ABSTRACT:
A pack unit containing fill material is mounted on a hub structure of a rotary finishing wheel having a rotary axis. The pack unit includes a rigid unitary elongated clip member to which the fill material is secured and a flexible plastic unitary elongated link member coextensive in axial length with the clip member and fill material and which includes inner and outer end portions connected by an intermediate flexible solid web portion. The end portions of the link member are provided with enlarged head portions, the inner head portion being adapted to be carried by a slot formation in the hub structure and the outer head portion being received in a mating slot provided in the clip member. When the pack unit is mounted on the hub structure, the flexible web portion of the link member appreciably flexes or bends without stretching or fatiguing when a force is applied to the fill material which swings the clip member and fill material to one side or the other of a radially extending plane containing the rotary axis and the axis of the inner head portion.
