KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Dünnschichtige Schleifscheiben, insbesondere von großem Durchmesser, wie sie bei Schleifmaschinen mit umlaufenden Stahlscheiben Verwendung finden, sind bei ihrer Verschickung erheblicher Bruchgefahr ausgesetzt, auch wenn ihre Verpackung sorgfältig durchgeführt ist, ganz abgesehen davon, daß eine solche Verpackung mit Rücksicht auf ihre Sperrigkeit im Vergleich zu den Kosten der Scheibe selbst erhebliche Ausgaben verursacht.Thin-layer grinding wheels, especially large-diameter ones, such as those found on grinding machines with rotating steel disks are used, are exposed to a considerable risk of breakage when they are shipped, even if their packaging is carefully done, not to mention that such packaging considering its bulkiness compared to the cost of the disc itself causes significant expenses.
Bei der den Gegenstand der Erfindung bildenden Schleifscheibe wird dieser Ubelstand dadurch vermieden, daß ihr Schleifbelag mehrteilig ausgeführt und auf einer die Teile zusammenhaltenden biegsamen Unterlage befestigt ist. Durch diese Teilung läßt sich die Scheibe in eine leicht versendbare, bruchsichere Form zusammenlegen.In the case of the grinding wheel forming the subject of the invention, this disadvantage becomes apparent avoided in that their abrasive coating is made in several parts and on a holding the parts together flexible base is attached. With this division, the disk can be converted into an easily dispatchable, unbreakable one Collapse form.
Auf der Zeichnung ist eine Ausführungsform des Erfindungsgegenstandes dargestellt, und zwar zeigtThe drawing shows an embodiment of the subject matter of the invention, namely shows
Fig. ι eine Draufsicht,Fig. Ι a plan view,
Fig. 2 einen Querschnitt in der ausgebreiteten Lage,2 shows a cross-section in the expanded position,
Fig. 3 eine Ansicht der zusammengelegten Scheibe.Fig. 3 is a view of the collapsed disk.
Die Scheibe besteht in an sich bekannter Weise aus dem Belag a, der bei dem dargestellten Beispiel durch geradlinige Aussparungen oder Furchen b und d in drei Teile i, 2, 3 zerlegt und auf der üblichen Faserstoffunterlage f befestigt, beispielsweise aufgekittet ist. Zum Verschicken der Scheibe werden dieTeile 1 und 3 in der aus Fig. 3 ersichtlichen Weise auf den Teil 2 umgelegt, so daß die Scheibe auf die Abmessung des Teiles 2 zurückgeführt ist. Hierdurch wird eine ganz wesentliche Erhöhung der Widerstandsfähigkeit gegen Bruch und eine bessere Ausnutzung des Packraumes bei Verminderung der Pack- und Verschickungskosten erzielt. Trotz der Unterteilung der Scheibe hat sich ihre Festigkeit beim Schleifen als ungemindert erwiesen.The disc consists in a manner known per se from the covering a, which in the example shown is broken down into three parts i, 2, 3 by straight recesses or grooves b and d and attached to the usual fiber base f , for example cemented. To send the disc, parts 1 and 3 are folded over onto part 2 in the manner shown in FIG. 3, so that the disc is returned to the dimensions of part 2. This results in a very substantial increase in the resistance to breakage and better utilization of the packing space while reducing packing and shipping costs. Despite the subdivision of the wheel, its strength has proven to be undiminished during grinding.
