Abstract
A link member having a curved bearing surface and a conveyor belt comprising a link member having a curved bearing surface are described. The link member can be comprised in any type of conveyor belt, including a grid-type conveyor belt, a smaller-radius grid-type conveyor belt or a flat-wire conveyor belt. The link member eliminates the objectionable noise caused by pivot rods jumping the corner of conventional links having curved bearing surfaces. According to one embodiment, the link member comprises a pair of leg portions, each leg portion comprising a first opening at a distal end and a second opening at a proximal end, and a connecting portion that connects the pair of leg portions, the connecting portion comprising a curved bearing surface between first and second side surfaces. The first and second side surfaces extend in a direction toward the proximal end of the leg portions.
