Description

The invention relates to packages for cigarettes having the features of the preamble of claim 1.

Packings for cigarettes consist of a sealing block as an inner pack and an outer pack, in particular in the form of a folding box. The sealing block is provided with an opening aid in which a reusable, fixed by suitable adhesive closure tab can be brought by pulling in the open position and then back to the closed position. In the open position, a removal opening of the sealing block is exposed.

Also known are packages in which the closure flap is fixed with an actuating tab on the inside of a lid - lid front wall - a folding box. When opening the lid of the outer pack, therefore, the closing tab is (automatically) moved into the open position. When closing the lid so also the closure position is created ( WO 2013/120913 ).

It is an object of the invention to further develop and improve the technology with regard to the construction, the functionality and the production of sealing packs for cigarettes, in particular with regard to the structure of the opening aid.

To solve this problem, the package according to the invention with the features of claim 1 is formed.

A peculiarity of the innovation is therefore that the removal opening does not arise when opening the package for the first time by removing an opening piece or an opening tab of the sealing block. Rather, the sealing block is provided with a prefabricated removal opening. Preferably, when the sealing block is made from a film blank, it is applied in the region of a (continuous) film web for the production of blanks for the sealing block, by cutting or punching in a position corresponding to the pack position.

The opening or removal opening is (completely) covered by a locking tab. Cover edges are connected by means of permanent adhesive, preferably pressure sensitive adhesives (PSA adhesive) with an edge of the film surrounding the opening. Preferably, the closure flap is also attached in the correct position in the region of the film web, and that alternatively before or after the production of the (removal) opening. Particularly advantageous is a method in which the closure flap is first attached to the film web in a package-oriented position and then an opening forming the removal opening of the package is produced in the region of the closure flap by punching or by laser.

According to a further (independent) invention, the opening aid for the sealing block is integrated into the (laminate) film consisting of at least two layers or individual films. Of the predominantly over the entire surface (by glue) associated layers or films, a layer or single film (on the outside of the film block) forms a closure tab, the other (inner) layer or single film forms the removal opening. In particular, an opening tab is formed by appropriate punching in the region of the inner layer or individual film, which is brought into an open position upon actuation of the opening aid due to connection with the locking tab of the other single sheet and thus creates the discharge opening and releases. A special feature of this design is the selected positioning of glue fields, in particular in a U-shaped surface structure, for the (detachable) connection of elements of the opening aid with each other.

A special feature of the opening aid is that a preferably over the full width of the closure flap extending end or edge-side handle or Actuation tab is free of adhesive and preferably single-layered. The actuating tab is fixed in particular via a glue connection on the inside of a lid front wall of a folding box, so that when the lid is opened, the closing tab reaches an open position.

The exemplary embodiments of the drawings are concerned with the design of packs for cigarettes 10. A shaped cigarette group consisting of (several) rows is content of an inner pack, namely a sealing block 11 formed as a film block.

In the present case, this consists preferably of a blank 12 made of film, in particular of a moisture and aroma-tight film. The group of cigarettes 10 is preferably completely, i. H. on all sides, wrapped by the blank, thus forms a sealing block with inner front wall 13, inner rear wall 14, inner side walls 15, inner bottom wall 16 and inner end wall 17. The blank 12 is formed or around the group the cigarettes 10 folded around, that the inner end wall 17 is free of folds, so forms a continuous closed wall. In this area, an opening aid 18 is attached, which allows easy, especially automatic access to the contents of the package. The film block 11 forms for this purpose a removal opening 19 in the frontal region. Preferably, the removal opening 19 extends in the region of the inner end wall 17 and a subsequent frontal section of the inner front wall 13. The removal opening 19 is preferably arranged centrally, with (significantly) smaller width than the film block eleventh

The removal opening 19 is - when the package is closed - covered by a closure means, in particular a closure flap 20. This covers the removal opening 19 preferably completely and preferably forms around a strip-like projection with longitudinal strips 21 and transverse strips 22. An anchoring strip 23 is permanently connected to the film block 11 , in particular as limbs of the closure flap 20 in the region of the inner rear wall 14. The aforementioned edge strips 21, 22, 23 are connected by gluing to the film block 11, in each case in an edge strip surrounding the removal opening 19. At least the longitudinal strips 21 and the transverse strips 22 are fixed with releasable and multiple-acting adhesive, in particular PSA adhesive.

The closure tab 20 is provided in an end region, namely in the region of a leg projecting into the inner front wall 13, with a gripping or actuating tab 24.

This is at least on the inner front wall 13 facing side free of glue and can be detected thereby. The actuating tab 24 preferably extends over the full width of the locking tab 20 as edge strips thereof.

A special feature is that the actuating tab 24 is connected in the embodiments shown with a movable part of an outer pack 25. The outer package is here a folding box with box part 26 and cover 27. This is connected in the region of a box rear wall 28 with a lid rear wall 29 via a line joint 30 pivotally connected to the box part 26.

The closure tab 20 is connected to the cover 27, such that upon opening the same, the closure tab 20 also comes into open position ( Fig. 3, Fig. 4 ). For this purpose, the actuating tab 24 of the locking tab 20 with the lid, namely with a lid front wall 31, connected. In particular, by glue or by a in the longitudinal direction of the actuating tab 24 extending glue strips 32. This is attached to the outside of the actuating tab 24. In the manufacture of the package or during insertion of the film block 11 in the outer package 25, the connection with the actuating tab 24 is made via the glue strip 32 in the closed position of the lid 27. Preferably, a lid inner tab 33 is attached to the inside of the lid front wall 31. With this the operating tab 24 (permanently) is connected. When closing the lid 27 and the locking tab 20 returns to the closed position ( Fig. 1 ) back.

The film block 11 or sealing block is according to Fig. 1 formed with an envelope fold in the region of the inner side walls 15. Also in the area of the bottom wall 16, overlapping folding flaps are formed, preferably as an envelope fold. The folding flaps are sealed together by thermal sealing. Furthermore, a support member is disposed within the film block 11, in particular a tray 34 of known design, preferably with front wall, side flaps and bottom wall.

A special feature is that the removal opening 19 is at least partially free, that is without the opening tabs 35 lying in the region of the removal opening 19 during the preparation of the blank 12. This is part of the film in the region of the removal opening 19. In the embodiment according to FIG Fig. 1 to Fig. 3 the opening tab 35 is completely eliminated. The blank is therefore provided with a recess which forms the removal opening 19 in the finished package - film block 11. For this purpose, in the area of the unfolded blank, preferably in the area a continuous film web 36 for producing the blanks 12 a precisely aligned to the design of the film block 11 punching attached, in the embodiment of Fig. 1 to 3 a closed punch around punching that leads to a substantially rectangular recess corresponding to the removal opening 19, in particular with slightly converging - to the operating tab 24 - edges. The opening tab 35 thus falls as a blank part and is eliminated.

Alternatively ( Fig. 4 . Fig. 5, Fig. 6 ) a U-shaped punching in the blank 12 and the film web 36 is attached to form an opening. The resulting opening tab 35 remains along an edge 37 in conjunction with the blank 12. The opening tab 35 is here folded out of the region of the removal opening 19 and applied to a wall of the film block 11, present ( Fig. 4 . Fig. 5 The opening tabs 35 are preferably connected to the wall of the film block 11, in particular by bonding and / or by thermal sealing, in the present case with two sealing strips 38 ,

An (independent) feature is the formation of the glue areas or the glue pattern for (releasably) connecting the closure flap 20 to the film block 11 Fig. 5 can be seen, the locking tab 20 is provided with a frame-like, surrounding the removal opening 19 Leimbild. This can be attached during manufacture to the closure flap 20 (which is made of a separate blank) and / or to the blank 12.

The glue pattern (preferably PSA adhesive), in particular with longitudinal strips 21, transverse strips 22 and anchoring strips 23, is formed with a different adhesive action, corresponding to the stress on opening and closing of the film block 11. Preferably, at least the transverse strip 22 is formed with a lower adhesive effect than the adhesive strip remaining sections of the glue pattern. In the present case, initial limbs 39 of the longitudinal strips 21 are formed with a lower adhesive effect, so that in particular the initiation of the opening process for the closure lug 20 is facilitated. The other parts of the glue pattern, namely the longitudinal strips 21 and the transverse strips 22, are formed with a higher holding force, preferably continuously with the same holding force. Alternatively, the anchoring strip 23 may be formed with a further increased holding force to ensure the permanent fixation of the opening tab 20 on the film block 11.

The different holding or connecting effects of the areas of the glue pattern can be effected by appropriate selection of different types of glue and / or achieved by different layer thicknesses and / or by different structures of the transverse strip 22 on the one hand and the longitudinal strips 21 on the other.

This design of the glue connection of the closure tab 20 with the film block 11 can also be used in conventional (sealing) packs and packs accordingly 11 to FIG. 14 be applied. In the mentioned conventional packages may be those in which the opening tab 35 remains in the starting position and is connected to the locking tab 20.

In the film block 11 according to Fig. 1, Fig. 2 and the matching blank 12 according to Fig. 5 the inner side walls 15 are formed by trapezoidal folding tabs. FIGS. 7 to 10 deals with an alternative with regard to the formation of the opening aid 18, but also with regard to the formation of the film block 11. This has in the region of the inner side walls 15 connecting seams in the design as a fin seam. Furthermore, here the inner bottom wall 16 is free of folds. A transverse seam 40 is located in the region of an inner rear wall 14, in particular in the form of a fin seam.

The opening aid 18 is formed in this embodiment so that the blank 12 (FIG. Fig. 9 ) receives a free discharge opening 19 around. Accordingly, in the region of the film web 36, a complete punching is made, producing a (removal) opening 19. The resulting opening flap 35 is disposed of as waste. There remains a free opening, in particular with to the side of the operating tab 24 converging opening edges.

In the embodiments with a closure tab 20 from a separate blank preferably the (PSA) adhesive is attached to the inside of the closure tab 20. Preferably, a glue pattern in the embodiment of a closed frame is provided with the legs or strips 21, 22, 23. A central region of the closure flap 20 is free of glue and preferably provided with a printing 61. The glue fields or strips are slightly set back relative to the (removal) opening 19, so that a narrow, glue-free strip is preferably formed around, approximately 1.5 mm wide.

In the area of a glue-free part of the closing tab 20, namely in the region of the actuating tab 24, the glue patterns are attached to connect the actuating tab 24 to the inside of the lid front wall 31. Two alternatives are shown: A closed, continuous glue strip 32 can be attached , Alternatively, a number of adjacent glue spots 41.

A particular embodiment with respect to the sealing block or film block 11 and in particular in the area of the opening aid 18 is shown in FIG Fig. 11 to Fig. 13 shown. The film for the film block 11 is multi-layered, consists in particular of two layers or individual films 42 and 43 (FIG. Fig. 14 ). These layers or foils 42, 43 are-predominantly-interconnected by a glue layer 44 of preferably non-releasable glue, so that in this area the individual foils 42, 43 form a non-separable film unit.

Preferably, at least one of the individual foils 42, 43, in this case the inside single foil 43, is formed as aroma- and moisture-proof, preferably by a (metallic) barrier layer 45 applied by vapor deposition. This is located here within the multilayer foil. The glue layer 44 therefore connects the individual foils 42, 43 in the region of the barrier layer 45.

The formed in the manner described multilayer film may be provided with an opening aid 18, which corresponds to the previous embodiments. However, the structure of the film allows a specially designed opening aid 18, which is integrated into the film using the individual films 42, 43.

The closure tab 20 is formed by the outer single film 42. The inner individual film 43 is processed so that it forms either an opening attached to the production as removal opening 19 or a detachable with the help of the locking tab 20 during the opening opening opening tab or an opening tab 35. This is, as shown, connected by preferably full-surface gluing (inside) with the locking tab 20.

The opening aid 18 is in this pack in the region of the blank 12 ( Fig. 13 ), but preferably in the production of the (multilayer) film - film web 36 - prepared by specifically applying different types of glue, by forming glue-free areas between the individual films 42, 43 and by selective attachment of dividing lines in the individual layers 42, 43rd ,

The attachment of the opening aid 18 is integrated into the production process of the film or the film web 36. When joining the layers or individual foils 42, 43, surfaces are preferably recessed or provided with glue at the same time or offset, which are required for the functionality of the opening aid 18. In the present example, a preferably U-shaped surface between the individual sheets 42, 43 provided with releasable glue (PSA adhesive), analogous to the described embodiment for forming longitudinal strips 21, transverse strips 22. Alternatively, a partial or full coating with glue to be appropriate. Furthermore, with regard to the attachment of the glue layer 44, a strip-shaped, rectangular free zone 46 is created. In this area there is no glue, so neither the glue layer 44 nor the (PSA) glue the opening aid 18. Here is the handle or operating tab 24th

To form closure flap 20 and / or opening flap 35, separating cuts or lines are made in the region of the opening aid 18 to be produced, preferably in the film finished with respect to the layers 42, 43, 44, 45. The dividing lines which are applied only in the region of a layer are preferably produced by laser and are therefore limited in terms of their effectiveness to the relevant layer.

The outer contour of the closure flap 20 consists of a preferably continuous, ie uninterrupted, substantially U-shaped cutting line 47 (only) in the region of the outer layer, ie the individual film 42. This cutting line extends with preferably approximately parallel legs in the region of the inner end wall 17 (at least partially) and a subsequent, frontal region of the inner front wall 13. In the embodiment of the Fig. 13 A transverse leg extends in the inner front wall 13 and limits the actuating tab 24. The section line 47 determines the outer contour of the locking tab 20th

The inner individual film 43 forms the removal opening 19 by removing the opening tab formed by the individual film 43, which is connected in the present example with the closure tab 20, preferably by the correspondingly arranged glue layer 44. The contour of the opening tab 35 is preferably also about U shaped weakening line 48, which is limited by applying appropriate technologies (laser) on the single film 43 (including the thin barrier layer 45). The weakening line 48 can be formed as a perforation-with residual connections-but preferably as a continuous cut line.

In the present case, the arrangement is such that the ends of the cutting line 47 on the one hand and the weakening line 48 on the other end - in the region of the inner rear wall 14 - adjacent to each other.

The glue pattern of the opening aid 18, that is to say the U-shaped glue pattern with longitudinal strips 21 and transverse strips 22, is in terms of the glue thickness in the manner described ( Fig. 5 ) educated. The glue strips 21, 22 are dimensioned so that the cutting line 47 and the weakening line 48 - the latter are completely in the region of the glue pattern 21, 22, of course, except for the contour for the actuating tab 24. The glue field preferably PSA adhesive is out FIGS. 13 and 14 seen, slightly wider than the distance between the cutting lines 47 and lines of weakness 48, so that in this area the dividing lines are covered by the releasable adhesive.

The so-formed opening aid can be operated by hand (by detecting the actuating tab 24). In the present example, the operating tab 24 is connected in the manner described with the inside of the lid 27 of a designed as a folding box outer pack 25, so that an automatic opening and closing is ensured. As in particular from Fig. 12 it can be seen, the (multilayer) film is completely separated from the composite during the opening process in the region of the removal opening 19 to be produced.

The outer packs 25 are preferably designed as hard packs, in particular as a folding box. This can be provided without collar, but alternatively also with a conventional collar 49 ( Fig. 8 ). The collar is provided with a front recess 50, which is bounded in the region of the front side by lateral collar webs 51. Preferably, the recess 50 - between the collar webs 51 - - is formed so that it extends to a closing edge 52 of the package or the box part 26. In this area - between the collar webs 51 - is the locking tab 20 and in particular the actuating tab 24th

In packs with a fixation of the actuating tab 24 of the opening aid 18 on the inside of the lid front wall 31, a contact pressure on the outside of the lid front wall 31 is preferably exercised after completion of the pack, preferably in the range of a device (in particular dry turret). The pressure is specifically transmitted by a special pressure piece on the lid front wall 31 in the region of the connection with the actuating tab 24 - with the lid closed 27 - transferred. In a pack with collar 49 in the region between the collar webs 51st

This makes it possible to use a lid inner tab 33 in the folding boxes as outer package 25, which preferably extends over the full (transverse) dimension of the lid front wall 31. A certain deformation of the lid front wall 31 is canceled by the restoring forces of the material after completion of the pressure load.

The opening aid is preferably produced completely in the region of a continuous film web 36. Fig. 15 and Fig. 16 relate to different concepts for an opening aid according to Fig. 4 . Fig. 5 , So with the blank 12 hanging opening tabs 35th According to Fig. 15 remains a shortened (residual) connection of the formed by punching 53 lobe 35 with the film web 36, so a shortened edge 37. The opening tab 35 is detected during transport of the film web 35, lifted and transferred until it rests against the film web outside the area the created removal opening 19. For this purpose, in the region of a deflection - deflection roller 54 - raised with respect to a front edge. The opening tabs 35 can now be detected by a lifting member, in this case by a (curved) tapered lifting rail 55. By transporting the film web 36 of the flap 35 is raised and finally folded. This results in the region of the web, the positionally accurate removal opening 19th

Subsequently, in the region of the removal opening 19, the closure flap 20 is applied to the film web 36 under exact alignment in the region of a vertical transport section of the film web 36. The closure tab 20 is pressed as a separate blank of a carrier web 56 in the region of an acute-angled deflection of the film web 36, on the side opposite to the tab 35 (outer) side of the film web. Thereafter, the film web 35 enters the region of a separation station 57. Here, the blanks 12 are separated by transverse cutting knife 58 successively from the web 36. Alternatively, the film web 36 can be folded around a series of groups of cigarettes to form a continuous, tubular casing, from which by cross-section (in particular in connection with a sealed seam) packs - film block 11 - are separated, in particular in WO 2014/195016 removable way.

A special feature is that the work on the film web 36 and in particular the exact positioning of elements of the opening aid 18 are controlled by supervisory bodies. Thus, sensors, in particular optoelectronic sensors 59, are preferably in the region of the vertical transport path the film web 36 is positioned in the region of a control station. These sensors 59 are designed to detect the presence of the (extraction) opening 19, both in terms of correct relative position and in terms of correct formation (dimension, contour). After passing through the sensors 59, there is certainty about the correct arrangement of the opening 19.

Following the transfer station for the closure tabs 20, another (stationary) inspection station with sensors 60 is installed on both sides of the web 36. These (electro-optical) sensors detect the presence of the locking tab 20 in the correct relative position. The free side of the closure flap 20 is preferably provided with a print 61, namely on the inside of the closure flap 20, with advertising and / or informational indications that can be detected by the sensors 60.

The separating cut for producing the blanks 12 is preferably controlled by printing marks 62.

The film web 36 is also assigned a sealing member 63 for attaching the sealing strips 38. In the present case, this is a rotatable sealing wheel with a plurality of sealing jaws 64 arranged parallel to one another along the circumference. This organ, if necessary, can also be controlled by the sensors 59.

The execution according to Fig. 16 differs from the preceding embodiment in that the closure tabs 20 are already mounted in a pre-laid transfer station on the web 36 - in the area of the punching 53, which is in particular attached first. Thereafter, the process already described for lifting the opening flap 35 and for folding this flap 35. The film web are also in the embodiment of Fig. 16 Assessed control organs (sensors), in particular, the presence and the correct formation of the opening 19 and the presence of the locking tab 20 examine.

The device according to Fig. 17 is designed so that the opening tabs 35 is removed, so that a universally free (removal) opening 19 is formed. For this purpose, a punching unit 65 is preferably provided in the region of a horizontal transport path of the film web 36, which in the present case consists of a punching roller 66 with a punching knife 67 and a counter-roller 68. The punching knife 67 is as formed around closed, approximately rectangular knife, which attaches a corresponding opening 19 positionally accurate in the web 36.

Thereafter, the web is deflected. In the region of a vertical conveyor section inspection or control organs of the described embodiment are positioned and also a transfer station for attaching the locking tab 20 in the region of the openings 19. The resulting in the punching station by the punching unit 65 pieces of material corresponding to the opening 19 are eliminated, in this case by a Collecting funnel 69, in particular with suction effect.

A special production technology for the preparation of the film web 36 for producing blanks of the film packs is in Fig. 18 and Fig. 19 shown. The (sealing) film web 36 is preferably moved along upright and transverse transport paths. A first (upright) track section 70 is provided for upward movement of the track 36. This is deflected by deflecting rollers 71, 72 into a preferably horizontal track section 73 and then back into a preferably downwardly directed track section 74. The closure flap 20 is preferably fed to the vertical web section 70 and applied to the film web 36 in a package-oriented manner, preferably at the web outside or top side. Preferably, in the region of the horizontal track section 73 is a special punching unit 65 with a punching roller 66, which preferably acts below the (horizontal) film web 36. A counter roll 68 is mounted above the web 36.

The blanks of the closure tabs 20 are preferably arranged close together on a continuous carrier web 56. This is deducted from a reel 75. The carrier web 56 is fed to a transfer station 76. In their area, the decrease of the closure tabs 20 of the carrier web 56 and the precise transfer to the film web 36. The carrier web 56 is led around for this purpose around an acute-angled deflecting member 77, whereby the adhesive adhering to the carrier web 56 closing tab 20 peeled off and to the passed at an acute angle to a leg of the carrier web 56 running film web 36. The locking tab 20 is fixed in the exact position by a pressure roller 78. The pressure roller 78 is opposite a counter-element, in this case a support plate 79th

In the subsequent punching or separating station or in the punching unit 65, the film web 36 is in the region of the respective locking tab 20 on the free (lower) side a preferably closed dividing line attached, preferably by punching, the one of the opening (removal opening 19) corresponding piece of film - opening tabs 35 - separates out. The punching unit 65 is precisely controlled, such that the opening is produced in exact alignment with the closure tab 20 outside the gluing, by means of a separating cut exclusively in the area of the film web 36.

The punching roller 66 is provided along the circumference with preferably several, in particular two punching units, ie corresponding groups of punching blades 80. These are preferably designed as a closed blade frame for producing a closed dividing line in the film web 36.

The opening tab 35 is conveyed away by suction. Preferably, the punching roller 66 is provided with suction holes 81 in the area of the punching blades 80. These (multiple) suction holes are within the surface area of the opening tab 35 so that it is fixed under application of pressure on the circumference of the punching roller 66 and taken with the rotation of the same. By venting the opening tabs 35 is released and can be disposed of.

For this purpose, a special measure is provided: On the underside of the punching roller 66 and below it is a suction unit 82. The suction holes 81 of the punching roller 66 are preferably controlled so that takes place at the bottom of the rotary motion switching to compressed air. Accordingly, compressed air is transmitted via the suction bores 81, which leads to a lifting of the opening tab 35 and to the transfer to the suction unit 82. This takes over the film piece 35 in a suction 83.

The thus prepared film web is fed in the manner described a separating station for producing the blanks or foil packs.

The carrier web 56 freed from the closure tabs 20 is returned and received by a collection bob 84. The drive of the carrier web 56 takes place in this area without closure tabs 20 by a drive roller 85. The carrier web 56 is thus pulled over the deflecting member 77.

Important are monitoring or control organs for correct positioning of closure flap 20 and / or opening 19 in the preferably continuously driven film web 36. First, the positionally accurate transmission of Closure tab of the carrier web 56 on the film web 36 by sensors (not shown) monitored and controlled, preferably in conjunction with print marks on the film web 36. Then, with continued (continuous) transport of the film web 36, a first (optoelectronic) sensor 86 effective, preferably in the region of the upright web portion 17, on the side of the arrangement of the closure flap 20. The sensor 86 is arranged and effective so that at least one preferably transverse edge of the closure flap 20 is detected. From this, a signal for the control of the punching unit 65 is derived, namely with regard to a precise attachment of the parting line for the production of the opening 19th

Another sensor 87 is effective after the punching unit 65, on the inside of the film web 36 - preferably in the region of the downwardly directed web portion 74 - for detecting the punched hole or opening formed. This sensor 87 also detects the presence of the locking tab 20 in exact relative position to the (removal) opening 19. For this purpose, the free inner side of the locking tab 20 is provided with markings and / or colorations, which provide a fast, reliable detection by the sensor 87 ensure the differently shaped film web 36. <B> LIST OF REFERENCES: </ b> 10 Cigarette 49 collar 11 slide block 50 recess 12 cut 51 neckband 13 Interior front wall 52 closing edge 14 Inner rear wall 53 punching 15 Interior sidewall 54 deflecting 16 Inside bottom wall 55 lifting rail 17 Inside front wall 56 support web 18 opening aid 57 separating station 19 removal opening 58 separating knife 20 flap 59 sensor 21 vertical stripes 60 sensor 22 tuck 61 Oppression 23 anchoring strips 62 print mark 24 operating tab 63 seal organ 25 overpack 64 sealing jaw 26 box part 65 punching unit 27 cover 66 punching roller 28 Box rear wall 67 punching knife 29 Lid rear wall 68 backing roll 30 line joint 69 receiving hopper 31 Lid front wall 70 web section 32 glue strips 71 deflecting 33 Lid inner tab 72 deflecting 34 tray 73 web section 35 opening tab 74 web section 36 film web 75 reel 37 edge 76 transfer station 38 sealing strip 77 deflecting 39 early leg 78 pressure roller 40 cross seam 79 support plate 41 spot of glue 80 punching knife 42 Single sheet 81 suction bore 43 Single sheet 82 suction unit 44 layer of glue 83 suction 45 junction 84 Sammelbobine 46 free zone 85 drive roller 47 intersection 86 sensor 48 weakening line 87 sensor
