ABSTRACT:
An abrading device comprising one or more abrasive belt aggregates consisting of an endless abrasive belt passed along guide rollers and a pressing table arranged at a distance above the same in a resilient manner as well as elements for adjusting the distance between the pressing table and the abrasive belt, wherein the pressing table adjustable by setting elements is constantly loaded in a sense away from the abrasive belt by a compensating device neutralizing the weight of the table; owing to the compensating device the pressing table is constantly loaded against gravity so that the amounts of play are eliminated in a direction away from the abrasive belt.
The adjustment of the pressing table can then be performed so that the work piece is machined with an optimum effect.
