摘要

The machine has a frame, and a grinding wheel shaft carrying a grinding wheel (6) slidingly mounted in a sheath. Reference rollers (16, 16a) are arranged on telescopic arms (17, 17a), respectively, in slidingly in supports (18, 18a) integrated to the frame for permitting a transition of the rollers in a direction of upstream and downstream rails. Flywheels (19, 19a) block the rollers in a position. The grinding wheel is protected on three sides by the frame whose section is in form of U.
