Abstract
The invention provides a cover for an over-lapping conveyor belt joint. The cover prevents gaps between the belts at the joint and draws the bolt heads into a recess on the underside of the joint, thereby reducing belt jump as the bolt heads pass over the rollers.
The invention may also protect the leading edge of the upper belt. The invention is well suited to use on agricultural swath pick-ups such as those used on combines.

BACKGROUND
io Over-lapping conveyor belt joints are known and used in many applications.
In recent years agricultural swath pick-up belts have used the over-lapping joint wherein the two ends of the belt are over-lapped and bolted together. On the whale such a joint has been an improvement over the prior jciiung method of a pin through lacings on each end of the belt, rs A problem with the over-lapping jc~ini is that the bolls squash the belt, causzng the belt material to buckle and gap between the bolts. When used on an agricultural swath pick-up such as that used on combines, crop material becomes jammed in these gaps causing pressure and stress on the belt material. In other applications. material of various kinds zo c:auses tlxe sazoe prvblez~t. 'flae industry has used a stzaigbt plate over the gap in an attempt to remedy the problem with little success.
