Description

Es ist bereits bei Vorrichtungen zum Schleifen oder Polieren mit einem umlaufenden endlosen Band bekannt, den jeweils auf dem zu bearbeitenden Werkstück aufliegenden und durch die Führungs- und Antriebsrollen gespannten Teil- des Bandes dadurch zum besseren Aufliegen zu bringen, daß oberhalb dieses Bandteiles unter regelbarem Federdruck stehende Stücke angeordnet werden, die auf dem Band flach aufliegen. Zur Vermeidung der sich hierbei ergebenden großen Reibungsarbeit sowie zur Erzielung eines über die ganze Auflagestelle möglichst gleichmäßigen Anpreßdruckes werden gemäß der vorliegenden Erfindung die Preßstücke als Rollen in Gestalt von drehbar gelagerten Luftkissen (Luftreifen) ausgeführt, so daß zwischen Band und Anpreßstück nur rollende, aber keine gleitende Reibung entsteht. Der Anpreßdruck bzw. die Anpreßfläche kann hierbei durch Bemessung des Luftdruckes reguliert werden. Es wird ferner bemerkt, daß unmittelbar mit ihrer Oberfläche arbeitende Schleif- und Polierscheiben in Gestalt von luftgefüllten Reifen oder Trommeln auch schon bekannt sind und nur die Verwendung solcher Reifen oder Trommeln als Mittel zum Andrücken des endlosen Bandes auf die zu bearbeitende Oberfläche als neu beansprucht wird.It is already in the case of devices for grinding or polishing with a rotating endless belt known, each resting on the workpiece to be machined and Part of the belt tensioned by the guide and drive rollers thereby for the better To bring that above this band part under adjustable spring pressure Pieces are arranged that lie flat on the belt. To avoid the great amount of friction that results as well as to achieve a contact pressure that is as uniform as possible over the entire contact point According to the present invention, the pressed pieces are as rolls in the form of rotatably mounted air cushions (pneumatic tires) executed so that only rolling, but not sliding, between the band and pressure piece Friction arises. The contact pressure or the contact surface can be regulated by measuring the air pressure. It is also noted that grinding and working directly with its surface Polishing discs in the form of air-filled tires or drums are also already known and only the use of such tires or drums as a means of pressing of the endless belt on the surface to be processed is claimed as new.

Die Zeichnung zeigt ein Ausführungsbeispiel der Erfindung.The drawing shows an embodiment of the invention.

Es bedeuten 1 die zu bearbeitende Oberfläche, 7 das umlaufende endlose Band, das über die Rollen 10 geführt ist, und 8 das drehbar gelagerte reifen- oder trommelartige Luftkissen. Statt eines solchen können auch mehrere verwendet werden.1 is the surface to be processed, 7 is the endless belt that runs around it is guided over the rollers 10, and 8 the rotatably mounted tire or drum-like Air cushions. Instead of one, several can be used.

Das rotierende Luftkissen kann beliebig unterteilt werden, und zwar bis zur Zellengröße von Zellkautschuk.The rotating air cushion can be divided as required, up to the size of the cell of cellular rubber.
