17 and the sticker unit 70 approximately centrally to the web leg 24.

The units 69, 70 work with a cyclical preference of the film web 22. As an alternative to the embodiment according to Fig. 4 , Fig. 6 , The transfer unit 36 for the tape 18 can also be positioned in the region of a horizontal web section 71. In such a variant, however, the film web 22 must be turned in front of a tape unit 36 so that the tape 18 can be attached to the film web 22 in the correct position. Analogously even when the tape unit 36 is designed Fig. 5 the tape can be transferred to the transfer roller 37 by means of a stamp, corresponding to the units 69, 70. In this variant, the film web 22 must stand still during the transfer of the tape.

In general, with regard to the movement characteristics of the film web 22, it is transported in the case of a tape unit 36 with a rotating transmission element during the transmission of the tape 18, but is otherwise stopped intermittently in order to carry out the separating cut in the region of the separating station 27.

Fig. 11 shows a possible variant of the transmission station 30 according to the embodiment of FIG Fig. 4 , 6 . The separate guiding and conveying member for the laterally projecting leg of the tape 18, in particular the round belt 51, is in the embodiment of the Fig. 11 united with the transfer roller 37. This is in the edge area 44 ( Fig. 12 ) provided with a guide groove 77 in which the round belt 51 runs and is guided. The groove 77 has an approximately semicircular cross section and is located directly on the edge of the transfer roller 37 or in the region of the grip tab 19. In addition, the projections 45 already described are formed, on the edges of which the exposed area of the tape 18 coated with adhesive rests. In this exemplary embodiment, the round belt 51 wraps around the transfer roller 37 almost completely. A deflection roller 78 leads an upper run back in the horizontal running direction to a further deflection roller 79, which lies directly above the plane of movement of the bags 10 and is aligned with the circumference of the transfer roller 37.
