A wire conveyor belt includes a plurality of spaced, tractive rods disposed in succession and transversely with respect to a direction of travel of the belt, each rod having two ends. A plurality of rows of wickets are transversely disposed with respect to the direction of travel, and interconnect the succession of rods, each row of wickets including a plurality of links, each link connecting a rod with a following rod in the succession. The belt has a transport course including at least one course turn deviating in a direction selected from the group consisting of a left course turn and a right course turn. The belt in the course turn has an outside edge and an inside edge, and the belt has a straight transport course downstream of the course turn. The belt in the straight transport course has an outside edge corresponding to the outside edge of the belt in the course turn, and the belt in the straight transport course has an inside edge corresponding to the inside edge of the belt in the course turn. At least one sprocket engages the rod in the straight transport course downstream of the course turn at a sprocket-engagement location on the belt inward of the outside edge. Tension in the belt is transferred so as to alleviate wicket fatigue failure. The tension is transferred by either: a) a split between adjacent links in each row of wickets, the split in each row being located between links of each row immediately adjacent the sprocket-engagement location on the belt; b) a tension-transferring combination of sprockets made up of a pair of sprockets including the sprocket described above, engaging the rods at immediately adjacent sprocket-engagement locations; c) at least one tension-transferring generally U-shaped tension link adjacent each row of wickets and connecting one rod in the succession with a following rod in the succession, the tension link being positioned between the outside edge and an outside end of a respective wicket row, wherein a base portion of the U-shaped tension link engages one rod in the succession and two leg portions of the U-shaped tension link engage an adjacent rod in the succession and d) a combination thereof. The present invention also relates to a process for transferring tension in a wire conveyor belt utilizing the features set forth above. |
