Abstract
A noise-free silencer assembly is provided that is suitable for reducing self-vibration noises and screeching noises between a cleaning blade and the imaging member of an electrostatographic reproduction machine. The noise-free silencer assembly comprises a C-shaped cross-section elongate member having (a) a longitudinal axis, a wall defining an interior cavity for containing at least a partially compressed high density polymeric open cell foam, (b) a slot formed in the wall extending generally longitudinally and at an angle to the longitudinal axis of the C-shaped cross-section member, and (c) a hinge recess also formed in the wall extending generally longitudinally, for reducing self-vibration noises and screeching noises between a cleaning blade and an imaging member of an electrostatographic reproduction machine.
