ABSTRACT:
The invention provides a uni-flex belt which can bend only in one direction and which has particular utility in treadmills. The uni-flex belt of the invention comprises a continuous loop having an outer portion and a non-stretchable inner portion attached to one another. The outer portion comprises a multiplicity of abutting transverse rigid tread segments which extend across the belt and which have sides substantially parallel to one another. The tread segments press together and are laterally compacted during operation of the belt to provide a substantially smooth outer surface and to cooperate with the inner portion to prevent the belt from sagging or bending in the other direction.
