Priority is given to the manufacture, 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 forms a pocket 11 due to folding of a leg for the package contents with pocket front wall 12 and pocket rear wall 13. These adjacent portions of the blank are joined together by thermal welding or gluing , By 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 wrap flap 17. When the pocket 11 is filled and possibly closed in the area of the opening 16, this flap is folded around it such that an end area of the wrap flap 17 abuts the pocket rear wall 13 and is connected thereto.

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

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 retaining member for gifts on the bag 10 is attached, namely a rectangular holding piece, namely a sticker 21. This has on both sides of an adhesive surface, namely for attachment to the bag 10 and for attaching gifts, especially a packet of cigarette paper. The sticker 21 is here attached to the outside of the pocket front wall 12.

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

The separate blanks 18, 20, 21 are attached to the film web 22 in the bag position. Preferably, a transfer station 30 is positioned between the sealing station 26 and the separation station 27. The blanks, at least the tape 18, are thus attached to the film web 22 after the pockets 11 are defined by the seams 25.

An apparatus for making, filling and sealing the bags 10 is characterized by a compact grouping of aggregates. The (unfolded) film web 22 is withdrawn from a reel 31 with a horizontal axis of rotation and fed to the folding station 23 via a compensating shuttle 32. By a stationary, substantially triangular folding member 33 (Faltweiche) of the web leg 24 during continuous transport of the film web 20 is formed. 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 region of the folding station 23.

The thus prepared film web 22 is passed over deflecting and drive rollers through a sealing unit 34 for attaching the connecting seams 25. The sealing unit 34 is arranged upright. The film web 22 is inserted at an upper end in the sealing unit 34 and led out after attaching the connecting seams 25 by means of transverse and transversely movable sealing or welding organs at the lower end of the sealing unit 34. The film web 22 is then brought up again and passed through a further compensating pendulum 35. In the area of the sealing unit 34, the web 22 is cyclically driven. The subsequent stations are also aligned to cyclically conveying the film web 22, but with deviating from the area of the sealing unit 34 conveying acts. These different movements are compensated by the compensation pendulum 35.

The transfer station 30 is equipped with a transfer unit, for example a tape unit 36, of which an advantageous embodiment 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 downwardly directed conveying path via a guide roller 38 and to the periphery of the transfer roller 37th created. A wrap angle is more than half the circumference. In conjunction with the deflection roller 38 results in an S-shaped movement path of the film web 22nd

The transfer roller 37 is in the example according to Fig. 4 associated with the tape unit 36. The tapes 18 are positioned on a carrier web 40, with the longitudinal extent of the tape 18 transversely to the strip-shaped carrier web 40. This is withdrawn from a roll and fed via pulleys to the circumference of the transfer roller 37. In the region of a sharp-edged deflection 39 of the carrier web 40, a tape 18 is removed from the carrier web 40 by peeling (exfoliation) and taken over by a pressure roller 42 for transfer to the bag 10 and to the film web 22 on the circumference of the transfer roller 37. How out Fig. 6 can be seen, is preferably moved so that the carrier web 40 is guided around a free edge of a Umlenkwandung 41, ie a relatively sharp edge. The thereby released tape 18 is transferred by a pressing member or by the pressure roller 42 on the film web 22, in a relative position accordingly Fig. 1 , So in the region of a free edge of the winding tab 17 with the supernatant shown. The exact positioning of the tape 18 is controlled by an opto-electronic scanning device 43 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 blank assembly such that the side with the web leg 24 rests against the transfer roller 37. The provided with glue side of the tape 18 is thus facing the transfer roller 37.

For error-free transmission of the tape 18 to the film web 22, the transfer roller 38 is extended in the axial dimension over the region of the bag 10 and the winding tab 17 also and formed with a special edge portion 44, which for receiving or conditioning of the protruding Already the tape 18. This comes with the free adhesive side of the low holding force having edge portion 44 to the system, which is provided with pointed or sharp-edged expiring projections 45, in particular around running ribs. At the tips of the adhesive surface of the tape 18 is easily detachable. The tack-free grip tab 19 bears against a cylindrical edge surface of the transfer roller 37 and is held here by radial suction holes 46, ie by negative pressure.

The opposite pressure roller 42 is also provided with holding means for the tape 18 to the transfer to the transfer roller 37, namely with a plurality of connected to a vacuum source radial suction holes 47th

The provided with the tapes 18 (or other blanks) film web 22 is further transported in the lower region of the transfer roller 37 in a horizontal plane and fed to a separating member 48 of the separation station 27. The film web 22 is deposited on a conveyor, in particular on a conveyor belt designed as an intermediate conveyor 48. This leads the film web 22 to 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. A top wall, against which the conveying run of the intermediate conveyor 48 rests, is provided with a plurality of suction holes 50. The intermediate conveyor 48 is either air-permeable as a whole 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 therefore removed by the intermediate conveyor 48 due to the suction air from the periphery of the transfer roller 37 and fixed in the horizontal plane to the following separation unit.

In order to ensure a secure guidance of the tape 18, a strip conveyor adjoins the transfer roller 37 above the transfer conveyor 48, which is effective in the region of the gripping tab 19 of the tape 18. It is a round belt 51, the 19 receives with a lower conveyor to the grip tab system. The conveyor or round belt 51 extends from an area immediately adjacent to the transfer roller 37 into the area of a further conveyor for the separated bags 10, namely above a bag conveyor 62. The round belt 51 runs - in the lateral area - through the separation station 27 therethrough ,

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

In the region of the separation station 27, a separating member is cyclically effective, which performs a separating cut approximately centrally in the region 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 region of the film web 22. The separating knife 23 thus performs a separating cut as performed in an upright plane pivoting movement. The separating knife is pivotable about a pivot bearing 54, which is preferably mounted displaceably on a support wall 55 of the machine frame. An actuating gear causes the coordinated up and down movement of the separating blade 53. For this purpose, an actuating arm 56 with a follower roller by a rotating cam 57 can be actuated. Disconnecting blade 53 and actuator arm 56 act as a two-armed lever. The amplitude of movement of the separating knife 53 is dimensioned such that a full separating cut is carried out. With the separating knife 53 a counter knife 58 cooperates. This is designed as a fixed, transverse cutting piece. Cutting knife 53 and counter knife 58 together result in a scissor-like cutting operation by the pivoting movement of the separating knife 53. The counter knife 58 is disposed below the plane of the film web 22.

The separating knife 53 or the pivot bearing 54 is slidably mounted on the support wall 55 in order to adjust the cutting or separating plane. As a result, the production of bags 10 of different width is possible. The counter knife 58 is moved as a unit. The pivot bearing 54 is mounted for this purpose on a support 60 which is slidably mounted, in particular on the support wall 55. The separating blade 53 and the Schenklager 54 is under the pressure of a spring 61 in the direction of the counter knife 58, so always a precise Cut is guaranteed.

The separated bags (including tape 18) are taken over by a connecting conveyor, namely the bag conveyor 62. This transported the bag 10 with distance from each other in the area of the transfer station 28. In this bag 10 are sequentially detected and transferred to a filling and closing unit to a bag turret 63. The device is designed so that several, in the present case, four bags 10 presented on the bag conveyor 62, detected and passed to the bag revolver 63. The filled and sealed bags are deposited on a discharge conveyor 64 and transported away.

For the displacement of the cutting or dividing plane in the separation station 27 and the bag conveyor 62 and one of the separation station 27 facing the starting area is adjustable. The bag conveyor 62 is designed as a suction conveyor for sufficient fixation of the bag 10 on a top run 80. Below the suction box 81 is arranged for transmitting negative pressure to the upper strand 80. The suction box 81 is telescopically designed to move the receiving end of the bag conveyor 62, namely with a telescopic box 82. This extends up to an upper guide roller 83 for the upper strand 80. The relative position always remains unchanged, since the telescopic box 82 enters the suction box 81 more or less far. Also, the telescopic box 82 is formed as a vacuum source for the upper run 80, that a backup of the bag 10 is guaranteed to the guide roller 83. Furthermore, the belt of the bag conveyor 62 is guided around a compensating roller 84, which is connected to the telescopic box 82 in the present embodiment, but in any case is movable with this. Thereby, the tension in the belt of the bag conveyor 62 is maintained even during the displacement of the receiving end. Below the compensating roller, a further deflecting roller 85 is provided, which guides the belt in the lower run or receives from this.

The transfer station 30 may be designed so that not only a closure means (tape 18), but other blanks on the bag 10 and the prepared film web 22 are transmitted. 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 more blanks are applied, such as a sticker 21 and a coupon 20 or Faltcoupon.

The transfer unit 36 is associated with a transfer roller 37 in this application, on the circumference of the prepared in the manner described film web 22 is transported. The tapes 18 are from a continuous Tapebahn 65 separated by transverse separating cuts and applied by a feed roller 66 positionally accurate to the film web 22, as in connection with Fig. 4 . Fig. 6 described. The tape web 65 is pulled off a roller 67. A cutting unit 68, shown only schematically, successively divides transverse tapes 18 from the correspondingly formed tapebelt 65. This is provided on one side (top) with permanent adhesive and the edge with a continuous tack-free strip to form the grip tab 19th

A coupon unit 69 and a sticker unit 70 are arranged upstream of the transfer unit 36 in the transport direction. The units 69 and / or 70 are positioned in the region of a horizontal track section 71, above the transfer unit 36. The units 69 and 70 are formed largely coincident. The coupons 20 on the one hand and the stickers 21 on the other hand are each arranged on a carrier foil 72. This is subtracted from a roll 73. Analogous to the embodiment according to Fig. 4 . Fig. 6 In this area, the carrier web 72 is deflected sharp edge, in an area immediately above the film web 22. In the region of a Umlenkungswandung 41 of the respective blank 20, 21 of the carrier web 72nd peeled off and lies exposed. A pressing member, namely an upwardly and downwardly movable punch 75, presses the relevant blank with a downwardly directed glue surface to the film web 22. The empty carrier web 72 is wound up to form an empty spool 76th

The film web 22 is transported in the region of the aggregates 69, 70 in such a way that the pocket front wall 12 or the web leg 24 is directed upwards, that is to say it is exposed. In the exemplary arrangement of the blanks 20, 21 on the bag ( Fig. 1 ) are the aggregates 69, 70 offset in the transverse direction of the film web 22 to each other, wherein the coupon unit 69 is approximately centrally aligned with the web region 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 advantage of the film web 22. Alternatively to the embodiment according to Fig. 4 . Fig. 6 , the transfer unit 36 for the tape 18 may also be positioned in the region of a horizontal track section 71. However, in such a variant, 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. Even with a design of the tape unit 36 analog Fig. 5 the transfer of the tape to the transfer roller 37 can be effected by means of a punch, correspondingly the aggregates 69, 70. In this variant, the film web 22 must stand still during the transfer of the tape.

With regard to the movement characteristics of the film web 22, it generally applies that it is transported by a tape unit 36 with a rotating transfer member during the transfer of the tape 18, but otherwise is stopped in cycles to carry out the severing cut in the area of the separation station 27.

Fig. 11 shows a possible variant of the transfer station 30 according to embodiment of the 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 Fig. 11 united with the transfer roller 37. This is in the edge area 44 (FIG. 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, at the edges of which the adhesive-coated, exposed area of the tape 18 rests. The round belt 51 wraps almost completely in this embodiment, the transfer roller 37. A guide roller 78 performs an upper strand back in the horizontal direction to a further guide roller 79, which is located directly above the plane of movement of the bag 10 and is aligned with the circumference of the transfer roller 37.
