ABSTRACT:
A conveyor frame assembly for use with a conveyor belt formed from individual links each joined together at pivot points. The conveyor frame assembly includes a drive assembly that pulls the conveyor belt around a drive roller to transition between the upper and lower runs of the conveyor belt. The drive end includes a support block that encloses the side edges of the conveyor belt as the conveyor belt transitions over the drive sprockets. The side frame members each include a continuous retaining channel having a height greater than the thickness of the conveyor belt. The retaining channels formed on opposite sides of the conveyor frame assembly allow the lower run of the conveyor belt to “tent” by creating an angle between adjacent links of the conveyor belt assembly. The tenting of the lower run of the conveyor belt eliminates catenary sag.
