Definitions
- the invention relates to a method and a device for the stripping of laminated film blanks which are provided with incisions in a cover film glued to a backing adhesive layer with a backing paper, which cutouts form an advertising lettering or advertising graphic designed for self-adhesive attachment to an advertising surface.
- the film material used in the production of so-called film fonts, cut to a sheet or piece size usually consists of a very thin and therefore extremely flexible, mostly rolled or cast and therefore in any case also shrinkable plastic film, which is used as a cover film over a back Pressure sensitive adhesive layer is laminated onto a carrier paper.
- shrinkable plastic film which is used as a cover film over a back Pressure sensitive adhesive layer is laminated onto a carrier paper.
- the invention has for its object to provide a method and an apparatus for the stripping of laminated film blanks, in which the peeling the remainder of the film from the backing paper with the greatest possible protection of the advertising lettering or advertising graphics remaining on the backing paper can be carried out mechanically with simple means and thus less costly.
- the device designed for stripping laminated film blanks has a transport table 2 held by a stand 1.
- the transport table 2 is provided for a support of the sheet blanks 3 having a sheet or piece size and their successive transport in a predetermined transport direction 4.
- Each film blank 3 consists of a cover film, which is laminated onto a backing paper via a pressure-sensitive adhesive layer on the back.
- the cover film is provided with cuts which form an advertising lettering or advertising graphic which remains on the backing paper when the film remainder of the cover film adjacent to the cuts is pulled off the backing paper.
- the removal of the film residue from such laminated film blanks is understood as "stripping" because the advertising lettering or advertising graphics remaining on the backing paper of each film blank is exposed or “stripped” for later self-adhesive attachment to an advertising surface.
- a deflection edge 8 is formed with the tip of an angled guide plate 9, on which the remainder of the film of the cover film is pulled off the carrier paper in cooperation with a transfer device 10. During this “stripping”, the advertising lettering or advertising graphic formed by cutting the cover film remains on the carrier paper, which is removed behind the deflection edge 8 in the predetermined transport direction 4.
- the transfer device 10 is formed with a rubber-elastic pad 11, which is arranged on a transfer carriage 12.
- the transfer carriage 12 is movable along a guide rail 13, which thus defines a transfer direction branched off from the predetermined transport direction 4 on the deflection edge 8, in which the remainder of the film is pulled off the carrier paper of each film blank 3.
- This removal of the film residue from the backing paper is obtained in that the rubber-elastic cushion 11 is initially set in such a position relative to the deflection edge 8 that when a film cut arrives, its cover film comes into contact with the cushion 11 first.
- a brush 8 ' is expediently arranged in the vicinity of the deflection edge 8 which is acted on the cover film of each film blank in such a way that the separation of the film residue from the advertising lettering or advertising graphics is promoted during the removal of the film residue.
- a heat channel 5 ' is expediently arranged in the vicinity of the cutting device 5 in order to achieve shrinkage of the cover film and thus an increase in the cutting width of the incisions forming the advertising lettering or advertising graphics even before the film remnant is removed.
- the transfer device 10 can be moved along the guide rail 13 up to an end position in which the film remainder 15 adhered to the pad 11 with its leading edge region is transferred to a remainder roll 16.
- the transfer is obtained in that the transfer carriage 12, which is shown for this end position with a relative position 12 ', is pivoted about an axis parallel to the axis of rotation of the residual roller 16. Because during this pivoting of the transfer carriage 12, the cushion 11 'is also brought into a changed relative position to the residual roll 16, the film residue 15 with its rear-side pressure-sensitive adhesive layer can thus be placed against the residual roll 16.
- the guide rail 13 is expediently pivotable about an axis 17 provided near the deflection edge 8. This pivotability of the guide rail 13 can, on the other hand, also be used for the secure interaction of the transfer carriage 12 and its cushion 11 with the deflection edge 8 at the time when the film residue 15 is taken over at the branching of the transport direction 4 of the film blanks 3.
- the residual roller 16 is mounted with its axis of rotation 18 on a single link 19 of a link arrangement which also has a second single link 20 for the rotatable mounting of a drive roller 21 which bears against the envelope surface of the residual roller 16.
- the handlebar arrangement formed with the two single-cell cores 19, 20 is mounted on the stand 1 via an axis of rotation 22 of the single-link 20 in such a way that the axis of rotation 18 of the residual roller 16 lies by means of a sliding block 23 along a slot guide 24 which is angularly aligned with the guide rail 13 of the transfer device 10 can be postponed.
- This possibility of displacement of the axis of rotation 18 results in the maintenance of a constant drive ratio for the drive roller 21 with respect to the transport speed of the film blanks 3, taking into account a growing diameter of the residual roll 16 during the filling with the film residues.
- the guide slot 24 is also formed with an open end so that the residual roller 16 can be removed after reaching a predetermined filling level and thus also a predetermined maximum diameter and replaced by an empty new residual roller.
- the various drives, not shown in the drawing, for an operation of the cutting device 5 synchronized with the feeding of the film cuts 3, for the rotation of the feed rollers 6, 7, for the reciprocating movement of the transfer carriage 12, for the optionally provided pivoting movement of the Guide rail 13 and for the drive roller 21 for rotating the residual roller 16 can be given any configuration in conjunction with a suitable control.
- the The device can be supplemented with a suitable collecting device for the carrier papers of the film blanks 3, which are removed behind the branching formed with the deflection edge 8 with the advertising lettering or advertising graphics remaining thereon in the predetermined transport direction 4.
- the collecting device can ultimately also be combined with an application device with which the advertising or advertising graphics are transferred from the carrier papers to individual transfer foils, which are used as aids for the self-adhesive application of the advertising or advertising graphics to an advertising surface.
Abstract
Description
Die Erfindung bezieht sich auf ein Verfahren und eine Vorrichtung zum Entstrippen von laminierten Folienzuschnitten, die in einer über eine rückseitige Haftkleberschicht mit einem Trägerpapier verklebten Deckfolie mit Einschnitten versehen sind, welche eine zum selbstklebenden Anbringen an einer Werbefläche konzipierte Werbeschrift oder Werbegrafik ausbilden.The invention relates to a method and a device for the stripping of laminated film blanks which are provided with incisions in a cover film glued to a backing adhesive layer with a backing paper, which cutouts form an advertising lettering or advertising graphic designed for self-adhesive attachment to an advertising surface.
Das bei der Herstellung von sog. Folienschriften verwendete, auf eine Blatt- bzw. Stückgröße zugeschnittene Folienmaterial besteht in der Regel aus einer sehr dünnen und daher auch äußerst biegeweichen, meistens gewalzten oder auch gegossenen und damit jedenfalls auch schrumpfbaren Kunststoffolie, die als Deckfolie über eine rückseitige Haftkleberschicht auf ein Trägerpapier auflaminiert ist. Mit der meistens farbigen Deckfolie der vereinzelten Folienzuschnitte sind individuell nach bestimmten Vorgaben gestaltete Werbeschriften oder Werbegrafiken ausgebildet, wobei diese Ausbildung häufig computergesteuert mittels spezieller Konturenmesser und vereinzelt auch mit Glühdrähten oder mit einem Laserstrahl durchgeführt wird.The film material used in the production of so-called film fonts, cut to a sheet or piece size, usually consists of a very thin and therefore extremely flexible, mostly rolled or cast and therefore in any case also shrinkable plastic film, which is used as a cover film over a back Pressure sensitive adhesive layer is laminated onto a carrier paper. With the mostly colored cover film of the individual film cuts, advertising lettering or advertising graphics are designed individually according to certain specifications, this training often being computer-controlled using special contour knives and occasionally also using glow wires or a laser beam.
Damit nun eine in der Deckfolie solcher Folienzuschnitte ausgebildete Werbeschrift oder Werbegrafik über die rückseitige Haftkleberschicht an einer Werbefläche angebracht werden kann, muß dafür zuerst der an die Einschnitte der Deckfolie angrenzende Folienrest von dem Trägerpapier jedes Folienzuschnittes abgezogen werden. Dieses Abziehen eines Folienrestes wird nach der Definition als "Entstrippen von laminierten Folienzuschnitten" verstanden, weil damit die Freilegung der auf dem Trägerpapier verbleibenden Werbeschrift oder Werbegrafik erhalten wird.So that an advertising lettering or advertising graphic formed in the cover film of such film cuts can now be attached to an advertising surface via the back pressure-sensitive adhesive layer, the film remainder adjacent to the incisions of the cover film must first be removed from the backing paper of each film cut. This peeling off of a film remnant is understood according to the definition as "stripping of laminated film blanks", because in this way the exposure of the advertising lettering or advertising graphics remaining on the carrier paper is obtained.
Das Entstrippen von laminierten Folienzuschnitten wird bisher ausschließlich manuell durchgeführt. Dabei besteht hauptsächlich die Schwierigkeit, daß der Folienrest an den Einschnitten von den Konturen der auf dem Trägerpapier verbleibenden Werbeschrift oder Werbegrafik sauber abgelöst wird und es also bei diesem Ablösen zu keinem Beschädigen der Konturen kommt, was insbesondere dann leicht geschehen kann, wenn die eine Werbeschrift zusammensetzenden Buchstaben vereinzelt dargestellt sind oder die Werbegrafik eine kompliziertere Schnittkontur mit vielfach wechselnden Richtungsänderungen aufweist. Es muß daher eine entsprechend sorgfältige und ein hohes handwerkliches Geschick erfordernde Handhabung der Folienzuschnitte vorausgesetzt werden, um einwandfreie Werbeschriften und Werbegrafiken zu erhalten, womit in diesem Zusammenhang ohne weiteres erkennbar wird, daß dieses bisher manuell durchgeführte Entstrippen von laminierten Folienzuschnitten sehr kostenintensiv ist.So far, the stripping of laminated film blanks has only been carried out manually. The main problem here is that the film residue at the incisions is cleanly removed from the contours of the advertising lettering or advertising graphics remaining on the backing paper, and so there is no damage to the contours during this removal, which can easily happen, in particular, if the advertising lettering composed letters are shown individually or the advertising graphic has a more complicated cut contour with frequently changing direction changes. It must therefore be assumed that the film blanks must be handled with care and require a high level of manual dexterity to obtain flawless advertising lettering and advertising graphics, with which it is readily apparent in this connection that this previously manual stripping of laminated film cuts is very cost-intensive.
Aus der DE-C-2 212 995 ist ein Verfahren zum Herstellen von Selbstklebeetiketten bekannt, bei dem das Etikettenmaterial zusammen mit einer Klebstoffschicht auf ein Trägerband aufgebracht ist, welches zwischen einer Abwickelwalze und einer Aufwickelwalze durch eine Stanzstation hindurchgeführt wird, in welcher die Etiketten aus dem Etikettenmaterial ausgestanzt werden. Ein bei diesem Ausstanzen der Etiketten gleichzeitig zur Ausbildung kommendes Stanzgitter wird dabei vor dem Aufwickeln des Trägerbandes mit den darauf verbleibenden Etiketten von dem Trägerband unter Vermittlung einer Umlenkwalze abgezogen und auf eine separate Resterolle aufgewickelt. Bei diesem somit kontinuierlich durchführbaren Verfahren bereitet es wegen der größeren Schichtdicke des Etikettenmaterials keine besonderen Schwierigkeiten, das sich bei dem Ausstanzen der Etiketten ausbildende Stanzgitter von dem Trägerband abzuziehen, ohne daß es dabei zu einer Beschädigung dor auf dem Trägerband verbleibenden Etiketten kommt, weil deren als Folge dieser größeren Schichtdicke ebenfalls entsprechend biegesteiferes Verhalten den Trennkräften besser widersteht, die beim Abziehen des Stanzgitters an den Konturen der Etiketten auftreten.From DE-C-2 212 995 a method for producing self-adhesive labels is known, in which the label material is applied together with an adhesive layer to a carrier tape which is passed between an unwinding roller and a winding roller through a punching station, in which the labels are removed the label material are punched out. A punched grid which is formed at the same time during this punching out of the labels is pulled off the carrier tape with the aid of a deflecting roller before winding up the carrier tape with the labels remaining thereon, and is wound up on a separate residual roll. In this method, which can thus be carried out continuously, it is not particularly difficult, because of the greater layer thickness of the label material, to pull off the leadframe forming during the punching out of the labels from the carrier tape without causing damage to the labels remaining on the carrier tape, because of the fact that they are As a result of this greater layer thickness, the correspondingly more rigid behavior better withstands the separating forces which occur on the contours of the labels when the lead frame is pulled off.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zum Entstrippen von laminierten Folienzuschnitten zur Verfügung zu stellen, bei welchen das Abziehen des Folienrestes von dem Trägerpapier unter größtmöglicher Schonung der auf dem Trägerpapier verbleibenden Werbeschrift oder Werbegrafik mit einfachen Mitteln maschinell und damit weniger kostenintensiv durchgeführt werden kann.The invention has for its object to provide a method and an apparatus for the stripping of laminated film blanks, in which the peeling the remainder of the film from the backing paper with the greatest possible protection of the advertising lettering or advertising graphics remaining on the backing paper can be carried out mechanically with simple means and thus less costly.
Diese Aufgabe ist durch die Merkmale des Anspruchs 1 bzw. 5 gelöst.This object is solved by the features of
Ein Ausführungsbeispiel der erfindungsgemäßen Vorrichtung ist in der Zeichnung schematisch dargestellt und wird nachfolgend näher erläutert.An embodiment of the device according to the invention is shown schematically in the drawing and is explained in more detail below.
Die zum Entstrippen von laminierten Folienzuschnitten konzipierte Vorrichtung weist einen durch einen Ständer 1 gehaltenen Transporttisch 2 auf. Der Transporttisch 2 ist für eine Auflage der eine Blatt- bzw. Stückgröße aufweisenden Folienzuschnitte 3 und deren aufeinanderfolgenden Transport in einer vorgegebenen Transportrichtung 4 vorgesehen. Jeder Folienzuschnitt 3 besteht aus einer Deckfolie, die über eine rückseitige Haftkleberschicht auf ein Trägerpapier auflaminiert ist. Die Deckfolie ist mit Einschnitten versehen, welche eine Werbeschrift oder Werbegrafik ausbilden, die auf dem Trägerpapier verbleibt, wenn der an die Einschnitte angrenzende Folienrest der Deckfolie von dem Trägerpapier abgezogen wird. Das Abziehen des Folienrestes von solchen laminierten Folienzuschnitten wird nach der Definition als "Entstrippen" verstanden, weil damit die auf dem Trägerpapier jedes Folienzuschnitts verbleibende Werbeschrift oder Werbegrafik für ein späteres selbstklebendes Anbringen an einer Werbefläche freigelegt bzw. "entstrippt" wird.The device designed for stripping laminated film blanks has a transport table 2 held by a stand 1. The transport table 2 is provided for a support of the sheet blanks 3 having a sheet or piece size and their successive transport in a predetermined transport direction 4. Each film blank 3 consists of a cover film, which is laminated onto a backing paper via a pressure-sensitive adhesive layer on the back. The cover film is provided with cuts which form an advertising lettering or advertising graphic which remains on the backing paper when the film remainder of the cover film adjacent to the cuts is pulled off the backing paper. The removal of the film residue from such laminated film blanks is understood as "stripping" because the advertising lettering or advertising graphics remaining on the backing paper of each film blank is exposed or "stripped" for later self-adhesive attachment to an advertising surface.
Um ein einfaches Abziehen des Folienrestes von dem Trägerpapier jedes Folienzuschnittes 3 zu ermöglichen, wird zunächst dessen vorlaufende Kante 3' mittels einer Schneideinrichtung 5 zugeschnitten. Der Zuschnitt wird mit einem stumpfen Winkel schräg zu der Transportrichtung 4 ausgeführt, sodaß die Oberseite der Deckfolie in der Transportrichtung nach vorne weiter vorsteht als die auf dem Transporttisch 2 aufliegende Unterseite des Trägerpapiers. Nach diesem schrägen Zuschnitt der vorlaufenden Kante 3' wird der Folienzuschnitt 3 in den Transportspalt zweier Einzugswalzen 6, 7 vorbewegt, die an dem Ständer 1 drehbar gelagert sind und für den Weitertransport des Folienzuschnitts synchron angetrieben werden.In order to make it easy to pull off the remainder of the film from the carrier paper of each film blank 3, its leading edge 3 'is first cut by means of a
Hinter den beiden Einzugswalzen 6, 7 ist mit der Spitze eines abgewinkelten Leitbleches 9 eine Umlenkkante 8 ausgebildet, an welcher der Folienrest der Deckfolie im Zusammenwirken mit einer Transfereinrichtung 10 von dem Trägerpapier abgezogen wird. Bei diesem "Entstrippen" verbleibt also die durch Einschnitte der Deckfolie ausgebildete Werbeschrift oder Werbegrafik auf dem Trägerpapier, das hinter der Umlenkkante 8 in der vorgegebenen Transportrichtung 4 entfernt wird.Behind the two feed rollers 6, 7, a
Die Transfereinrichtung 10 ist mit einem gummielastischen Polster 11 ausgebildet, das an einem Transferschlitten 12 angeordnet ist. Der Transferschlitten 12 ist längs einer Führungsschiene 13 beweglich, die somit eine von der vorgegebenen Transportrichtung 4 an der Umlenkkante 8 abgezweigte Transferrichtung festlegt, in welcher der Folienrest von dem Trägerpapier jedes Folienzuschnittes 3 abgezogen wird. Dieses Abziehen des Folienrestes von dem Trägerpapier wird damit erhalten, daß das gummielastische Polster 11 anfänglich in eine solche Relativlage zu der Umlenkkante 8 eingestellt wird, daß bei der Ankunft eines Folienzuschnitts zuerst dessen Deckfolie mit dem Polster 11 in Berührung kommt. Dabei wird als Folge der mit der Schneideinrichtung 5 erzeugten Abschrägung der vorlaufenden Kante 3' eine Linienberührung der Deckfolie mit dem Polster 11 begünstigt, sodaß bei einer anschließend beginnenden Bewegung des Transferschlittens 12 in der abgezweigten Transferrichtung 14 der sich an die Abschrägung unmittelbar anschließende Randbereich der Deckfolie über die rückseitige Haftkleberschicht ein Anhaften an dem Polster 11 erfährt. Im Zusammenwirken mit der Umlenkkante 8 und weiter auch im Zusammenwirken mit dem Leitblech 9 wird danach ein Festkleben des vorlaufenden Randbereichs der Deckfolie an dem Polster 11 begünstigt, sodaß bei der weiteren Bewegung des Transferschlittens 12 in der Transferrichtung 14 der mit diesem vorlaufenden Randbereich zusammenhängende Folienrest 15 des Folienzuschnitts 3 dann sicher von dem Trägerpapier abgezogen werden kann, während das Trägerpapier mit der darauf verbleibenden Werbeschrift oder Werbegrafik in der vorgegebenen Transportrichtung 4 entfernt wird.The
Obwohl durch das Zusammenwirken der Umlenkkante 8 mit der Tranfereinrichtung 10 ein problemloses Abziehen des Folienrestes 15 ohne eine Beschädigungsgefahr für die auf dem Trägerpapier jedes Folienzuschnitts verbleibende Werbeschrift oder Werbegrafik gesichert ist, ist zweckmäßig in der Nähe der Umlenkkante 8 noch eine Bürste 8' angeordnet, mit welcher auf die Deckfolie jedes Folienzuschnitts derart eingewirkt wird, daß das Abtrennen des Folienrestes von der Werbeschrift oder Werbegrafik während des Abziehens des Folienrestes begünstigt wird. Weiterhin ist in der Nähe der Schneideinrichtung 5 zweckmäßig ein Wärmekanal 5' angeordnet, um noch vor dem Abziehen des Folienrestes eine Schrumpfung der Deckfolie und damit eine Vergrößerung der Schnittbreite der die Werbeschrift oder Werbegrafik ausbildenden Einschnitte zu erzielen. Auch mit dieser Maßnahme wird somit das an der Umlenkkante 8 beginnende Abziehen des Folienrestes von dem Trägerpapier begünstigt, wobei eine vergrößerte Schnittbreite der die Werbeschrift oder Werbegrafik ausbildenden Einschnitte daneben natürlich auch durch Verwendung von Konturenmessern mit entsprechend geformten Schnittkanten erzielbar ist, deren Verwendung jedoch für die Ausbildung von komplizierteren Konturen einer Werbeschrift oder Werbegrafik nicht immer möglich ist.Although the interaction of the
Die Transfereinrichtung 10 ist längs der Führungsschiene 13 bis hin zu einer Endposition bewegbar, in welcher der mit seinem vorlaufenden Randbereich an dem Polster 11 festgeklebte Folienrest 15 an eine Resterolle 16 übergeben wird. Die Übergabe wird damit erhalten, daß der Transferschlitten 12, der für diese Endposition mit einer Relativlage 12' dargestellt ist, um eine zu der Drehachse der Resterolle 16 parallele Achse verschwenkt wird. Weil bei diesem Verschwenken des Transferschlittens 12 auch das Polster 11' in eine veränderte Relativlage zu der Resterolle 16 gebracht wird, kann damit der Folienrest 15 mit seiner rückseitigen Haftkleberschicht gegen die Resterolle 16 angelegt werden. Wenn somit die Resterolle 16 im Anschluß an die in der Endposition des Transferschlittens bewirkte Anlage zunächst nur des vorlaufenden Randbereichs des Folienrestes 15 gedreht wird, dann wird dadurch der Folienrest 15 kontinuierlich auf die Resterolle 16 aufgenommen und über seine rückseitige Haftkleberschicht an der Resterolle festgeklebt. Um dieses Festkleben zu unterstützen, ist die Führungsschiene 13 zweckmäßig um eine nahe der Umlenkkante 8 vorgesehene Achse 17 verschwenkbar. Diese Verschwenkbarkeit der Führungsschiene 13 kann andererseits auch für das sichere Zusammenwirken des Transferschlittens 12 und seines Polsters 11 mit der Umlenkkante 8 zum Zeitpunkt der Übernahme des Folienrestes 15 an der Verzweigung der Transportrichtung 4 der Folienzuschnitte 3 genutzt werden.The
Die Resterolle 16 ist mit ihrer Drehachse 18 an einem Einzellenker 19 einer Lenkeranordnung gelagert, die noch einen zweiten Einzellenker 20 für die drehbare Lagerung einer an der Hüllfläche der Resterolle 16 anliegenden Antriebsrolle 21 aufweist. Die mit den beiden Einzellenkern 19, 20 ausgebildete Lenkeranordnung ist über eine Drehachse 22 des Einzellenkers 20 an dem Ständer 1 derart gelagert, daß sich die Drehachse 18 der Resterolle 16 mittels eines Gleitsteines 23 längs einer zu der Führungsschiene 13 der Transfereinrichtung 10 winkelmäßig ausgerichteten Schlitzführung 24 verschieben läßt. Diese Verschiebemöglichkeit der Drehachse 18 ergibt die Beibehaltung einer konstanten Antriebsübersetzung für die Antriebsrolle 21 in Bezug auf die Transportgeschwindigkeit der Folienzuschnitte 3 unter Berücksichtigung eines wachsenden Durchmessers der Resterolle 16 während der Füllung mit den Folienresten. Der Führungsschlitz 24 ist im übrigen mit einem offenen Ende ausgebildet, damit die Resterolle 16 nach dem Erreichen eines vorbestimmten Füllungsgrades und damit auch eines vorbestimmten maximalen Durchmessers entfernt und durch eine leere neue Resterolle ersetzt werden kann.The
Die verschiedenen, in der Zeichnung nicht näher dargestellten Antriebe für eine mit der Zuführung der Folienschnitte 3 synchronisierte Betätigung der Schneideinrichtung 5, für die Drehung der Einzugswalzen 6, 7, für die hin- und hergehende Bewegung des Transferschlittens 12, für die gegebenenfalls vorgesehene Schwenkbewegung der Führungsschiene 13 und für die Antriebsrolle 21 zur Drehung der Resterolle 16 können in Verbindung mit einer geeigneten Steuerung jede beliebige Ausbildung erhalten. Weiterhin kann die Vorrichtung noch ergänzt werden mit einer geeigneten Sammeleinrichtung für die Trägerpapiere der Folienzuschnitte 3, die hinter der mit der Umlenkkante 8 ausgebildeten Verzweigung mit der darauf jeweils verbleibenden Werbeschrift oder Werbegrafik in der vorgegebenen Transportrichtung 4 entfernt werden. Die Sammeleinrichtung kann dabei letztlich noch mit einer Appliziervorrichtung kombiniert sein, mit der die Werbeschriften oder Werbegrafiken von den Trägerpapieren auf einzelne Transferfolien übernommen werden, die als Hilfsmittel für das selbstklebende Anbringen der Werbeschriften oder Werbegrafiken an einer Werbefläche eingesetzt werden.The various drives, not shown in the drawing, for an operation of the
