When a TAB assembly is used in the transfer station of an electrostatic marking system, the blade used in the TABs becomes deformed or improperly aligned due to lateral movement of the clamp, held by rivets, which is used to maintain proper blade alignment. Provided herein is a simple, yet effective, way to secure this clamp with embedded burrs so that the useful life of the TAB is more than doubled over prior art TABs.
