Abstract
Abstract The rotary finishing wheel comprises a rotatable hub structure having an axis and includes an axially extending hub sleeve having a pair of radially outwardly extending flanges and a series of circumferentially spaced and axially extending mounting pins carried on the flanges adjacent the outer periphery thereof. Pack units are mounted on the pins and extend radially outwardly of the hub structure. Each of the pack units comprise a flap-like member of fill material presenting a radially outer finishing portion, and a mounting member distinct from the flap-like member for mounting the latter on one of the pins of the hub structure between the flanges. The mounting member is a relatively rigid unitary one having a single radially inner and axially extending portion or body formed with an opening of one of several shapes which telescopes axially onto one of the pins and wraps around the pin so that undesirable radial separation between the pin and the rigid body of the pack unit is prevented. The mounting member includes a pair of integral, radially outer and outwardly extending arm formations on the inner portion or body and coextensive therewith in overall length. The radially inner portion of the flap-like member is located between and is secured to the arm formations by staples or other fastening elements which clamp the arm formations against the fill material therebetween. The pack units may be mounted for pivotal movement on the pins of the hub structure and may be readily removable therefrom for replacement upon expected wear by the separation of component parts of the hub structure.
