ABSTRACT:
Drive and related travel tension is decreased at selected locations in special purpose travel paths for woven-wire conveyor belts enabling decrease in tensile strength requirements of metal wire components as assembled into a woven-wire belt. Connector rod configurations with varying depth seats, at selected locations for individual helically-wound loops of interacting spiral wires, provide for expansion of belt length at selected locations where needed to decrease or eliminate metal wire component strain. In unitary vertically-oriented lateral edge portions of an assembled belt during endless-belt travel about cylindrical configuration support rolls, travel tension is decreased by providing for added belt length of such unitary vertically-oriented lateral edge means as used for confining articles being conveyed; and, to provide more efficient and effective application of dynamic frictional drive forces along the length direction of travel of an elongated assembled belt in a travel path which is laterally-curved in relation to such length direction while maintaining a substantially-horizontal conveyance surface.
