Description

Die Erfindung betrifft ein Verfahren zur Herstellung einer Schleif- und/oder Polierdiskette, sowie eine Schleif- und/oder Polierdiskette.The invention relates to a method for producing a grinding and / or polishing disk, and a grinding and / or polishing disk.

Aus der AT B 389 839 ist ein Verfahren zur Herstellung einer Schleif- oder Polierscheibe bekannt, bei dem ein rechteckiges Blatt über seine gesamte Länge von beiderseits der sowie im Abstand von der Mittellinie liegenden Stellen bis zu den zugeordneten, einander gegenüberliegenden Rändern unter Bildung streifenförmiger Lamellen durchschnitten wird, danach um die Mittellinie umgebogen und mit einem entlang der Mittellinie eingelegten drahtförmigen Halteelement versehen wird, worauf das Blatt mit innenliegender Mittellinie zu einem Ring geschlossen wird, und welches Verfahren dadurch gekennzeichnet ist, dass als Halteelement ein Draht aus schmelzbarem Material verwendet wird, dass das vorzugsweise aus Sand-, Glas- oder Schmiergelpapier bestehende Blatt nach Einlegen des Halteelementes sowie mit freiliegendem Bugrücken gefalzt wird und dass das Halteelement nach dem Falzen sowie nach dem Schließen des Blattes zum Ring erhitzt wird.From AT B 389 839 is a method for producing a grinding or polishing wheel known in which a rectangular sheet over its entire length from both sides of the at intervals from the midline points to the associated one another opposite edges is cut to form strip-shaped fins, then bent around the midline and inserted with a along the midline wire-shaped holding element is provided, whereupon the sheet with internal center line is closed to a ring, and which method is characterized in that As a holding element, a wire of fusible material is used, that the preferably consisting of sand, glass or lubricating paper sheet after inserting the Holding element as well as with exposed Bugrücken is folded and that the holding element is heated after folding and after closing the sheet to the ring.

Hierbei dient der Draht aus schmelzbarem Material einerseits zur Verbindung der Innenseiten des gefalzten Blattes im Bereich der Mittellinie, andererseits als Verstärkungseinlage und weiters zur Befestigung einer einzelnen Scheibe im Werkzeug. Es hat sich jedoch gezeigt, dass der Draht aus schmelzbarem Material eine örtliche Verdickung direkt am Falz bildet, wodurch entweder Einspannkräfte am Werkzeug direkt nur auf den Falz wirken, was bedeutet, dass die Lamellen lediglich mit ihren nur eine äußerst geringe radiale Erstreckung aufweisenden Falzenden am Werkzeug festgehalten sind, oder ein Raum für die Verdickung am Einspannwerkzeug vorgesehen werden muss. Weiters ist eine solche Diskette infolge der Beweglichkeit des Drahtes aus schmelzbarem Material sehr fragil und leicht deformierbar.Here, the wire is made of meltable material on the one hand to connect the Inner sides of the folded sheet in the region of the center line, on the other hand as Reinforcement insert and further for fixing a single disc in the tool. It However, it has been shown that the wire of fusible material, a local thickening forms directly on the fold, whereby either clamping forces on the tool directly on the Fold acting, which means that the slats only with their only a very small radially extending hemming are held on the tool, or a space must be provided for the thickening of the clamping tool. Furthermore, such is one Floppy disc due to the mobility of the wire of fusible material very fragile and easily deformable.

Aus der WO 91/17867 ist es bekannt zur Herstellung einer Schleif- und/oder Polierdiskette ein rechteckiges Schleif- oder Polierblatt über seine gesamte Länge unter Bildung streifenförmiger Lamellen einzuschneiden, und zwar von einem Rand aus, wodurch es zur Bildung der Lamellen kommt. Anschließend wird das Blatt auf eine Ringscheibe aufgeklebt, wobei die freien Enden der Lamellen radial nach Außen gerichtet zu Liegen kommen. Zum Aufkleben des Blattes auf die Ringscheibe wird ein passender Kleber eingesetzt, wie z.B. ein doppelseitiges Klebeband. Das Aufbringen eines doppelseitigen Klebebandes auf eine Kreisringscheibe gestaltet sich jedoch nicht einfach, da es zu Faltenbildung kommt. Will man eine solche Faltenbildung vermeiden, müsste man ein sehr schmales Klebeband verwenden, was wiederum nur geringe Haltekräfte für das Schleif- bzw. Polierblatt ergibt.From WO 91/17867 it is known for the production of a grinding and / or polishing disk a rectangular abrasive or polishing blade over its entire length to form strip-shaped lamellae, from one edge, making it to the Formation of the slats comes. Subsequently, the sheet is glued to an annular disc, wherein the free ends of the slats are directed radially outward to lie. To the Gluing the sheet to the ring disk, a suitable adhesive is used, e.g. one double-sided adhesive tape. The application of a double-sided adhesive tape to a Annular disk is not easy, since it comes to wrinkles. Want To avoid such wrinkling, you would have a very narrow tape use, which in turn results in only low holding forces for the grinding or polishing blade.

Aus der DE 299 20 641 U1 ist es bekannt, ein rechteckiges Schleifblatt unter Bildung streifenförmiger Lamellen von einem Rand her einzuschneiden und das Blatt zwischen zueinandergepressten Lamellenkränzen einzuspannen.From DE 299 20 641 U1 it is known to form a rectangular abrasive sheet incise strip-shaped lamellae from one edge and place the leaf between them clamped to each other pressed lamellae rings.

Die Erfindung bezweckt die Vermeidung dieser Nachteile und Schwierigkeiten und stellt sich die Aufgabe, ein Verfahren zum Herstellen einer formstabilen Schleif- und/oder Polierdiskette sowie eine Schleif- und/oder Polierdiskette zu schaffen, welche eine Einspannung der Lamellen über einen vorbestimmten planparallelen radialen Bereich des Werkzeuges ermöglichen, sodass die Lamellen äußerst stabil im Werkzeug einspannbar sind.The invention aims to avoid these disadvantages and difficulties and provides the task, a method for producing a dimensionally stable grinding and / or To create a polishing disk and a grinding and / or polishing disk, which a Clamping the lamellae over a predetermined plane-parallel radial region of the Tool allow so that the blades are extremely stable in the tool clamped.

Diese Aufgabe wird bei einem Verfahren zur Herstellung einer Schleif- und/oder Polierdiskette durch die Kombination folgender Verfahrensschritte gelöst:

  • dass ein rechteckiges Schleif- oder Polierblatt, insbesondere ein Blatt Schleif- oder Poliergewebe, auf der Rückseite an einem Längsrand mit einem Band beklebt wird und
  • über seine gesamte Länge unter Bildung streifenförmiger Lamellen eingeschnitten wird, und zwar von dem dem Band gegenüberliegenden Längsrand ausgehend bis in das Band reichend,
  • worauf das Blatt mit dem Band auf einen Tragring aufgeklebt wird, wobei die Lamellen strahlenförmig radial nach außen gerichtet werden.
This object is achieved in a method for producing a grinding and / or polishing disk by the combination of the following method steps:
  • that a rectangular grinding or polishing sheet, in particular a sheet of abrasive or polishing fabric, on the back of a longitudinal edge is covered with a tape and
  • is cut over its entire length to form strip-like lamellae, starting from the longitudinal edge opposite the strip, reaching into the strip,
  • whereupon the sheet is adhered to a support ring with the ribbon, the lamellae being directed radially outward.

Das Herstellverfahren lässt sich deutlich vereinfachen, wenn auf das Blatt ein doppelseitiges Klebeband aufgeklebt wird, und weiters noch dadurch, dass als Tragring das Blatt auf einen flachen Kunststoffring aufgeklebt wird.The manufacturing process can be significantly simplified if a double-sided Adhesive tape is glued, and further by the fact that as a supporting ring the sheet on a glued flat plastic ring.

Vorzugsweise wird das Blatt mit dem Band und dem Tragring einem Pressdruck zum Festigen der Klebestellen ausgesetzt.Preferably, the sheet with the band and the support ring is a pressing pressure for Fixing the splices exposed.

Um das Blatt mit den fertig geschnittenen Lamellen leicht in eine Kreisform biegen zu können, wird zweckmäßig beim Schneiden der Lamellen das Band bis über die Hälfte seiner Breite eingeschnitten, vorzugsweise bis etwa 4/5 der Breite des Bandes. In order to easily bend the sheet with the ready-cut laminations into a circular shape, is suitably cut the tape to about half its width during cutting of the lamellae, preferably to about 4/5 of the width of the tape.

Gemäß einer bevorzugten Ausführungsform wird der Tragring beidseitig mit einem Blatt Schleif- oder Poliergewebe beklebt.According to a preferred embodiment, the support ring is on both sides with a sheet Glued or polished fabric.

Eine Schleif- und/oder Polierdiskette mit sich strahlenförmig radial von einem Tragring nach außen erstreckenden Lamellen, gebildet von einem Schleif- oder Polierblatt, wobei die Lamellen an ihren radial inneren Enden zusammenhängen, die Lamellen an ihren radial nach innen gerichteten Enden mit Klebstoff an einem Band aufgeklebt sind und das Band mit Klebstoff auf dem Tragring aufgeklebt ist, ist erfindungsgemäß dadurch gekennzeichnet, dass das Band teilweise durchschnitten ist, jedoch an seinem radial innenseitigen Rand zusammenhängend ist.A grinding and / or polishing disk with radially radially from a support ring after outwardly extending fins formed by a grinding or polishing blade, wherein the Slats at their radially inner ends are related, the slats at their radially to inwardly directed ends are glued to a tape with adhesive and the tape with Adhesive is glued to the support ring, is characterized in accordance with the invention, that the band is partially cut, but at its radially inner edge is connected.

Zwecks einfacher Fertigung ist zweckmäßig der Tragring als flacher Kunststoffring ausgebildet.For ease of manufacture is useful the support ring as a flat plastic ring educated.

Vorzugsweise ist der Tragring beidseitig mit Lamellen beklebt.Preferably, the support ring is covered on both sides with slats.

Die Erfindung ist nachfolgend anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert, wobei Fig. 1 ein rechteckiges Blatt Schleifgewebe bzw. Poliergewebe, Fig. 2 das Aufbringen dieses Blattes auf einen Tragring und Fig. 3 einen Querschnitt durch eine Schleif- bzw.

Dieses Blatt 1 wird an der Rückseite 2 mit einem doppelseitigen Klebeband 3 beklebt, und zwar entlang eines Längsrandes 4, wobei das Klebeband 3 eine Breite 5 zwischen 1/10 bis 1/5 der Breite 6 des rechteckigen Blattes 1 aufweist. Das Klebeband 3 schließt genau mit dem Längsrand 4 des Blattes 1 ab.This sheet 1 is pasted on the back 2 with a double-sided tape 3, along a longitudinal edge 4, the adhesive tape 3 having a width between 5 1 / 10-1 / 5 of the width 6 of the rectangular sheet. 1 The adhesive tape 3 terminates exactly with the longitudinal edge 4 of the sheet 1.

Als nächster Verfahrensschritt wird das Blatt 1 mit Einschnitten 7 versehen, und zwar ausgehend von dem Längsrand 8 des Blattes 1, der dem mit dem Klebeband 3 versehenen Längsrand 4 gegenüberliegt, wobei sich die Einschnitte 7 in das Klebeband 3 hinein erstrecken, jedoch knapp vor dem mit dem Klebeband 3 versehenen Längsrand 4 des Blattes 1 enden. Vorzugsweise erstrecken sich die Einschnitte 7 bis über die Hälfte der Breite 5 des Klebebandes 3, insbesondere bis etwa 4/5 der Breite 5 des Klebebandes 3, d.h. dass 1/5 derAs the next method step, the sheet 1 is provided with incisions 7, starting from the longitudinal edge 8 of the sheet 1, which is opposite to the provided with the adhesive tape 3 longitudinal edge 4, wherein the incisions 7 extend into the adhesive tape 3, but just before with the adhesive tape 3 provided longitudinal edge 4 of the sheet 1 ends. Preferably, the notches 7 of the adhesive tape 3, which means that 1 to extend over half the width of the adhesive tape 5 3, in particular to about 4/5 of the width of 5/5 of the

Breite 5 des Klebebandes 3 nicht durchschnitten wird, sodass die durch die Einschnitte 7 gebildeten Lamellen 9 an diesem Rand 4 noch zusammenhängen. Die Einschnitte 7 sind über die gesamte Länge 10 des Blattes 1 vorgesehen, und zwar im Abstand 11 der Breite der Lamellen 9.Width 5 of the adhesive tape 3 is not cut, so that through the incisions. 7 formed lamellae 9 are still related to this edge 4. The incisions 7 are over the entire length 10 of the sheet 1 is provided, at a distance 11 of the width of the Slats 9.

Nachfolgend wird das Blatt 1, wie aus Fig. 2 zu ersehen ist, auf einen flachen Tragring 12 mit einer Breite 13, die etwa der Breite 5 des Klebebandes 3 entspricht, aufgeklebt, sodass sich im aufgeklebten Zustand die Lamellen 9 strahlenförmig radial nach außen erstrecken und der mit dem Klebeband 3 versehene Längsrand 4 des Blattes 1 auf dem Innenrand 14, der dieselbe Länge aufweist wie das Blatt 1, des Tragringes 12 zu liegen kommt.Subsequently, the sheet 1, as can be seen from Fig. 2, on a flat support ring 12th with a width 13 which corresponds approximately to the width 5 of the adhesive tape 3, glued, so in the affixed state, the fins 9 radially extend radially outward and provided with the adhesive tape 3 longitudinal edge 4 of the sheet 1 on the inner edge 14, the same length as the sheet 1, the support ring 12 comes to rest.
