A grinding wheel for treating a surface of a power transmission belt/belt sleeve. The grinding wheel has a cylindrical body defining a rotational axis and having a circumferential outer surface with there being a plurality of abrading elements arranged in circumferentially spaced relationship on the outer surface of the body. Reliefs are provided between adjacent abrading elements. The invention further contemplates a method of treating a belt using the inventive grinding wheel.

Endless power transmission belt processing apparatus, a grinding wheel

An apparatus for limiting deviation of an endless belt/belt sleeve from a desired rotational path. The apparatus has first and second rollers each having a rotational axis and cooperatively supporting an endless belt/belt sleeve trained therearound for rotational movement in a predetermined path. A first member is mounted on one of the first and second rollers for movement axially relative to the one of the first and second rollers. A blocking structure defines a shoulder for engagement with an edge of an endless belt/belt sleeve trained around the first and second rollers to limit movement of an endless belt trained around the first and second rollers in a first axial direction relative to the one of the first and second rollers.
