Abstract
A cross-grooved banded drive belt wherein a plurality of V-belt elements are retained in laterally spaced relationship by a tie band. The V-belt elements are provided with transverse grooves which, in the illustrated embodiment, are aligned across the belt and arranged in sets spaced longitudinally of the belt. The grooves are asymmetrical in longitudinal section and in the illustrated embodiment, include planar, leading, and trailing surfaces. In the illustrated embodiment, the leading groove surfaces have a greater length than that of the trailing surfaces. As a result of the transverse alignment of the grooves of each set, the leading surfaces are effectively coplanar with each other and the trailing surfaces are effectively coplanar with each other. Illustrative ranges of the angularity of the groove surfaces are disclosed. In one form, the sets of grooves are uniformly longitudinally spaced, and in another form, the sets of grooves are randomly differently spaced.
