Abstract
A transfer tail assembly for use with a conveyor assembly that adjust the tension in the conveyor belt. The transfer tail assembly includes a pair of adjustment brackets that are each movable along a conveyor axis and support an end roller. The movement of the adjustment brackets and the end roller adjust the tension in the conveyor belt. A spiral cam is positioned such that rotation of the spiral cam causes movement of the end roller along the conveyor axis. A drive pin of the adjustment bracket moves along a spiral cam contact surface. The end roller is pivotable relative to the conveyor frame to release tension on the conveyor belt. The final position of the end roller can be adjusted using a pivot limiting bar.
