A method of forming a power transmission belt including the steps of: providing a belt sleeve defining an axis and having a rubber layer with elongate fibers embedded therein and extending generally parallel to each other in a first line; rotating the belt about its axis; providing a grinding element for cutting the rubber layer and fibers to define ribs with oppositely facing flanks; and urging the rotating belt sleeve and grinding element, one against the other in first and second steps and, as an incident thereof, causing the grinding element to define the oppositely facing flanks. The belt sleeve and grinding element are urged one against the other transversely of the first line at a first speed during the first step and at a second speed different than the first speed during the second step.
