Abstract: The invention relates to an apparatus for treating blocks, having a conveying arrangement for transporting the blocks one after the other along a treatment station in which there is arranged at least one tool holder which can be driven in circulation by means of a drive, has a longitudinal axis and on which there are fastened flexible, elongate treatment tools which have two ends and come into contact with predetermined regions of the blocks as the tool holder circulates. The flexible treatment tools are fastened in loop form, by way of the two ends, on the tool holder such that they are spaced apart from one another in the direction of the longitudinal axis of the latter, with the result that they sag when the tool holder is at a standstill.
