ABSTRACT:
There is provided a surface-dressing tool for petrous materials exhibiting a better bite for a lower sound level and a lower energy consumption in that it comprises a pair of cylindrical surface-dressing rollers mounted rigidly on the ends of axles extending parallel between them. The driving force on a pair of rollers on one and the same axle is the resultant of the friction components of opposite sign of each roller in relation to the working surface.
