Abstract
A conveyor belt includes a self-supporting linkage assembly and a plurality of transverse elements configured to travel along a longitudinal direction. The transverse elements are interconnected by the linkage assembly. The conveyor belt also includes a biasing member. The linkage assembly includes a first link and a second link. The first and second links are configured to move relative to each other between an engaged position and a disengaged position. The biasing member is configured to bias the first and second links toward the engaged position. The first and second links, when in the engaged position, are constrained against rotation relative to each other. The first and second links, when in the disengaged position, are configured to rotate relative to each other.
