ABSTRACT:
A driving belt of the type comprising an endless carrier supporting a plurality of transverse elements is disclosed. The element includes at least one recess for receiving the carrier and is provided with a convex surface in the longitudinal and transverse directions for contacting the carrier. A method and apparatus for producing the curved surface includes a stationary hollow cylindrical grinding wheel and an apparatus for moving the element in an arcuate path while contacting the grinding wheel. An alternative embodiment provides for the element to remain stationary and the rotating grinding wheel moving in an arcuate path to produce the convex surface.
