ABSTRACT:
A conveyor chain has longitudinally elongated coupling links having transverse throughgoing bores and longitudinally elongated entrainment links each formed with a transversely throughgoing window having a relatively wide central section and a pair of opposite relatively narrow end sections centered on respective parallel and transverse axes. Respective coupling pins have central regions of a cross-sectional size that can fit axially through the central section but not through the end section of the respective entrainment link and ends formed with axially limited regions of reduced cross-sectional size interfittable with the ends of the windows. These limited regions have end faces axially flanking the respective entrainment link. Thus the pins pivotally connect the links together into an annular succession with the entrainment and coupling links normally alternating with each other. Respective entrainment devices extend axially through the windows between the respective pins and are of a dimension measured in the plane of the respective axes that is generally equal to the spacing between the pins when same are engaged in the respective end sections and are generally centered on the respective axes. The entrainment devices are each secured against axial movement relative to the respective entrainment links.
