Patent ID: 8087278

Claim:
An apparatus for forming a mounting flange on a printing plate, the apparatus comprising a bending device, the bending device comprising: a supporting bed having a working surface that can position and support a printing plate relative to the bending device; a first anvil comprising a first forming surface having a first radius, the first anvil positioned relative to the working surface of the supporting bed so a printing plate positioned on the working surface of the supporting bed can be bent around the forming surface of the first anvil to form a flange on the printing plate; a clamping device positioned relative to the working surface of the supporting bed, the clamping device having a clamping surface movable between a first unclamped position where the clamping surface is spaced apart from the working surface of the supporting bed and a second clamped positioned where the clamping surface can contact a printing plate positioned on the working surface of the supporting bed to hold the printing plated during a bending operation to form a flange on the printing plate; a mandrel positioned relative to the first forming surface of the first anvil, the mandrel having a body portion and a working surface capable of being controllably rotated about the first forming surface of the first anvil to form a flange on a printing plate when positioned on the working surface of the supporting bed and held by the clamping device; a second anvil comprising a second forming surface having a second radius different from the first radius of the first forming surface of the first anvil, the second anvil moveable relative to the first anvil between a first retracted position where the first anvil is used to form a flange on a printing plate and a second working position where the second anvil is used to form a flange on a printing plate; and a control system that controls operation of one or more of the clamping device, mandrel, and second anvil.
