Abstract
In a belt and pulley system wherein motion is transferred between the two members, the belt is a metal belt having a pulley engaging face made of a relatively soft material and the pulley is one having a regular pattern of small hard protuberances, such as formed by knurling, on its belt engaging face which press into the soft metal of the belt to form permanent depressions arranged in a matching pattern which mesh with the protuberances to provide a positive slip-free motion transfer. The belt and pulley drive may be used advantageously in a device such as an X-Y plotter for accurately positioning, with good repeatibility and fine resolution, an associated member driven in one coordinate direction by the metal belt driven in turn by the knurled pulley.
