DK 97 00182 U3DK 97 00182 U3

Den foreliggende frembringelse vedrører rotationsprægning eller -stansning, specielt rotationsprægning eller -stansning af papir eller plastfolie såsom baneformet materiale til fremstilling af eksempelvis etiketter, mærkater, plastre eller lignende. Ved rotationsprægningen eller -stansningen foretages der 5 en bearbejdning eller bortskæring af en del af det arkformede eller baneformede materiale, der typisk kan bestå af et bagpapir eller slippapir i form af en kontinuerlig silikoneret papirbane, der understøtter en papir- eller plastfoliebane, hvis ene side vendende mod bagpapiret er påført et klæbemiddel. I denne sammenhæng benyttes papir og plast som synonymer og som generiske betegnelser for 10 ark- eller baneformet materiale, herunder woven og non-woven plastfilm, der er egnet til kold- eller varmeprægning eller kold- eller varmestansning til frembringelse af specifikke individuelle eller sammenhængende stykker af det arkformede eller baneformede materiale, der som anført ovenfor kan udgøres af en sammensat bane, en lamineret bane eller en bane omfattende et enkelt papir-15 eller plastark såsom en enkelt plastfolie.The present invention relates to rotational embossing or stamping, in particular rotational embossing or stamping of paper or plastic foil such as web-shaped material for the manufacture of, for example, labels, labels, patches or the like. In the rotational embossing or punching, a machining or cutting of a portion of the sheet or web-shaped material, which may typically consist of a backing or release paper in the form of a continuous silicone paper web supporting a paper or plastic foil web, is provided. facing the backing paper, an adhesive is applied. In this context, paper and plastic are used as synonyms and as generic terms for 10 sheet or web-shaped materials, including woven and non-woven plastic films suitable for cold or heat embossing or cold or heat stamping to produce specific individual or contiguous pieces. of the sheet-shaped or web-shaped material, which, as stated above, may be a composite web, a laminated web or a web comprising a single paper or plastic sheet such as a single plastic film.

Ved fremstilling af eksempelvis mærkater eller etiketter ud fra en lamineret papirbane omfattende en papirbane, hvis ene side er påført et klæbemiddel, og som understøttes af en bane af silikoneret bagpapir, foretages der en præcis 20 gennemskæring af papirbanen fra oversiden af denne mod bagpapirbanen, idet gennemskæringen skal være så nøjagtigt justeret, at kun papirbanen gennemskæres, uden at bagpapirbanen skæres eller læderes. Skæringen skal følgelig være så præcis, at rotationspræge- eller stanseværktøjets skærende æg når gennem papirbanen, men kun når ind i klæbemiddellaget påført papirbanen uden 25 at berøre, dvs. skærer eller læderer bagpapirbanen. Ved en rotationsprægning eller -stansning af denne art er produktionsvoluminet meget stort, eksempelvis adskillige tusinde mærkater eller etiketter produceret pr. time. Rotationshastigheden er følgelig også ganske betragtelig, ligesom den slitage, som rotationsværktøjerne er udsat for, er betydelig. I talrige kendte produktionsanlæg af den 30 her omhandlede art, dvs. rotationspræge-, stanse- eller skæreværktøjer, medfører den høje produktionshastighed sammenholdt med den nødvendige meget nøjagtige præge-, stanse- eller skærenøjagtighed, at værktøjerne må udskiftes eller modificeres ganske hyppigt, eksempelvis efter en arbejdsdag eller et begrænset antal arbejdsdage, dvs. i løbet af en produktionstid på 5-10 timer.For example, in the manufacture of labels or labels from a laminated paper web comprising a paper web, one side of which is applied with an adhesive and supported by a web of silicone backed paper, a precise cutting of the paper web from the top thereof to the backing paper web is made. the intersection must be so precisely adjusted that only the paper web is cut without cutting or leather the backing web. Accordingly, the cutting must be so precise that the cutting edge of the embossing or punching tool reaches through the paper web, but only reaches into the adhesive layer applied to the paper web without touching, ie. cut or leather the backing paper web. In a rotational embossing or punching of this kind, the volume of production is very large, for example several thousand labels or labels produced per hour. Consequently, the rotational speed is also quite considerable, as is the wear and tear to which the rotary tools are exposed. In numerous known production plants of the kind referred to herein, viz. rotary embossing, punching or cutting tools, the high production rate compared to the required very accurate stamping, punching or cutting accuracy means that the tools must be replaced or modified quite frequently, for example after a working day or a limited number of working days, ie. during a production time of 5-10 hours.

Denne nødvendige udskiftning af de skærende værktøjer medfører for det første en rejustering af hele produktionsmaskineriet, for det andet en afbrydelse af pro- 35 2 DK 97 00182 U3 duktionen, dvs. en standsning af produktionen med deraf følgende økonomiske tab. Der er følgelig et ønske om - og et behov for - tilvejebringelse af valsesæt til brug ved rotationsprægning eller -stansning af arkformet, fortrinsvis baneformet materiale såsom papir eller plastfolie, hvilket valsesæt muliggør brug af 5 valsesættet i et længere tidsrum end de hidtil kendte valsesæt, der som følge af slitage må udskiftes hyppigt.This necessary replacement of the cutting tools leads, firstly, to a readjustment of the entire production machinery, secondly, interruption of production, ie. a halt to production with consequent financial losses. Accordingly, there is a desire - and a need - to provide roll sets for use in rotary embossing or punching of sheet-shaped, preferably web-shaped material such as paper or plastic film, which roll set allows for use of the roll set for a longer period of time than the known rolling sets, which due to wear must be replaced frequently.

Det ovenfor angivne ønske eller behov opfyldes med et valsesæt ifølge den foreliggende frembringelse til brug ved rotationsprægning 10 eller -stansning af arkformet, fortrinsvis baneformet materiale såsom papir eller plastfolie, fx til fremstilling af etiketter, mærkater eller lignende og omfattende en præge- eller stansevalse, der er indrettet til at blive drevet i synkronisme med det arkformede materiale, og som på sin ydre cylindriske flade har periferisk udformede prægninger eller profileringer til frembringelse af prægningen eller 15 stansningen i det arkformede materiale, samt en modholdervalse, der er indrettet til at samvirke med præge- eller stansevalsen til fremføring af det arkformede materiale mellem præge- eller stansevalsen og modholdervalsen og til indspænding af det arkformede materiale mellem præge- eller stansevalsen og modholdervalsen, idet der mellem præge- eller stansevalsen og modholdervalsen er 20 defineret et specifikt mellemrum, i hvilket mellemrum prægningen eller stansningen udføres, hvilket valsesæt i overensstemmelse med frembringelsen er ejendommeligt ved, at i det mindste den ene af de to valser, dvs. præge- eller stansevalsen eller modholdervalsen, er lejret excentrisk på en i forhold til den anden valse fast aksel.The above-mentioned wish or need is met with a roller set according to the present invention for use in rotating embossing 10 or stamping sheet-shaped, preferably web-shaped material such as paper or plastic foil, for example for making labels, labels or the like and comprising an embossing or punching roll, adapted to be driven in synchronism with the sheet-shaped material and having on its outer cylindrical surface circumferentially formed embossings or profiling to produce the embossing or punching of the sheet-shaped material, and a retainer roller adapted to cooperate with the embossing or punching roll for advancing the sheet-shaped material between the embossing or punching roll and the retaining roll and for clamping the sheet-like material between the embossing or punching roll and the retaining roll, a specific space being defined between the embossing or punching roll and between the embossing or punching is carried out, which roll set according to the production is peculiar in that at least one of the two rollers, ie. the embossing or punching roll or the holding roll, is mounted eccentrically on one relative to the other roller fixed shaft.

Ved monteringen af de to samvirkende valser på en sådan måde, at den ene valse er monteret excentrisk på en i forhold til den anden valse fast aksel muliggør, at den excentrisk lejrede valse kan repositioneres ved drejning af den faste aksel således, at den excentrisk lejrede valse føres tættere mod eller bort fra den anden 30 valse, idet den excentriske lejring netop medfører, at den excentrisk lejrede aksel enten ved drejning af den faste aksel føres mod eller bort fra den anden valse. Denne excentriske lejring muliggør følgelig en justering af den indbyrdes placering af de to samvirkende valser og muliggør dermed en justering af den excentrisk lejrede valses placering i forhold til den anden valse således, at even-35 tuel slitage, der medfører en reduktion af det specifikke mellemrum mellem de to valser, udkompenseres, ligesom en forøgelse af det specifikke mellemrum mellem de to valser udkompenseres ved drejning af den faste aksel i den mod- 3 DK 97 00182 U3 satte retning.When mounting the two co-operating rollers in such a way that one roller is mounted eccentrically on a fixed shaft relative to the other roller, the eccentrically mounted roller can be repositioned by turning the fixed shaft so that the eccentrically mounted roller is moved closer to or away from the second roller, the eccentric bearing precisely causing the eccentrically bearing shaft to be moved toward or away from the second roller either by rotation of the fixed shaft. Accordingly, this eccentric bearing allows an adjustment of the mutual positioning of the two cooperating rollers, and thus allows an adjustment of the position of the eccentric bearing roll relative to the second roller, so that any wear which results in a reduction of the specific gap between the two rollers is compensated, just as an increase in the specific gap between the two rollers is compensated by turning the fixed shaft in the opposite direction.

De to valser i valsesættet, dvs. præge- eller stansevalsen og modholdervalsen kan, afhængigt af det aktuelle produktionsmaskineri, udgøre den excentrisk lejrede valse, idet det i overensstemmelse med frembringelsen også er muligt, at begge valser er lejret excentrisk på faste aksler. I overensstemmelse med alternative udførelsesformer for valsesættet ifølge den foreliggende frembringelse er modholdervalsen lejret excentrisk ved hjælp af kugle- eller rullelejer på en i forhold til præge- eller stansevalsen fast aksel, eller alternativt er præge- eller stansevalsen lejret excentrisk ved hjælp af kugle- eller rullelejer på en i forhold til modholdervalsen fast aksel. Alternativt er både præge- eller stansevalsen eller modholdervalsen lejret excentrisk ved hjælp af kugle- eller rullelejer på respektive faste aksler.The two rollers in the roll set, ie. depending on the actual production machinery, the embossing or punching roll and the holding roller may constitute the eccentrically mounted roller, in accordance with the production it is also possible that both rolls are mounted eccentrically on fixed shafts. In accordance with alternative embodiments of the roller set of the present invention, the retainer roller is mounted eccentrically by means of ball or roller bearings on a fixed shaft relative to the embossing or punching roller, or alternatively, the embossing or punching roller is mounted eccentrically by ball or roller bearings. on a fixed shaft in relation to the counter support roller. Alternatively, both the embossing or punching roll or the holding roller are mounted eccentrically by means of ball or roller bearings on respective fixed shafts.

Forudsat, at modholdervalsen udgør den excentrisk lejrede aksel, har modholdervalsen fortrinsvis lejeringe, der er lejret koaksialt på den nævnte faste aksel, på hvilken modholdervalsen er lejret excentrisk, hvilke lejeringe fortrinsvis er monteret ved modstående ender af modholdervalsen og tjener til at samvirke med tilsvarende lejeringe eller bæreringe på præge- eller stansevalsen til fastlæggelse af det omtalte specifikke mellemrum mellem de to valser. Andre alternative monteringer af de to samvirkende valser kan også med fordel implementeres i overensstemmelse med frembringelsens lære, dvs. med den ene af de to valser lejret excentrisk for dermed at muliggøre en kompensation for slitage på præge- eller stanseværktøjet eller slitage på lejer for eliminering af den hidtil hyppige udskiftning af værktøjsdelene.Provided that the retainer roll constitutes the eccentrically bearing shaft, the retainer roll preferably has bearings coaxially mounted on said fixed shaft, on which the retainer roll is mounted eccentrically, which bearings are preferably mounted at opposite ends of the retainer roll and serve to cooperate or bearing rings on the embossing or punching roll to determine the said specific gap between the two rollers. Other alternative mountings of the two co-operating rollers can also be advantageously implemented in accordance with the teachings of the production, viz. with one of the two rollers mounted eccentrically so as to allow compensation for wear on the embossing or punching tool or wear on bearings to eliminate the frequent replacement of the tool parts.

Til frembringelse af den omtalte rotation af præge- eller stansevalsen kan denne være udformet med rem- eller tandhjul til samvirken med et drivende rem- eller et drivende tandhjul, der igen drives af en motor. Alternativt eller supplerende kan modholdervalsen være udformet med rem- eller tandhjul til samvirken med rem- eller tandhjulet på præge- eller stansevalsen til overførsel af rotationsbevægelse til eller fra præge- eller stansevalsen.In order to produce the said rotation of the embossing or punching roll it may be formed with belt or sprockets for cooperation with a driving belt or driving sprocket driven in turn by a motor. Alternatively or additionally, the retainer roller may be formed with belt or sprocket for cooperating with the belt or sprocket on the embossing or punching roller for transferring rotational movement to or from the embossing or punching roll.

Det ovenfor angivne ønske eller behov opfyldes også med en valse ifølge frembringelsen til et valsesæt, hvilken valse i overensstemmelse med frembringelsen udgør enten en modholdervalse eller en præge- eller stansevalse og er lejret i overensstemmelse med frembringelsens lære excentrisk på en i forhold til den 4 DK 97 00182 U3 anden valse fast aksel.The above-mentioned wish or need is also met by a roller according to the manufacture of a roller set, which roller according to the production constitutes either a retainer roller or an embossing or punching roller and is stored according to the teaching of the production eccentrically in relation to the 4 DK 97 00182 U3 second roller fixed shaft.

Det ovenfor angivne ønske eller behov opfyldes også med en maskine ifølge frembringelsen og med en præge- eller stansevalse og en modholdervalse, af 5 hvilke i det mindste den ene i overensstemmelse med frembringelsens lære er lejret excentrisk på en i forhold til den anden valse fast aksel.The above-mentioned wish or need is also met by a machine according to the invention and with an embossing or punching roll and a holding roller, of which at least one according to the teachings of the invention is mounted eccentric on a fixed shaft relative to the other roller. .

Frembringelsen vil i det følgende blive nærmere forklaret under henvisning til tegningen, på hvilken 10The invention will be explained in more detail below with reference to the drawing, in which:

20 I Fig. 1 er under ét med henvisningsbetegnelsen 10 angivet en skærestation i en maskine til fremstilling af mærkater eller etiketter. Skærestationen kan ækvivalent udgøre en præge- eller stansestation, i hvilken der foretages en bearbejdning ved prægning eller stansning af arkformet, specielt baneformet papir eller plast-25 materiale, eller kombinationer af sådanne materialer, eksempelvis laminerede papir/plastfolier. Fra en forrådsrulle 12, der er monteret på en aksel 14, afgives en kontinuerlig bane 16 af ark eller baneformet materiale, der er ført omkring en første rulle 18 og neden om en anden rulle 20. Materialet i banen 16 udgøres af et laminat af et bagpapir, som udgør en slipfolie, såsom en silikoneret papirfolie, 30 til hvilken der er lamineret en papirbane, som på den mod slippapiret vendende side er påført et klæbemiddel.In FIG. 1, a reference station 10 together with a reference station is indicated in a machine for making labels or labels. The cutting station may equivalently constitute an embossing or punching station in which a machining is done by embossing or punching sheet-shaped, especially web-shaped paper or plastic material, or combinations of such materials, for example, laminated paper / plastic sheets. From a stock roll 12 mounted on a shaft 14, a continuous web 16 of sheet or web material is passed around a first roll 18 and below a second roll 20. The material in the web 16 is constituted by a laminate of a backing paper which constitutes a release film, such as a siliconized paper film, to which is laminated a paper web which is applied to the adhesive facing side of the release paper.

Banen 16 er ført op mellem to valser, en nederste modholdervalse eller modtryksvalse 22, og en øverste præge- eller stansevalse 24, som udgør et skære-35 værktøj eller en skærevalse. De to valser 22 og 24 er lejret i et stel i den maskine, i hvilken også rullen 12 er ophængt monteret på akslen 14. Modholdervalsen 22 er, som det fremgår af Fig. 1, udformet med et tandremshjul 26, der er mon- 5 DK 97 00182 U3 teret på en aksel 28, som udgør en fast, dvs. ikke-roterende aksel i forhold til maskinens stel. Tandremshjulet 26 er således lejret i et kugle- eller rulleleje på akslen 28 og tjener til at overføre en rotationsbevægelse frembragt af en motor 30, som via et tandremsdrivhjul 32 driver en tandrem 34. På den faste aksel 28 er endvidere lejret et tandhjul 36, der er fast koblet til tandremshjulet 28 og samvirker med et tandhjul 38 på præge- eller stansevalsen 24. Præge- eller stansevalsen 24 udgør en sammenhængende konstruktion, der definerer roterende eller medløbende akseltappe 40 og 42, der er monteret i kugle- eller rullelejer i maskinens stel. Tandhjulet 38 er således fast forbundet med præge- eller stansevalsen 24 og roterer sammen med akseltappene 40 og 42. Præge- eller stansevalsen 42 har, som det fremgår af Fig. 1, to lejeringe 44 og 46, der samvirker med modstående lejeringe 48 og 50 på modholdervalsen 22, hvilke lejeringe 48 og 50 er lejret koaksialt på akslen 28 og fritløbende i forhold til såvel tandremshjulet 26 som det hermed fast forbundne tandhjul 36. Mellem lejeringene 48 og 50 er aksialt lejret en modholdercylinder eller modtrykscylinder 52, der kan rotere omkring en akse, der er forskudt i forhold til lejeaksen for lejeringene 48 og 50 samt tandhjulet 36 og tandremshjulet 26. Denne excentriske lejring af mod-holdercylinderen 52 frembringer en justeringsmulighed til kompensation for slitage på lejeringene 44, 46, 48 og 50, samt slitage på et skærende værktøj 54, der er udformet på den midterste cylindriske del af præge- eller stanse valsen 24. Dette skæreværktøj tjener til at bortskære en del af papirlaget af laminatbanen 16, således som det fremgår af Fig. 1, for dermed at udskære individuelle etiketter eller mærkater 56, der understøttes på den bagved liggende, kontinuerlige slippapirbane 58.The web 16 is guided between two rollers, a lower retaining roller or counterpressure roller 22, and a top embossing or punching roller 24 which constitutes a cutting tool or cutting roller. The two rollers 22 and 24 are mounted in a frame in the machine in which also the roller 12 is mounted mounted on the shaft 14. The counter-roll 22 is as shown in FIG. 1, provided with a gear belt wheel 26 mounted on a shaft 28 which forms a fixed, i.e. non-rotating shaft relative to the machine frame. Thus, the gear belt wheel 26 is mounted in a ball or roller bearing on the shaft 28 and serves to transmit a rotational movement produced by a motor 30 which drives a toothed belt 34 via a toothed belt drive wheel 34. A gear 36 is further mounted on the fixed shaft 28. is fixedly coupled to the gear belt wheel 28 and cooperates with a gear 38 on the embossing or punching roll 24. The embossing or punching roll 24 is a continuous structure defining rotary or concurrent shaft pins 40 and 42 mounted in ball or roller bearings in the machine frame . The gear 38 is thus firmly connected to the embossing or punching roll 24 and rotating together with the shaft pins 40 and 42. The embossing or punching roll 42 has, as can be seen in FIG. 1, two bearings 44 and 46 which cooperate with opposing bearings 48 and 50 on the counter roll 22, which bearings 48 and 50 are coaxially mounted on shaft 28 and freely in relation to both the gear belt wheel 26 and the associated sprockets 36. Between the bearings 48 and 50 are axially mounted a retaining cylinder or counterpressure cylinder 52 which can rotate about an axis displaced relative to the bearing axis of the bearing rings 48 and 50, and the sprocket 36 and the timing belt 26. This eccentric bearing of the retaining cylinder 52 provides an adjustment option for compensation. for wear on the bearing rings 44, 46, 48 and 50, as well as wear on a cutting tool 54 formed on the middle cylindrical portion of the embossing or punching roll 24. This cutting tool serves to cut away part of the paper layer of the laminate web 16, as shown in FIG. 1, so as to cut individual labels or labels 56 supported on the continuous continuous web paper 58.

Som omtalt ovenfor giver den excentriske lejring af modholdercylinderen 52 i forhold til præge- eller stansevalsen 24 mulighed for kompensation for eventuelle variationer i placeringen af præge- eller stansevalsen 24's præge- eller skæreværktøj 54 i forhold til modholder- eller modtrykscylinderen 52. I Fig. 2 og 3 er dette specielle træk ved frembringelsen illustreret mere detaljeret.As discussed above, the eccentric bearing of the barrel cylinder 52 relative to the embossing or punching roll 24 allows for compensation for any variation in the location of the punching or cutting tool 24's embossing or cutting tool 54 relative to the barrel or backpressure cylinder 52. In FIG. 2 and 3, this particular feature of the production is illustrated in more detail.

I Fig. 2 er vist de to valser, modholdervalsen 22 og præge- eller stansevalsen 24, der er placeret ud for hinanden via de samvirkende lejeringe såsom lejeringen 48 på præge- eller stansevalsen 22 og lejeringen 44 på præge- eller stansevalsen 24. Til frembringelse af en nøjagtig positionering af skæreværktøjet 54 i forhold til den ud for skæreværktøjet 54 placerede modholdercylinder 52 tjener et pressehjul 60, der er placeret over, dvs. fysisk hvilende på lejeringen 44. Som 6 DK 97 00182 U3 det fremgår af Fig. 2, definerer en nederste kant 62 af skæreværktøjet 54 en lille, men specifik afstand til ydersiden af modholdercylinderen 52, i hvilket mellemrum det baneformede materiale 16 indføres til frembringelse af prægningen eller stansningen ved hjælp af skæreværktøjet 54. Som følge af slitage på lejeringene 44 og 48 eller på skæreværktøjet 54 kan afstanden mellem den skærende æg 62 på skæreværktøjet 54 fra yderfladen af modholdercylinderen 52 enten aftage eller tiltage, og til kompensation for denne afstandsvariation er modholdercylinderen 52, som vist overdrevet i Fig. 2, lejret excentrisk i forhold til den stationære eller ikke-roterende aksel 28. I Fig. 2 er således vist den centrale del 64 af akslen 28, hvilken centrale del frembringer den excentriske lejring af modholdercylinderen 52. I Fig. 2 angiver henvisningsbetegnelsen 66 en lås, som låser eller fikserer den faste eller ikke-roterende aksel 28 i forhold til maskinens stel og dermed positionerer den excentrisk lejrede modholdercylinder 52 i den viste stilling. Ved drejning af akslen 28 1800 fra den i Fig. 2 viste stilling føres den centrale del 64 af akslen 28 til en stilling angivet med punkteret linie 68 i Fig. 2, i hvilken stilling den excentrisk lejrede modholdercylinder 52 er ført længst muligt frem mod præge- eller stansevalsen 24.In FIG. 2, the two rollers, the retainer roll 22 and the embossing or punching roll 24, are placed next to each other via the cooperating alloys such as the bearing ring 48 on the embossing or punching roll 22 and the bearing ring 44 on the embossing or punching roll 24. To produce an accurate positioning of the cutting tool 54 relative to the retainer cylinder 52 positioned next to the cutting tool 54 serves a pressing wheel 60 positioned above, i.e. physically resting on the bearing ring 44. As shown in FIG. 2, a lower edge 62 of the cutting tool 54 defines a small but specific distance to the outside of the retaining cylinder 52, in which space the web-shaped material 16 is introduced to produce the embossing or punching by the cutting tool 54. As a result of wear on the bearing rings 44 and 48 or on the cutting tool 54, the distance between the cutting egg 62 on the cutting tool 54 from the outer surface of the barrel cylinder 52 can either decrease or increase, and to compensate for this distance variation, the barrel barrel 52, as shown in FIG. 2, mounted eccentrically relative to the stationary or non-rotating shaft 28. In FIG. 2, the central portion 64 of the shaft 28 is thus shown, which central portion produces the eccentric bearing of the barrel cylinder 52. In FIG. 2, the reference numeral 66 denotes a lock which locks or fixes the fixed or non-rotating shaft 28 relative to the frame of the machine and thus positions the eccentrically mounted counter-barrel cylinder 52 in the position shown. By turning the shaft 28 1800 from the one shown in FIG. 2, the central portion 64 of shaft 28 is guided to a position indicated by dotted line 68 in FIG. 2, in which position the eccentrically mounted retainer cylinder 52 is advanced as far as possible towards the embossing or punching roll 24.

I Fig. 3 er denne justeringsmulighed for den excentrisk lejrede modholdercylinder 52 anskueliggjort, idet der øverst i Fig. 3 er vist et snit gennem præge- eller stansevalsen 24 visende skæreværktøjet 54 og den medløbende akseltap 40, der i Fig. 2 er lejret i en lejebøsning 74 i form af et kugle- eller rulleleje. Nederst i Fig. 3 er tilsvarende vist et snit gennem præge- eller stansecylinderen 22 visende den excentriske justeringsmulighed for positioneringen af modholdercylinderen 52 i forhold til skæreværktøjet 54 på præge- eller stansecylinderen 24. Med fuldt optrukket linie er således vist den ligeledes i Fig. 2 viste stilling af modholdercylinderen 52, medens der med punkteret linie er vist den maksimalt fremrykkede stilling for modholdercylinderen 52 i forhold til præge- eller stansevalsen 24, svarende til de i Fig. 2 viste punkterede linier 68. I Fig. 3 er den maksimalt fremrykkede position for ydersiden af modholdercylinderen 22 angivet med henvisningsbetegnelsen 70, medens den tilsvarende placering for den centrale eller midterste del 64 af akslen 28 er angivet med henvisningsbetegnelsen 72.In FIG. 3, this adjustment option for the eccentrically mounted counter-barrel cylinder 52 is illustrated, at the top of FIG. 3 is a section through the embossing or punching roll 24 showing the cutting tool 54 and the associated shaft pin 40 shown in FIG. 2 is mounted in a bearing bush 74 in the form of a ball or roller bearing. At the bottom of FIG. 3 is a sectional view through the embossing or punching cylinder 22 showing the eccentric adjustment possibility for the positioning of the counter-holding cylinder 52 relative to the cutting tool 54 on the embossing or punching cylinder 24. Thus, with a fully drawn line, it is also shown in FIG. 2 shows the position of the barrel barrel 52, while the dashed line shows the maximum forward position of the barrel barrel 52 relative to the embossing or punching roll 24, similar to those in FIG. 2 shows dashed lines 68. In FIG. 3, the maximum forward position of the outside of the counter-barrel cylinder 22 is indicated by the reference numeral 70, while the corresponding location for the central or middle portion 64 of the shaft 28 is indicated by the reference numeral 72.
