Suitable for receiving and dispensing this arrangement of abrasive discs is a dispenser (40) which, in the area of its opening (41) from which the abrasive disc is taken, has an edge (42) via which the abrasive disc (20) to be taken out in each case can be pulled out together with its covering (23) while directing the same away from the abrasive disc (20). <IMAGE>

Description

Die Erfindung betrifft eine Anordnung von Schleifblättern auf Unterlagen, die auf der einen Seite das Schleifmittel tragen und auf der anderen Seite mit einer Haftkleberschicht versehen sind, die durch eine abziehbare Abdeckung abgedeckt ist, in Form eines Bandes.The invention relates to an arrangement of sanding sheets on documents which carry the abrasive on one side and are provided on the other side with a layer of pressure-sensitive adhesive, which is covered by a removable cover, in the form of a tape.

Die Erfindung bezieht sich darüber hinaus auf einen Dispenser zur Aufnahme und Abgabe einer derartigen Anordnung von Schleifblättern.The invention also relates to a dispenser for receiving and dispensing such an arrangement of sanding sheets.

Durch die US-PSen 3 267 623 und 3 849 949 sind Schleifscheiben bekannt, die dadurch bandartig verbunden sind, daß die Unterlage als durchgehendes Band ausgebildet ist. Bei einer ersten gemeinsamen Ausführungsform dieses Stands der Technik ist der jeweilige Abschnitt der Unterlage zwischen zwei benachbarten Schleifscheiben als schmaler Steg ausgebildet, der bei einer Abwandlung (US-PS 3 849 949) zum leichteren Durchtrennen des Steges perforiert ist. Bei einer anderen Ausführungsform (US-PS 3 267 623) sind die Schleifblätter über beinahe 360° aus der Unterlage herausgestanzt und über stehenbleibende, schmale Zungen mit der bandartigen Unterlage verbunden. Beiden Ausführungsformen ist der Nachteil gemeinsam, daß beim Abreißen einzelner Schleifscheiben am Scheibenrand ein Abschnitt des Steges oder der Zunge verbleibt, der gegenüber dem Scheibenrand hervorsteht. Dieser Vorstand kann sich nicht nur negativ auf das Schleifbild auswirken. Es besteht vielmehr auch noch die Gefahr, daß die Schleifscheiben im Bereich des bzw. der Vorstände einreißen, da diese über die geräteseitige Schleifblattaufnahme hervorstehen und deshalb beim Arbeiten mit dem Schleifgerät sehr leicht an Unebenheiten des Werkstücks oder dergleichen hängenbleiben.Grinding wheels are known from US Pat. Nos. 3,267,623 and 3,849,949, which are connected in a band-like manner in that the base is designed as a continuous band. In a first common embodiment of this prior art, the respective section of the support between two adjacent grinding wheels is designed as a narrow web which, in a modification (US Pat. No. 3,849,949), is perforated for easier severing of the web. In another embodiment (US Pat. No. 3,267,623), the sanding sheets are punched out of the base over almost 360 ° and connected to the band-like base by means of narrow tongues which remain. Both embodiments have the disadvantage in common that when individual grinding wheels are torn off at the wheel edge, a section of the web or tongue remains which protrudes from the wheel edge. This board cannot only have a negative impact on the grinding pattern. Rather, it still exists the risk that the grinding wheels tear in the area of the board or members of the board, since these protrude from the device-side grinding sheet holder and therefore very easily get caught on unevenness of the workpiece or the like when working with the grinding device.

Beim Stand der Technik werden die Schleifscheibenbänder zu Rollen aufgewickelt, die vorzugsweise in entsprechend ausgebildeten Dispensern eingebracht werden. - Aufgrund dieser Anordnung sind die von der Rolle abgezogenen Schleifscheiben gewölbt. Diese Wölbung erschwert erheblich ein exaktes Aufbringen der Schleifscheiben auf die geräteseitige Schleifblattaufnahme. Es besteht nämlich die Gefahr, daß die Scheibe nicht völlig plan auf der geräteseitigen Schleifblattaufnahme aufliegt und u.U. sogar Falten bildet. Die den Schleifscheiben abgezwungene Wölbung erschwert auch das Ablösen der flexiblen, abziehbaren Abdeckung von der Haftkleberschicht.In the prior art, the grinding wheel belts are wound into rolls, which are preferably introduced into appropriately designed dispensers. - Due to this arrangement, the grinding wheels pulled off the roll are curved. This curvature considerably complicates the exact application of the grinding wheels to the device-side grinding wheel holder. This is because there is a risk that the wheel may not lie completely flat on the device-side sanding sheet holder and may even wrinkles. The curvature forced out of the grinding wheels also makes it difficult to detach the flexible, removable cover from the pressure-sensitive adhesive layer.

Bei der Schleifscheibenanordnung nach der US-PS 3 849 949 ist zudem die Haftkleberschicht nicht mittels einer abziehbaren Abdeckung geschützt. Dies verbilligt zwar die Herstellung, jedoch kann die Klebekraft der Haftkleberschicht durch Staubeinwir- kung, die dann nicht ausgeschlossen ist, wenn die Verpackung bzw. der Dispenser bereits geöffnet ist, so stark vermindert werden, daß die Haftung zwischen der Schleifscheibe und der geräteseitigen Schleifblattaufnahme so gering ist, daß sich die jeweilige Schleifscheibe schnell von der geräteseitigen Schleifblattaufnahme löst.In the grinding wheel arrangement according to US Pat. No. 3,849,949, the pressure-sensitive adhesive layer is also not protected by means of a removable cover. While this reduces the cost of manufacture, however, the adhesive force of the pressure-sensitive adhesive layer can be Staubeinwir- kun g, which is not excluded if the packaging or the dispenser is already open, are so greatly reduced that the adhesion between the grinding wheel and the apparatus-side abrasive sheet receiving is so small that the respective grinding wheel quickly detaches from the device-side grinding wheel holder.

Die bekannten Schleifscheibenanordnungen können aufgrund der kompliziert gestalteten Unterlagen nur mit Spezialstanzen hergestellt werden, die an Stanzwerkzeuge der herauszustanzenden Form der Unterlage angepaßt ist.The known grinding wheel assemblies can only be produced with special punches due to the complicated design of the underlay, which is adapted to punching tools of the shape of the underlay to be punched out.

Demgegenüber ist es Aufgabe der Erfindung, eine Anordnung von Schleifbändern der vorausgesetzten Art zu schaffen, bei der die abgenommenen Schleifblätter einen rundum glatten Rand besitzen, die Schleifblätter -zur Verfügung stellt, die exakt auf die geräteseitige Schleifblattaufnahme aufbringbar sind und die darüber hinaus billig in der Herstellung ist.In contrast, it is an object of the invention to provide an arrangement of sanding belts of the presupposed type, in which the removed sanding sheets have an all-round smooth edge, the sanding sheets - are available, which can be applied exactly to the device-side sanding sheet receptacle and which are also inexpensive to use Manufacturing is.

Diese Aufgabe wird bei einer Anordnung von Schleifbändern der vorausgesetzten Art dadurch gelöst, daß die Schleifblätter durch mit den Abdeckungen verbundenen Verbindungsstreifen zu einem Band zusammengefaßt sind, und die benachbarten Schleifblätter unter Falten des jeweiligen zwischen zwei benachbarten Schleifblättern liegenden freien Abschnitts des Verbindungsstreifens flach übereinander zu liegen kommen.This object is achieved with an arrangement of abrasive belts of the presupposed type in that the abrasive sheets are combined to form a band by connecting strips connected to the covers, and the adjacent abrasive sheets lie flat on top of one another with folds of the free section of the connecting strip lying between two adjacent abrasive sheets come.

Bei der erfindungsgemäßen Lösung werden also die Schleifblätter getrennt hergestellt und erst dann durch das vorgeschlagene Aufbringen der Verbindungsstreifen zu einem Band zusammengefaßt. Die derart zu einem Band verbundenen Schleifblätter werden schließlich unter Falten des jeweiligen zwischen zwei benachbarten Schleifblättern liegenden freien Abschnittes des Verbindungsstreifens flach übereinander gestapelt. In dieser Anordnung werden die Schleifblätter verpackt und gelagert.In the solution according to the invention, the sanding sheets are thus produced separately and only then combined into a band by the proposed application of the connecting strips. The sanding sheets connected in this way to form a band are finally stacked flat on top of one another, folding the respective free section of the connecting strip lying between two adjacent sanding sheets. The sanding sheets are packaged and stored in this arrangement.

Die erfindungsgemäße Lösung erbringt den Vorteil, daß die von den Verbindungsstreifen abgenommenen Schleifblätter einen vollkommen glatten Rand haben, weil keine Überstände vorhanden sind, wie dies bei den bekannten Schleifscheiben der Fall ist. Ein weiterer Vorteil der erfindungsgemäßen Anordnung besteht darin, daß die Schleifblätter stets flach liegen. Dadurch können die Schleifblätter einfach und exakt auf die geräteseitige Schleifblattaufnahme aufgebracht werden. Die stets flachen Schleifblätter erleichtern auch ein Abziehen der flexiblen Abdeckung von der Haftkleberschicht. Schließlich ist die erfindungsgemäße Schleifblattanordnung einfach und billig herstellbar. Die Schleifblätter werden einzeln mit einfachen Vorrichtungen hergestellt. Mit einer ebenso einfachen zusätzlichen Vorrichtung werden lediglich anschließend die Verbindungsstreifen mit den Abdeckungen der linear angeordneten Schleifblätter verbunden, um diese zu einem Band zusammenzufassen.The solution according to the invention has the advantage that the sanding sheets removed from the connecting strips have a completely smooth edge because there are no protrusions, as is the case with the known grinding wheels. Another advantage of the arrangement according to the invention is that the sanding sheets are always flat. This means that the sanding sheets can be easily and precisely applied to the sanding sheet holder on the device. The always flat sanding sheets also make it easier to remove the flexible cover from the adhesive layer. Finally, the sanding sheet arrangement according to the invention is simple and inexpensive to manufacture. The sanding sheets are manufactured individually with simple devices. With an equally simple additional device, the connecting strips are then only connected to the covers of the linearly arranged sanding sheets in order to combine them into a band.

Der erfindungsgemäß vorgesehene Verbindungsstreifen kann aus Papier, Folie oder aus einem textilen Material bestehen. Das Material muß nur ausreichend flexibel sein, so daß es ohne Gefahr eines Reißens bzw. bleibenden Knickens verformt und gefaltet werden kann. Zum Zweck der Materialersparnis ist der Verbindungsstreifen erheblich schmaler als die Breite der verbindenden Schleifblätter. Zur weiteren Materialersparnis ist es vorteilhaft, daß ein Verbindungsstreifen nur jeweils zwei benachbarte Schleifbänder miteinander verbindet. Es kann aber auch zweckmäßig sein, wenn für das gesamte Band ein durchgehender Verbindungsstreifen verwendet wird. Die Abdeckung der Haftkleberschicht der Schleifblätter kann wie üblich ausgebildet sein. Die von der Haftkleberschicht abgewandte Seite der Abdeckung muß nur so beschaffen sein, daß der Verbindungsstreifen mit üblichen Klebern gut mit der Abdeckung verklebt werden kann.The connecting strip provided according to the invention can consist of paper, film or a textile material. The material only has to be sufficiently flexible so that it can be deformed and folded without the risk of tearing or permanent kinking. For the purpose of saving material, the connecting strip is considerably narrower than the width of the connecting sanding sheets. To further save material, it is advantageous that a connecting strip connects only two adjacent abrasive belts to one another. However, it can also be expedient if a continuous connecting strip is used for the entire band. The cover of the pressure-sensitive adhesive layer of the sanding sheets can be designed as usual. The side of the cover facing away from the pressure-sensitive adhesive layer only has to be such that the connecting strip can be well glued to the cover using conventional adhesives.

Da bei der erfindungsgemäßen Anordnung die Schleifblätter stets flach liegen, kann diese auch für Schleifmittel von grober Körnung eingesetzt werden, was bei den bekannten Anordnungen aufgrund des Aufrollens der Schleifblätter auf Rollen nicht möglich ist.Since the sanding sheets are always flat in the arrangement according to the invention, this can also be used for abrasives of coarse grain, which is not possible in the known arrangements due to the rolling up of the sanding sheets on rollers.

Bei der erfindungsgemäßen Anordnung können die Schleifblätter in zweierlei Weise übereinandergestapelt werden. Bei einer Ausführungsform kommt jedes Schleifblatt mit seiner Abdeckung auf der Schleifmittelseite des im Band benachbarten, darunterliegenden Schleifblatts zu liegen. Dies ergibt eine besonders einfache Entnahmemöglichkeit des jeweiligen Schleifblatts, weil die Schleifmittelseite jedes Schleifblatts oben liegt. Bei dieser Anordnung kann die Länge des freien, d.h. nicht mit den Abdeckungen verbundenen Abschnitts des zwischen zwei benachbarten Schleifblättern liegenden Verbindungsstreifens der Länge eines Schleifblatts entsprechen. In diesem Fall kommt dieser Abschnitt zwischen den benachbarten Schleifbändern zu liegen. Bei der anderen Möglichkeit liegt jedes Schleifblatt mit seiner Schleifmittelseite gegen die Schleifmittelseite des einen benachbarten Schleifblatts und mit der Abdeckung gegen die Abdeckung des anderen benachbarten Schleifblatts an und die Länge des freien, zwischen zwei benachbarten Schleifblättern liegenden freien Abschnitts des Verbindungsstreifens entspricht der zweifachen Dicke des Schleifblatts. Dadurch ist eine ziehharmonikaartige Anordnung der Schleifblätter gegeben, die den Vorteil besitzt, daß in dem Fall, in dem ein Verbindungsstreifen nur jeweils zwei benachbarte Schleifblätter miteinander verbindet, dieser Verbindungsstreifen kürzer ist als bei der ersten Anordnungsform.In the arrangement according to the invention, the sanding sheets can be stacked on top of one another in two ways. In one embodiment, each abrasive sheet comes to rest with its cover on the abrasive side of the adjacent abrasive sheet in the belt. This results in a particularly simple way of removing the respective sanding sheet because the abrasive side of each sanding sheet is on top. With this arrangement, the length of the free, ie not connected to the covers, section of the connecting strip lying between two adjacent sanding sheets can correspond to the length of one sanding sheet. In this case, this section comes to lie between the adjacent grinding belts. In the other possibility, each abrasive sheet lies with its abrasive side against the abrasive side of one adjacent abrasive sheet and with the cover against the cover of the other adjacent abrasive sheet and the length of the free, lying between two adjacent abrasive sheets free section of the connecting strip corresponds to twice the thickness of the sanding sheet. This results in an accordion-like arrangement of the sanding sheets, which has the advantage that in the case in which a connecting strip connects only two adjacent sanding sheets to one another, this connecting strip is shorter than in the first arrangement form.

Die erfindungsgemäße Anordnung eignet sich nicht nur für runde Schleifblätter, sondern auch für Schleifblätter jeder beliebigen anderen Form.The arrangement according to the invention is suitable not only for round sanding sheets, but also for sanding sheets of any other shape.

Für die Aufnahme und Abgabe der erfindungsgemäßen Anordnung von Schleifblättern eignet sich besonders vorteilhaft ein Dispenser, der im Bereich seiner Entnahmeöffnungen eine Kante aufweist, über die das jeweils zu entnehmende Schleifblatt mit seiner Abdeckung unter Weglenken derselben vom Schleifblatt ziehbar ist. Auf diese Weise wird beim einfachen Herausziehen des jeweiligen Schleifblatts, indem dieses am freien Ende des Verbindungsstreifens erfaßt wird, die Abdeckung von der Haftkleberschicht dieses Schleifblatts gelöst.A dispenser which has an edge in the region of its removal openings, over which the sanding sheet to be removed in each case with its cover can be pulled away from the sanding sheet while deflecting it, is particularly advantageously suitable for receiving and dispensing the arrangement of sanding sheets according to the invention. In this way, when the respective sanding sheet is simply pulled out by grasping it at the free end of the connecting strip, the cover is detached from the pressure-sensitive adhesive layer of this sanding sheet.

Der Dispenser stellt vorteilhafterweise zugleich die Verpackung dar. In diesem Fall besteht er vorzugsweise aus Karton. Die Abziehkante ist zweckmäßigerweise verstärkt, z.B. mittels einer zweiten Kartonlage oder mittels einer Aluminiumleiste,die aufgeklebt oder aufgenietet ist.The dispenser advantageously also represents the packaging. In this case, it preferably consists of cardboard. The pull-off edge is expediently reinforced, e.g. by means of a second layer of cardboard or by means of an aluminum strip that is glued or riveted on.

Es kann aber auch ein separater Dispenser zur Verfügung gestellt werden, der z.B. aus Metall besteht und für die Aufnahme mehrerer Schleifblattbänder, z.B. mit unterschiedlich großen Schleifblättern oder Schleifmitteln unterschiedlicher Körnung, ausgelegt ist.However, it is also possible to provide a separate dispenser which, for example, consists of metal and is designed to hold several sanding sheet belts, e.g. with sanding sheets of different sizes or abrasives of different grain sizes.

Die als kreisrunde Schleifscheiben ausgebildeten und insgesamt mit 10 bzw. 20 bezeichneten Schleifblätter bestehen jeweils aus einer Unterlage 11 bzw. 21, auf deren einen Seite das Schleifmittel 12 bzw. 22 aufgebracht ist und deren andere Seite mit einer Haftkleberschicht versehen ist, die mittels einer Abdekkung 13 bzw. 23 geschützt ist. Die einzelnen Schleifscheiben 10 bzw. 20 sind durch mit den Abdeckungen 13 bzw. 23 verbundenen Verbindungsstreifen 14 bzw. 24 zu einem Band zusammengefaßt.The grinding sheets, which are designed as circular grinding disks and are designated overall by 10 or 20, each consist of a base 11 or 21, on one side of which the abrasive 12 or 22 is applied and the other side of which is provided with a layer of pressure-sensitive adhesive which is covered by a cover 13 or 23 is protected. The individual grinding wheels 10 and 20 are combined to form a band by connecting strips 14 and 24 connected to the covers 13 and 23, respectively.

Aus den Fig. 1 und 2 ist eine erste mögliche Anordnung der Schleifscheiben 10 'ersichtlich. Nach dieser Anordnung kommt jede Schleifscheibe 10 mit der Abdeckung 13 auf der Schleifmittelseite 12 der im Band benachbarten, darunterliegenden Schleifscheibe 10 flach zu liegen. Hierfür ist die Länge des freien Abschnitts des zwischen zwei benachbarten Schleifscheiben 10 liegenden Verbindungsstreifens 14 in etwa dem Durchmesser einer Schleifscheibe 10..angepaßt. Dieser freie Abschnitt des jeweiligen Verbindungsstreifens 14 kommt zwischen den benachbarten Schleifscheiben 10 zu liegen. Aufgrund dieser Anordnung können die Schleifscheiben 10, wie in Fig. 1 angedeutet, durch Ziehen an dem freien Ende des Verbindungsstreifens 14 der jeweils obersten Schleifscheibe 10 durch Entfalten der Verbindungsstreifen 14 von dem Stapel abgezogen werden.1 and 2 show a first possible arrangement of the grinding wheels 10 '. According to this arrangement, each grinding wheel 10 comes to lie flat with the cover 13 on the abrasive side 12 of the grinding wheel 10 adjacent in the band and lying underneath. For this purpose, the length of the free section of the connecting strip 14 lying between two adjacent grinding wheels 10 is adapted approximately to the diameter of a grinding wheel 10. This free section of the respective connecting strip 14 comes to lie between the adjacent grinding wheels 10. Due to this arrangement, as indicated in FIG. 1, the grinding wheels 10 can be pulled off the stack by pulling on the free end of the connecting strip 14 of the uppermost grinding wheel 10 by unfolding the connecting strips 14.

Bei der Anordnung nach Fig. 3 liegt jede Schleifscheibe 20 mit ihrer Schleifmittelseite 22 flach gegen die Schleifmittelseite 22 der einen benachbarten Schleifscheibe 20 und mit der Abdeckung 23 gegen die Abdeckung 23 der anderen benachbarten Schleifscheibe 20 an. Bei dieser Anordnung entspricht die Länge des freien, zwischen zwei benachbarten Schleifscheiben 20 liegenden Abschnitts des Verbindungsstreifens 24 in etwa der zweifachen Dicke einer Schleifscheibe 20.3, each grinding wheel 20 lies flat with its abrasive side 22 against the abrasive side 22 of one adjacent grinding wheel 20 and with the cover 23 against the cover 23 of the other adjacent grinding wheel 20. In this arrangement, the length of the free section of the connecting strip 24 lying between two adjacent grinding wheels 20 corresponds approximately to twice the thickness of a grinding wheel 20.

Beiden Ausführungsformen ist gemeinsam, daß ein Ver- bindungsstreifen 14 bzw. 24 nur jeweils zwei benachbarte Schleifscheiben 10 bzw. 20 miteinander verbindet.Both embodiments have in common that a comparison Bonds g sstreifen 14 and 24, only two adjacent grinding wheels 10 and 20 to each other.

Aus Fig. 4 ist ein Dispenser ersichtlich, aus dem die einzelnen Schleifscheiben 20, die z.B. nach Fig. 3 angeordnet sind, entnommen werden können. Dieser Dispenser ist insgesamt mit 40 bezeichnet. Er besteht aus einem Gehäuse, z.B. aus Metall, das an seiner Oberseite eine Entnahmeöffnung 41 aufweist. An einer Längsseite des Dispensers 40 ist eine Platte 43 angeordnet, die sich schräg nach oben erstreckt und in einer Kante 42 endet, die oberhalb der Entnahmeöffnung 41 des Dispensers 40 liegt. Die Platte -43 setzt sich von der Kante 42 fort in Gestalt einer nach oben offenen Rinne 44, in der zwei Schlitze 45 ausgebildet sind.4 shows a dispenser from which the individual grinding wheels 20, e.g. 3 are arranged, can be removed. This dispenser is labeled 40 in total. It consists of a housing, e.g. made of metal, which has a removal opening 41 on its upper side. A plate 43 is arranged on a long side of the dispenser 40, which extends obliquely upwards and ends in an edge 42 which lies above the removal opening 41 of the dispenser 40. The plate -43 continues from the edge 42 in the form of an upwardly open channel 44 in which two slots 45 are formed.

Die Funktionsweise des beschriebenen Dispensers ist die folgende: In das zur Aufnahme von zwei Kartons mit je einem Schleifblattstapel ausgelegte Gehäuse des Dispensers ist ein Karton 50 eingesetzt, in dem ein Stapel von Schleifscheiben 20 gelagert ist. Der Deckel des Kartons 50 ist nach oben geklappt und durch eine Lasche an der Platte 43 in dieser Lage gehalten. Zur Entnahme der Schleifscheiben 20 aus dem Dispenser 40 wird die oberste Schleifscheibe 20 in den Bereich der Kante 42 geführt. Die Abdeckung 23 wird z.B. durch Ziehen an dem vorderen Verbindungs-streifen 24 ein Stück im vorderen Bereich der Schleifscheibe 20 abgezogen und in den zugeordneten Schlitz 45 eingeführt. Wird in dieser Stellung an dem vorderen Verbindungsstreifen 24 bzw. an dem abgelösten Teil der Abdeckung 23 gezogen, löst sich die Abdeckung 23 durch Herausziehen aus dem Schlitz 45 vollständig von der betrachteten Schleifscheibe 20 ab, so daß diese Schleifscheibe 20 dem Band entnommen werden kann. Das Abziehen der jeweiligen Abdeckung 23 von den nachfolgenden Schleifscheiben 20 erfolgt einfach durch weiteres Ziehen an den Verbindungsstreifen bzw. den Abdeckungen.The way in which the dispenser described works is as follows: A box 50 in which a stack of grinding wheels 20 is mounted is inserted into the dispenser housing, which is designed to hold two boxes, each with a stack of sanding sheets. The lid of the carton 50 is folded up and held in this position by a tab on the plate 43. To remove the grinding wheels 20 from the dispenser 40, the top grinding wheel 20 is guided into the area of the edge 42. The cover 23 is, for example, by pulling on the front strip-Verbindun s g a piece 24 in the front region of the grinding wheel 20 removed and inserted into the associated slot 45th If the front connecting strip 24 or the detached part of the cover 23 is pulled in this position, the cover 23 is completely detached from the grinding wheel 20 under consideration by pulling it out of the slot 45, so that this grinding wheel 20 can be removed from the belt. The respective cover 23 is removed from the subsequent grinding wheels 20 simply by further pulling on the connecting strips or the covers.
