Abstract:

An impacting mechanism for impacting a surface. An impacting mechanism having plungers spaced apart and adjacent allows fractured pieces to fly away and has a latch assembly that puts side loads on the plungers. An impacting mechanism having an impact plunger disposed in generally centered relation within a tubular actuator shields the impact to contain fractured pieces and provides a plurality of latch assemblies to equalize loading. The impacting mechanism breaks composite material into a plurality of pieces.
