ABSTRACT:
A pack unit adapted to be mounted on the hub structure of a rotary finishing wheel. The hub structure includes a plurality of circumferentially spaced, elongated slots about the periphery thereof and each of the slots has an inner portion, a restricted neck passage opening outwardly therfrom, and a longitudinal slot axis substantially parallel to the rotational axis of the finishing wheel. The pack unit includes at least one flap-like member of finishing material having a radially outer portion adapted for engaging a workpiece and a radially inner portion adapted to be clampably secured. The pack unit includes an improved mounting apparatus which includes a unitary, integrally-formed, elongated clip member which includes a clip body and a pair of radially outwardly extending clamping arms adapted for clampably receiving the radially inner portion of the flap-like member therebetween. The radially inner portion of the clip body is provided with an elongated, radially inwardly disposed slot having an inner portion and a restricted neck passage opening outwardly therefrom. The improved pack unit mounting apparatus includes a unitary link member having a first slot-engaging head portion adapted to be telescopically received within the elongated slot of the clip member, a second slot-engaging head portion adapted to be telescopically received within an elongated slot of the hub structure, and an intermediate portion integrally connecting the head portion. End segments of the intermediate link portion adjacent the head portions are adapted to be telescopically received within the restricted neck passages of the slots such that the link member telescopically and replaceably mounts the flap-like members to the hub structure for limited hinge-type pivotal movement about the slot axii.
