Bei Schleif- und Polirtrommeln macht sich auf unangenehme Weise der Uebelstand bemerkbar, dafs bei schneller Rotation dieser Trommeln der si& umgebende, aus Feuerstein-, Schmirgel-, Filz- oder anderen Streifen bestehende Mantel beim Heranhalten der zu schleifenden Gegenstände, z. B. von Filzhüten, sich verlängert, so dafs ein Lockerwerden, Aufeinanderschieben bezw. Zerreifsen stattfindet und durch die sehr häufige Erneuerung dieser Streifen viel Zeitverlust entsteht.In the case of grinding and polishing drums, the inconvenience is noticeable in an unpleasant way, that with rapid rotation of these drums the surrounding flint, Emery, felt or other strips of existing coat when holding the to abrasive objects, e.g. B. of felt hats, lengthened, so that a loosening, Pushing on top of each other or Tearing takes place and due to the very frequent renewal of this Streak a lot of time loss occurs.
Genanntem Uebelstand soll durch die nachstehend beschriebene neue Einrichtung, welche in den beiliegenden Zeichnungen veranschaulicht ist, begegnet werden.The above-mentioned inconvenience is alleviated by the new device described below, which illustrated in the accompanying drawings.
Auf diesen zeigt:This shows:
Fig. ι die Seitenansicht einer Schleiftrommel mit umgelegtem Schleifmantel nach Entfernung der Deckplatte undFig. Ι the side view of a grinding drum with the grinding jacket folded over after removal the cover plate and
Fig. 2 einen Querschnitt durch die Schleiftrommel. Fig. 2 shows a cross section through the grinding drum.
Die Trommel B besitzt an einer Stelle der Umfläche einen Spalt, in welchen die Enden des in Breite der Trommel zugeschnittenen Schleifstreifens gesteckt werden. Neben diesem Spalt ist an der inneren Umfläche mittelst Schrauben α ein feilklobenartiger Streifenhalter C gelagert, dessen Backen an dem nach der Mitte gebogenen Bolzen E geführt werden. Der Streifenhalter C ist an einem die Schleifwelle umspannenden Doppelbügel F verbolzt, welcher an der entgegengesetzten Seite der inneren Umfläche mittelst Federn d elastisch gelagert ist. Die Enden dieses Doppelbügels F werden durch einen Schraubenbolzen zusammengehalten , an welchem zugleich ein durch Gewicht G belasteter, an der Seitenwandung der Trommel bei J drehbar gelagerter Hebel H befestigt ist, welcher durch die Deckplatte P hindurchreicht und für den in der letzteren, damit er dem Zug der Federn d folgen kann, ein Führungsschlitz vorgesehen ist. Gegenüber dem Streifenhalter C besitzt die Deckplatte P einen Ausschnitt, damit man zu jeder Zeit bequem zu der FlUgelschraube des Bolzens E gelangen kann.The drum B has a gap at one point on the circumferential surface, into which the ends of the grinding strip cut to the width of the drum are inserted. In addition to this gap, a hedge-like strip holder C is mounted on the inner surface by means of screws α , the jaws of which are guided on the bolt E , which is bent towards the center. The strip holder C is bolted to a double bracket F which encompasses the grinding shaft and which is elastically mounted on the opposite side of the inner peripheral surface by means of springs d. The ends of this double bracket F are held together by a screw bolt to which at the same time a weight G loaded lever H rotatably mounted on the side wall of the drum at J is attached, which extends through the cover plate P and for the one in the latter, so that he the Train the springs d can follow, a guide slot is provided. Opposite the strip holder C, the cover plate P has a cutout so that the wing screw of the bolt E can be easily reached at any time.
Nach Umlegen des Schleifstreifens A um die Trommel B werden die Enden des Streifens durch den Spalt in der Umfläche gesteckt und zwischen die Backen des Streifenhalters C gezogen, woran sie unter gleichzeitiger geringer Anspannung der Federn dd durch die FlUgelschraube und den excentrischen Bolzen E so festgespannt werden, dafs der Streifen, wenn die Trommel in Ruhe ist, dieselbe fest umschliefst. Während der darauf stattfindenden schnellen Drehung der Trommel wird der Streifen durch den Halter C, den damit verbundenen Doppelbügel F und den Gewichtshebel H vermöge der Fliehkraft selbsttätig gespannt.After placing the grinding strip A around the drum B , the ends of the strip are pushed through the gap in the surrounding area and pulled between the jaws of the strip holder C , whereupon they are tightened by the wing screw and the eccentric bolt E while the springs dd are slightly tensioned so that when the drum is at rest the strip encloses it tightly. During the rapid rotation of the drum that then takes place, the strip is automatically tensioned by the holder C , the associated double bracket F and the weight lever H by virtue of the centrifugal force.
