ABSTRACT:
In order to prevent built up crusts on the flicker assembly from being detrimentally dislodged due to the cleaning fibers impacting the flicker bar assembly, there is provided a soft contact portion flicker bar assembly for mounting in a machine to contact and flick the cleaning fibers moving along a fiber path. The soft contact portion flicker bar assembly includes (a) a base portion for mounting to a frame portion of the machine; (b) a body portion including a distal, first end, and an opposite, second end connected to the base portion; and (c) a tip portion connected to the first, distal end for contacting and interfering with cleaning fibers moving along the fiber path. The tip portion is made of a material having a Shore A durometer hardness of less than 85 for reducing a jarring effect of impact forces between such tip portion and the moving cleaning fibers, thereby preventing detrimental dislodging of built up crusts of particles from any part of the flicker bar assembly.
