Abstract: A bowing press apparatus which includes a subassembly. The subassembly comprises a housing, a mandrel supported by the housing, a wiper plate connected to said housing and capable of pivoting with respect to said mandrel, and an actuator that exerts a force against the wiper plate, causing the wiper plate to pivot. An overbender capable of pivoting with respect to the mandrel and the wiper plate may be connected to the wiper plate. An actuating device that exerts a force against the overbender and causes it to pivot also may be included.

Abstract: A variable radius bowing press including a mandrel, a mandrel support and a subassembly. The subassembly comprises a housing, a wiper plate capable of pivoting with respect to the mandrel, and an actuator that exerts a force against the wiper plate, causing the wiper plate to pivot. An overbender capable of pivoting with respect to the mandrel may be connected to the wiper plate. An actuating device may be provided that exerts a force against the overbender and causes the over bender to pivot. The apparatus may include two substantially similar subassemblies capable of synchronized operation.
