Flange turner with dampening device

摘要

An apparatus for rotating elongated members of rectangular cross section, such as board lumber, is disclosed. The apparatus includes a pair of conveyors arranged so that the boards will cascade from the end of one conveyor onto the other conveyor by force of gravity, rotating in the process. A dampening mechanism to reduce the impact caused by the fall is also disclosed. The dampening mechanism allows the members to be delicately balanced on any side. After an inspection, the boards are turned again to position them for final processing. This second rotation is performed by halting the leading edge ofthe boards, at either the top or bottom, and propelling the opposite edge forward with a rubber wheel.
