PATENTAMT.PATENT OFFICE.
Zu vielen Schleif zwecken, z. B. bei einigen Holz- und Metallbearbeitungen, sodann aber auch zum Schleifen von Häuten und Leder gebraucht man vorzugsweise Schleiftrommeln mit auswechselbarer Schleiffläche. Nun besteht namentlich bei Bearbeitung der letztgenannten Stoffe der große Ubelstand, daß sehr viel Staub entsteht, welcher nicht nur die Schleiffläche bald verschmiert, sondernFor many grinding purposes, e.g. B. with some wood and metal processing, but then Sanding drums are also preferably used for sanding hides and leather with exchangeable sanding surface. Now there is, in particular, the processing of the latter Substances the great disadvantage that a lot of dust arises, which not only the sanding surface soon smeared, but rather
ίο auch die Schleifarbeit selbst sehr erschwert. Man hat versucht, durch Anbringung besonderer Bürstenwalzen den Staub immer wieder von der Schleiftrommel zu entfernen, jedoch ohne hinreichenden Erfolg.ίο also makes the grinding work itself very difficult. Attempts have been made to remove the dust again and again by attaching special brush rollers removed from the sanding drum, but without sufficient success.
Vorliegende Erfindung bezweckt die Vermeidung aller dieser Übelstände durch eine eigenartige Einrichtung der Schleiftrommel. Auf dem Zylindermantel derselben sind nämlich eine große Anzahl von Bürsten (von verschiedenen Materialien) derart angeordnet, daß immer zwischen je zwei Bürsten ein Teil des Zylindermantels als Schleiffläche freibleibt. The present invention aims to avoid all of these inconveniences by one peculiar device of the sanding drum. On the cylinder jacket the same are namely a large number of brushes (made of different materials) arranged in such a way that that a part of the cylinder jacket always remains free as a grinding surface between every two brushes.
Auf der Zeichnung ist eine derartige Schleiftrommel in zwei Ausführungsformen dargestellt. In the drawing, such a grinding drum is shown in two embodiments.
Bei der Ausführungsform nach Fig. 1 und 2, welche eine Schleiftrommel in Querschnitt und Längenansicht zeigen, sind in dem Mantel α der Trommel winkelförmige Einschnitte in bestimmtem Abstand voneinander vorgesehen. In diese Einschnitte sind winkelförmige Bürsten b eingesetzt, deren Borsten die äußere Schleiffläche etwas überragen. Die Schleiffläche wird durch einen Überzug c 3; hergestellt. Derselbe besteht aus irgend einem Schleifmittel (Schmirgelleinwand, Glaspapier, Fischhaut, Schleifleder usw.), welches über die stehengebliebenen Schleifflächen d der Trommel α gelegt und durch die Bürsten 4t gleichzeitig mit festgeklemmt wird. Das Anziehen der letzteren kann durch beliebige bekannte Mittel geschehen.In the embodiment according to FIGS. 1 and 2, which show a grinding drum in cross-section and length view, angular incisions are provided in the shell α of the drum at a certain distance from one another. Angular brushes b , the bristles of which protrude slightly beyond the outer grinding surface, are inserted into these incisions. The grinding surface is covered by a coating c 3; manufactured. It consists of some kind of abrasive (emery canvas, glass paper, fish skin, sanding leather, etc.), which is placed over the remaining grinding surfaces d of the drum α and is clamped by the brushes 4t at the same time. Tightening of the latter can be done by any known means.
Bei der zweiten Ausführungsform, welche in Fig. 3 und 4 in Querschnitt und Längen- 4i ansieht dargestellt ist, laufen die Bürsten b nicht parallel der Erzeugenden des Zylindermantels, sondern nach der Mitte des Mantels winkelförmig. Außerdem haben die Bürsten nicht dreieckigen Querschnitt, son- 5c dem sie sind trapezförmig, was^jedoch in bezug auf die Wirkung gleichgültig ist. Die Befestigung kann beispielsweise durch einfache Flügelschraitben e erfolgen.In the second embodiment, which is shown in cross-section and lengthwise in FIGS. 3 and 4, the brushes b do not run parallel to the generatrix of the cylinder jacket, but at an angle towards the center of the jacket. In addition, the brushes do not have a triangular cross-section, but are trapezoidal, which, however, is irrelevant with regard to the effect. The attachment can be done, for example, by simple wing screws.
Die oben beschriebene Einrichtung eignet sich auch vorzüglich als Polierwalze, wobei natürlich statt des Schleifmittels ein Poliermittel zwischen den Bürsten einzuklemmen ist.The device described above is also ideally suited as a polishing roller, with Of course, instead of the abrasive, a polishing agent must be sandwiched between the brushes.
