Abstract:
1. A positioning apparatus for use with a rotary fence, wherein the rotary fence includes a board stop coupled with a continuous track loop, the continuous track loop is operable in a first direction of flow and the board stop is movable relative to the continuous track loop in a second direction that is transverse to the first direction of flow, the positioning apparatus comprising: a positioning guide with guide surfaces configured to engage the board stop, the guide surfaces including a lateral guide surface oriented transverse to the first direction and a plurality of longitudinal guide surfaces arranged at intervals along the lateral guide surface, the longitudinal guide surfaces defining a corresponding plurality of first lateral positions, wherein the positioning guide is operable to divert the board stop from the lateral guide surface to a selected one of the longitudinal guide surfaces to position the board stop at a corresponding one of the first lateral positions; and a shifting member coupled with a downstream end of the positioning guide, the shifting member configured to laterally displace a downstream end of the longitudinal guide surfaces to move the board stop to a second lateral position between adjacent ones of said first lateral positions.
