Definitions
- the present invention concerns an apparatus for handling a tobacco pouch-like packaging that is handled in a number of operation units, for example an insertion unit for advancing packagings one by one into the apparatus, an opening unit, a filling unit, a welding unit, a folding unit and a laying unit, and a method for handling a tobacco-pouch-like packaging that is handled in a number of operations, including operations for inserting packagings one by one into an apparatus, opening the storage compartment of the packaging, filling the packaging with desired content, welding for closing the storage compartment of the packaging, folding for winding the flap of the packaging around the storage compartment, and laying off the filled and closed packaging from an apparatus.
- Prior art tobacco-pouch-like packagings can be made as so-called flat pouches or so-called side-folded pouches.
- the present invention concents both types of packaging.
- a tobacco-pouch-like packaging is usually made of plastic. There may be provided a print directly on the plastic, or there may be provided a paper provided with print with information about the product in the packaging, where the paper is disposed between two plastic layer that are welded together.
- the packaging has a storage compartment formed between two overlaid surfaces that are mutually connected along side edges. The bottom of the storage pouch will normally be formed by folding along a long sheet of packaging for bringing this to overlie itself over a part of the length. At the non-overlaid part of the packaging sheet, a flap is formed that may be used for folding down around the storage compartment. At the dosing of the storage compartment there will usually occur simultaneous folding of an uppermost edge area on the two overlaid sheets.
- the flap may extend over a greater or lesser length of the storage compartment.
- the folded flap may thus only extend down along a from side of the storage compartment.
- the flap may extend down along the front side, under the bottom and up along the back side of the storage compartment and become attached at the back side of the storage compartment of the packaging.
- front side, back side and bottom in relation to the packaging reference is made to a normal situation of use where the front side is the side disposed opposite to the flap, and the back side is the side of the packaging where the flap is extending in continuation of the wall of the storage compartment.
- Such packagings are normally dosed with a strip of adhesive tape provided at the extreme end edge of the flap.
- the tape strip is brought into engagement and is released from engagement with the side wall on the storage compartment, but will be fastened with greater adhesive ability to the edge area on the flap.
- Such tape strips have tendency to be twisted and distorted or to be damaged by a product adhering to the tape strip, possibly implying insufficient reclosing.
- the method and apparatuses that have been used by handling such pouch-like packagings in order to fill these, are traditionally provided by a series of successive operations that are performed in separate operation units.
- an operation unit including a magazine from which the pouches are advanced one by one to a subsequent apparatus.
- the pouch is transferred to grippers in one unit to grippers in the succeeding unit.
- the succeeding unit will traditionally be intended for performing opening the pouch so that this can be filled in an additional succeeding unit.
- such pouches are filled by disposing at a horizontal or vertical position, as a previously packed amount, e.g. of tobacco, is introduced into the storage compartment, simultaneously with a continued movement is releasing the pouch from the grippers in the filler unit. After that, the pouch is transferred to and is gripped by a winding unit which provides for winding or folding the flap around the storage compartment.
- a winding unit which provides for winding or folding the flap around the storage compartment.
- the pouch now wound is provided with a tape strip for securing the flap.
- the presently filled and closed pouch is passed through a laying unit for transfer to further units for handling in connection with packaging, pricing etc.
- the prior art apparatuses are very expensive and technically complicated as well as difficult to change if pouches with different sizes are to be filled. Furthermore, there is a risk of misplacing pouches when these are transferred from one operation unit to another operation unit in which the different process steps in the filling operation are performed.
- US-A-3 982 376 discloses an apparatus in which a chain is used which comprises grippers for supporting pouches. There is no disclosure of a conveyor belt which covers a plurality of vacuum chambers.
- US-A-3 842 568 discloses a method for packaging a tobacco-pouch-like bag.
- a vacuum behind the belt is used for securing the bags to the belt when they are advanced in a predetermined direcdon. It is disclosed how the packagings are reeled on themselves and after that are stripped in a direction transverse to said predetermined direction and then the bags are tamped into a carton. There is no disclosure for handling the bags in operations for opening, filing, welding, closing folding and laying off the bag.
- Hitherto known operation units for applying labels are typically very complicated if a very secure handling is to be achieved for avoiding that more than one label is transferred at a time. This is particularly the case with very small labels.
- the duty per revenue label can be considerable, and by such revenue labels it is therefore particularly important that only one revenue label is used per packaging, and that at the same time it is ensured that each packaging has been labelled with regard to duty calculation for the goods provided in the packaging.
- the known operation units for applying labels on packaging have been based on vertically oriented label stacks, where the label to be transferred from magazine to the packaging is taken out from the bottom of the stack. This has resulted in a problem since there is varying pressure depending on the amount of labels in the stack. Too large amount of labels may thus cause that carrier means in the transfer means cannot take out the lowermost label in the stack since this it is pressed too hard against retainers, and that the transfer means have insufficient strength for releasing the label from the stack.
- an apparatus of the kind mentioned in the introduction being peculiar in that it is made with the operating units as modules which are mounted at juxtaposed stations on a common name that includes a support for an endless conveyor belt, that the frame is supporting an endless conveyor belt provided with packaging attachment means that are disposed with mutual spacing corresponding to centre distance between two succeeding stations so that each packaging may be secured on the endless conveyor belt as they are in contact with an outwards facing surface, that the frame includes a number of juxtaposed vacuum chambers in a number corresponding to the stations, and that the endless conveyor belt covers the vacuum chambers and is provided with attachment means in the form of a repeated pattern of apertures so that packagings are sucked into abutment against an outwards facing surface on the endless conveyor belt, that the frame includes a number of juxtaposed vacuum chambers in a number corresponding to the stations, and that the endless conveyor belt covers the vacuum chambers and is provided with attachment means in the form of a repeated pattern of apertures so that packagings are sucked into abutment
- the apparatus is designed with an operation unit for attaching labels to a packaging and including a magazine for the labels and means for advancing and transferring labels from the magazine to the packaging, and is peculiar in that the labels are provided in a largely horizontal stack in the magazine and are resting with their lateral edge on a bottom surface in the magazine, that a block is placed on the bottom surface in abutment with the rearmost label in the stack and is pressing the stack forwards against the transfer means, preferably due to its frictional engagement with the bottom surface as this bottom surface is adapted for advancing the block and thereby the labels towards the transfer means, that the transfer means include a suction cup which is mounted in a bracket being displaceable in direction against and away from the packaging and which is rotatable about an axis that is oriented perpendicularly to the longitudinal direction of the magazine.
- the amount of labels in the magazine will not influence the form with which they are to be removed.
- the label stack is thus placed with its side edge in contact with the bottom surface.
- a block having appreciable weight compared with the label is disposed on the same bottom surface and will thus exert a constant pressure against the label stack, depending on the advancing of the bottom surface. The block will thus press the label stack against retainers that are placed in immediate vicinity of the transfer means.
- an operation unit being peculiar in that the magazine includes guide rods capable of being positioned for abutment against the lateral edges of the labels, and that at a front end of these guide rods there are retainer surfaces on projections directed towards the stack for retaining the stack but allowing the foremost label in the stack to be taken out by the suction cup.
- the guide rods can be adjusted for adapting the apparatus to different label sizes. Possibly, there may also be provided guide plates at the top of the labels.
- the method according to the invention is peculiar in that the packaging is fixed and attached to an endless conveyor belt through and between the process steps of the handling, as there is established an attachment to the endless conveyor belt so that each packaging is secured to a side of the endless conveyor belt and is advanced through a number of stations where the process steps can be performed, that the securing is established by forming vacuum behind the endless conveyor belt so that the securing of the packaging is effected by suction to an outwards facing surface of the endless conveyor belt, as the endless conveyor belt is provided with a pattern of apertures and that the packaging is suspended via its flap with the opening of the storage compartment facing upwards and outwards in relation to the endless conveyor belt.
- each packaging may be indexed correctly in each operation unit for the individual steps of the method may be performed in a safe way with the packaging correctly positioned.
- the endless conveyor belt with mechanical grippers.
- Such mechanical grippers may e.g. be spring-loaded jaws that are gripping the flap around the top thereof and possibly also at the side of the flap.
- the grippers can be arranged for activation and deactivation of the central control unit, either by application of actuator acting directly on the jaws of the grippers, or by moving the grippers through cam guides that serve to open the jaws and hold these closed during the passage of the packaging through different handling steps.
- the apparatus will preferably be controlled by a central control unit which is connected with a number of sensors, e.g. for registering the presence of a packaging in an operation unit. If it is registered that a packaging is present in the operation unit, this may be deactivated in the process step concerned. Hereby is e.g. avoided that material is delivered by the filling unit and produces contamination if no packaging is present in the unit. Also, it is important that the unit applied adhesive for use in reclosing the packaging is only activated if a packaging is registered in the station concemed in order to avoid adhesive being deposited on the endless conveyor belt, thereby disturbing or hindering continued operation of the apparatus.
- the operation unit for labelling may, according to an aspect of the invention, be peculiar in that the magazine is adapted to perform reduction in the pressure in the label stack at the time of taking out the foremost label in the stack.
- the magazine is adapted to perform reduction in the pressure in the label stack at the time of taking out the foremost label in the stack.
- the operation unit may therefore operate independently of the weight of the labels and hence of the friction with the bottom surface.
- suction cup provides a particular high degree of safety for only taking one label, as the suction cup may only engage the outermost label in the stack. This is substantially different from mechanical conveying means that displace the labels laterally in relation to the longitudinal direction of the stack.
- the label may possibly be brought in contact with means for activating adhesive on the labels or means for applying adhesive to the labels.
- the label is applied in a secure way with the mutual displacement of the section cup and the label. Then the suction cup is deactivated, and this may be passed back to its initial position for receiving a new label from the stack.
- the bottom surface of the magazine is formed by the upper course of an endless belt This may be advanced continuously or intermittently. It is preferred to provide an intermittent movement which preferably will be synchronised with the label transfer.
- an intermittent movement which preferably will be synchronised with the label transfer.
- the bottom surface may possibly be formed by other bottom surfaces, e.g. a slotted surface, where carrier rods or points are moved up through the slots and displace the stacks forwards along the upper side of the slots.
- the magazine is arranged displacing in direction against and away from the bracket for the advancing means in order to bring the foremost label in abutment against the suction cup when this is directed against the stack.
- the bracket supporting the suction cup is rotatable about a mainly vertically oriented axis.
- the label is pivoted during the transfer from the stack to the packaging in a horizontal plane, which simplifies the design of the machine, as the stack can be disposed in alignment with the support means intended for securing the packaging in a simple way.
- the packaging with the surface intended for receiving the label will be disposed in direct continuation of the longitudinal direction of the magazine so that the suction cup is only to be rotated through about 180° for aligning the label with the packaging. Then the bracket is displaced against the packaging. This also occurs with a displacing movement which is oriented in the longitudinal direction of the magazine.
- the operation unit will particularly suited for use in applying labels in the form of revenue labels on tobacco packagings in the shape of tobacco pouches which are handled in the apparatus and the method according to the invention.
- the bracket of the operation unit may alternatively be rotated through another arbitrary angle that aligns the label with the packaging.
- a servomotor for rotating the bracket, it is possible to adapt the angle to different packagings in a simple way.
- Fig. 1 illustrates a tobacco-pouch-like packaging 1.
- the packaging 1 is provided with a flap 2 intended for folding over an opening 3 for a storage compartment 4 in the packaging.
- the storage compartment 4 is formed by a part of an elongated packaging item 5 having been folded around a bottom 6 for covering a rear wall 7 in the storage compartment.
- the rear wall 7 is extending further up in the flap 2.
- the packaging is provided with folding lines 8 which are disposed at a small distance under the opening 3 so that by folding a closing over both overlaid sidewalls 5, 7 in the pouch is effected.
- folding lines 8 which are disposed at a small distance under the opening 3 so that by folding a closing over both overlaid sidewalls 5, 7 in the pouch is effected.
- a further folding line 9 as the flap 2 is of such length that it is intended to be folded about the front side 5 of the storage compartment under the bottom 6 around the rear wall 7 in order to be fastened thereto.
- the fastening occurs by means of a releasable closing means in the shape of an adhesive strip 10.
- the adhesive strip 10 is placed on the side edge 11 of the flap 2 at the end facing away from the opening 3.
- the adhesive strip 10 is placed on the inwards facing surface which by folding of the flap will cause the adhesive to adhere releasably on the corresponding closing means in the shape of the external plastic surface of the rearmost sidewall 7 of the storage compartment.
- the flap 2 may be shorter so that the folding line 9 is omitted, and so that the flap 2 only extends down to a point at the front wall 5 of the storage compartment.
- front wall 5 and the rear wall 7, respectively, may be provided with separate areas provided with adhesive which are particularly adapted to interact releasably with the adhesive 10 on the flap 2.
- the adhesive strip 10 there is used a hotmelt adhesive.
- other closing means which can interact in a releasable way. This can e.g. be the case with Velcro®-like fasteners, snap fasteners, or the like.
- Fig. 2 is seen that the apparatus 12 is modular with a number of juxtaposed stations 13 that each are intended for receiving an operation unit. Opposite to each station 13 there is provided a vacuum chamber 14 shown with broken line in Fig. 2. The vacuum chambers 14 are seen more clearly in Fig. 3. It is seen that the vacuum chambers are connected with pipes 15 that are connected with a side duct blower (not shown) via a valve arrangement enabling individual vacuum formation or interruption of vacuum.
- FIG. 2 is schematically illustrated a number of fastening means 16 intended for fastening the operation units.
- the operation units will thus be fastened at a laterally oriented section of the apparatus and face an operator.
- An endless conveyor belt 17 is running about a reversing roller 18 oriented about vertical rotational axes 19.
- the endless conveyor belt 17 is provided with the repeating pattern of apertures 20.
- the distance between centre points in the aperture patterns 20 corresponds to the centre distance between to succeeding vacuum chambers 14.
- an aperture pattern will be placed over a vacuum chamber when the endless conveyor belt 17 is with a packaging item (not shown) that is sucked on by the vacuum in the vacuum chamber acting through the apertures 21 of the aperture pattern at a position opposite to an operation unit.
- juxtaposed vacuum chambers 14 are only separated by a rather thin partitioning wall 22.
- packagings sucked on via their flap 2 on the endless conveyor belt 17 will be positioned and indexed correctly throughout subsequent work stations 13, as they are secured onto the endless conveyor belt 17 throughout the entire conveying through the apparatus 12.
- mechanical grippers e.g. with a gripping chain having a row of jaws for gripping the flap. In this way there will be an endless conveyor belt without need for vacuum chambers lying behind.
- Fig. 2 a single packaging 1 in a position which it is usually having when it is on the endless conveyor belt 17. It is seen that the storage compartment 4 will be placed under the endless conveyor belt 17, whereas the flap 2 will be disposed opposite to the endless conveyor belt 17. Thus it is possible to have a plane contact surface which in a secure way is in contact with the endless conveyor belt 17, thereby being secured by the sub pressure produced through the apertures 21.
- the endless conveyor belt 17 will slide in a recess 33 in the frame of the apparatus and thereby close the vacuum chambers 14. At the underside of the recess there is a guide rail 24 supporting the back side of the flap 2 of the packaging through the course.
- Fig. 4 shows a partial view of an insertion unit 26.
- the insertion unit includes a conveying channel 27 with a conveyor 28 advancing the packagings.
- a roller 27 advances the packaging items so that they are placed stacked in a magazine 30.
- An indexing arrangement 31 ensures that packagings are advanced individually to a roller wheel 32 that faces orientation of the individual packagings and are placing these with a vertical orientation in contact with the endless conveyor belt 17 at a position opposite to a first vacuum chamber 14 so that the packagings are individually sucked onto the endless conveyor belt 17.
- the opening unit 33 includes a displaceable plate 35 which can be displaced back and forth via a piston 36.
- the plate 35 is connected to a vacuum source via tubes 37.
- An opening unit 33 is provided with a piston 38 at its upper side, and which at its lower end includes a mandrel that is inserted in the packaging opened after actuation of the piston 36.
- the width and stroke of the piston thus ensures complete opening of the storage compartment.
- holders of which one is seen schematically at 39 and a support at the bottom (not shown), ensure that the bottom is supported when the piston 38 is activated.
- the opened packaging is then moved to the filling station 34.
- filling is effected via a filling duct 40 opening into the storage compartment 4 of the open packaging.
- a vacuum suction cup 41 at the front wall 5.
- a further vacuum suction cup 42 is shown at the rear wall 7 for further stabilising the storage compartment.
- the vacuum suction cup 42 may, however, be omitted.
- the flap 2 is stabilised in that a holder 43 by activation of a cylinder 44 is pressed into abutment against the endless conveyor belt 17 at each side of the filling duct 40.
- the packaging 1 is thus completely fixed when the content is inserted into the storage compartment. Hereby is avoided risk of faulty indexing of the packaging under the physical actions that appear at the filling of content itself.
- This content can be of different character. It may be packed items like tobacco or the like. Also it may be granular material in the shape of tablets, pastilles, or similar.
- Fig. 6 illustrates the filling unit 34. It is further seen that a piston 45 is connected with the suction cup 41 enabling its insertion into and retraction from the packaging.
- Fig. 7 an operation unit 46 that follows the filling unit.
- the operation unit 46 constitutes a welder enabling welding of the opening 3 of the packaging by welding the edge area adjoining the opening 3.
- the operation unit thus includes a welding jaw 47 which is suspended in pistons 48 so that it may be displaced back and forth for engagement with the bag, as this is pressed into abutment against a retainer plate 49 which is placed in position at the side of the endless conveyor belt 17.
- Fig. 7 shows the subsequent operation unit 50 which is an embossing unit making indication for folding lines 8 and 9.
- Fig. 8 shows more clearly the embossing unit 50 with an upper die 51 intended for embossing the folding line 9 by pressing against the endless conveyor belt 17 itself or a dolly plate (not shown) disposed at the side of the endless conveyor belt 17.
- the apparatus further includes a lower die 52 intended for indicating the lower folding line 8 as die 52 interacts with a dolly plate 53 disposed under the endless conveyor belt 17.
- the dies 51 and 52 are suspended on a common plate 54 which is actuated by an actuator 55.
- Fig. 9 shows a glue application unit 70.
- the unit 70 includes a frame 71 which is suspended pivotably about a journal 72.
- the frame 71 includes a translational displaceable gluing unit 73 having a slotted glue nozzle 74 for hotmelt adhesive.
- the unit 70 is provided with sensors so that it only can give off adhesive if a packaging is present in the work station concerned.
- the frame 71 is swung in against the packaging item.
- the glue application is activated, and simultaneously there is performed a translational displacement of the unit 73 in relation to the frame 71 until desired width of the adhesive strip 10 is established.
- Fig. 10 shows the subsequent operation unit 56 which is a folding or winding unit.
- This unit includes a cam guide 57 having a largely circular guide track 58 that interacts with a roller 59.
- a track 58 and a roller 59 are provided at each side of the packaging as seen more clearly in Fig. 11.
- the rollers are activated by a piston 60 when a packaging is situated in the operation unit Together with each of the rollers there is a check plate 61 engaging the storage compartment 4 of the filled packaging.
- the storage compartment is pivoted through an angle when the roller 59 is displaced up along the track 58 to the position shown in Fig. 11. In this position, the packaging will be folded up to contact against the flap 2 which will be supported on the endless conveyor belt 17 via a centre section 66 (see Fig. 1). Subsequently, a piston will press the upper flap area 67 from above (see Fig. 1) down over the rear wall 7.
- the packaging is closed as the adhesive strip 10 is applied to the flap 2 in the operation unit 70 between the embossing unit 50 and the winding unit 56.
- the rollers 59 are returned by actuating the piston 60 in the opposite direction.
- the plates 61 are disposed with a certain pivoting ability in relation to support brackets 62. At the beginning retraction, the plates 61 will therefore pivot outwards, away from the packaging, due to the support brackets 62 and the curvature on the track 58. Thus there is no risk that the plates 61 will displace the packaging when moving back.
- Fig. 12 illustrates a laying unit 63 that includes a conveyor belt 64 on which packagings are falling down when they are in the last station shown by 65, and when the vacuum from this vacuum chamber 14 is released. Thus it is possible to let the packaging fall down on the conveyor belt 64 for subsequent handling, packaging, etc.
- Fig. 12 clearly illustrates one of the reversing rollers 18 for the endless conveyor belt 17. It is seen that it is a toothed reversing roller that interacts with tooth gearing on the endless conveyor belt 17, thereby ensuring that.the endless conveyor belt 17 is always correctly indexed.
- one or more of the shown stations above the endless conveyor belt 17 may be provided with retainer plates that are connected with the vacuum source.
- the upper area 63 on the flap may be sucked firmly into abutment against such a retainer plate for better fixation of the flap.
- This may particularly be advantageous in the operation unit 70 for applying the adhesive strip 10, which is effected at the outermost part of the flap 2.
- the apparatus will be provided with sensors ensuring that the filling duct is not activated and not emitting a flow of material if a packaging is not disposed correctly in the filling station.
- the other operation units are safeguarded against malfunctioning.
- the operation unit for adhesive application is safeguarded by a sensor registering whether a packaging is present and blocking the adhesive application if there is no packaging in the operation unit.
- Application of adhesive on a dolly or retainer plate will result in subsequent functional failure as one is risking that subsequent packagings are now adhering to the retainer plate in such an operation unit.
- the operation units are secured so that they face an operator situated at the side of the apparatus.
- the mounting is made to the frame 25 of the apparatus (see e.g. Fig. 5) by means of a fitting 68 which is screwed on to the apparatus frame 25 by means of a bolt 69.
- Several bolts may be used as well as the operation unit may also be fastened at the underside of the apparatus frame 25.
- FIG. 3 Furthermore is seen from Fig. 3 that an apparatus with 9 stations in all have been provided and in which a operational unit is possible to be placed.
- a spring steel pressing against the endless conveyor belt 17 in order thereby to block the openings 21 in an aperture pattern 20 where the endless conveyor belt 17 is in a free work station, and where simultaneously there may occur a situation without packaging disposed opposite to such aperture pattern 20.
- a plate When such a plate is used, one will avoid noise problems that may occur due to air flow through the openings 21 of the endless conveyor belt 17.
- the operation unit 75 shown in Fig. 13 constitutes an apparatus intended for labelling and including a magazine 76 containing labels 77 and means 78 for transferring labels 77 by using a suction cup 79 for a packaging 1 in the shape of a folded tobacco pouch which in vertical position is supported on the vacumm endless conveyor belt 17 17.
- the operation unit 75 is shaped as a modular unit.
- the labels 77 are provided as a horizontal stack 80 with a longitudinal direction coincident with the longitudinal direction 81 of the magazine 76. At one end, the stack 80 is supported by a block 82 and at its other end held against retainer surfaces 83 which are more clearly illustrated in Fig. 14.
- the retainer surfaces 83 are formed by circular discs with a diameter being larger than the diameter of circular guide rods 84 which support side surfaces 85 on the labels. Only one of the side faces 85 is illustrated in Fig. 14, and corresponding guide rods 84 will be provided at the opposite side of the stack.
- the block 82 is disposed at an upper course 86 of a conveyor belt 87 which is passed around reversing rollers 88.
- the upper course of the conveyor belt 87 is conveyed in direction of arrow 89 whereby the block 82 presses against the rearmost label 77' in the stack 80.
- the foremost label 77" (see Fig. 14) is pressed against the retainer surfaces 83.
- the conveyor bells 87 are conveyed intermittently by using a first piston device 90 which via an arm 91 is in contact with the left reversing roller 88 and is advancing this intermittently as a consequence of activation of the first piston device 90. Activation is occurring synchronously with giving off labels from the magazine 76 for holding the foremost label 77' in contact against the retainer surfaces 83 with largely constant pressure.
- the block 82 is placed loosely on upper course 86 of the conveyor belt 87 and is conveyed only by the frictional engagement between the block and the belt 87.
- the block will usually be made of metal and have a weight ensuring continuous contact against the stack 80.
- the transfer means include, as previously mentioned, a suction cup 79. This is placed in a bracket 92 which is rotatable about a vertical axis 93. In Fig. 13, the bracket 92 is shown in two positions. These are of course not appearing at the same time and are only indicated in Fig.13 for illustrative reasons.
- the bracket 92 is thus, as indicated with arrow 96, rotatable about its vertical axis 93 for aligning the suction cup 79 with the label stack and with the packaging 1, respectively.
- the second piston device 94 can be used for displacing the suction cup 79 into engagement with the outermost label 77' in a secured stack, it is preferred that the stack is mounted on a support 97 which via a third piston device 98 is displaceable in direction of the arrow 99 for bringing the foremost label 77' into engagement with a secured suction cup 79.
- Labels 77 are provided in the magazine 76, and the block 82 is placed in abutment against the rearmost label 77' in the stack.
- the apparatus is activated, and when a first, outermost label 77" in the stack is to be taken out, the stack 80 will be displaced by activation of the third piston device 98.
- the adhesive on the label may be activated or adhesive may be applied.
- the second piston device 94 When a packaging 1 is brought in position opposite to the label 77, the second piston device 94 is activated again so that the label 77 is pressed against the packaging 1.
- the first piston device 90 is activated so that the label stack 80 is constantly held against the retainer surfaces 83 with a largely constant pressure.
- the pressure is slackened slightly at the time of taking out the foremost label from the stack for controlling the pressure existing at the taking out of the label, independently of the label size.
