Abstract

The contact pulley (1) supports an endless grinder belt (2), having a peripheral cushion (4) against which the belt runs and which contains supporting ribs (5) for the latter at intervals. The leading edges (6) on the ribs are at uneven intervals. The values of the latter can have no common denominator. The ribs can be of unequal widths, with slots (8) of equal width between them.
