A rotary stripper comprising a pair of spaced plates driven around a shaft and studs extending between the plates and radially spaced from the shaft; stripper members, each comprising generally hairpin shaped members, with the bend mounted around a stud and the legs extending past the shaft and beyond the periphery of the plates; the legs of each stripper member are respectively supported against excessive deflection by the drive shaft and on the other studs; retainer studs are provided radially outside the mounting studs to block separation of the stripper members from their respective mounting studs; the stripper members are laid down on annularly successive studs until the required height of the stripper is reached, whereby the stripper members are interleaved.

A flexible polishing drum segment for use with a polishing or grinding hub. The segment comprises a plurality of abrasive flaps of uniform size and shape, joined together along a common edge to a metal strip. The metal strip comprises first and second, substantially flat plate sections extending parallel to one another in surface-to-surface abutment. One of the plate sections is longer than the other and it is to this longer plate section that the packet is joined. The first and second plate section are integral with and joined together by a root element which is generally circular in configuration. A core is located within the root element to substantially fill the entire volume thereof.

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.

The wheel comprises a pad-mounting structure constituted by an axially spaced series of split circular disc-like plate units of aluminum which are coaxially and releasably clamped rigidly to a wheel driving shaft at the ends and between the ends of said structure. Each such plate component is comprised of two substantially identical semi-circular plate halves which directly clamp releasably to the shaft, the plate pairs at axial ends of the assembly each being supplemented by a further similar split plate or disc unit located just axially inward thereof. All except the two endmost of said split plate units are provided with an annular series of equally spaced holes closely adjacent their outer periphery, which holes slidably receive elongated rods paralleling the shaft axis, upon which axially aligned sets of flexible finishing pads or packs of the wheel are mounted for a very free-swinging action. However, the endmost plates are imperforate in said peripheral zone; and either one or both halves of an endmost plate unit may be taken off the wheel shaft if the finishing pad is to be removed and replaced, as accommodated by an axial sliding movement of a pivot rod. Each half of each split plate unit is provided at its diametral zone with a thickened axial boss or hub formation presenting a semicylindrical seat; and said seats center on the wheel shaft when said halves are releasably bolted to the shaft at said bosses thereof.

The rotary flap or finishing wheel or tool has a plurality of radially extending finishing units or packs mounted in a circumferential series on a hub structure. The finishing units are mounted on the body structure by a dual clip-type assembly including an inner axially elongated and rigid clip member forming the primary component of the pack and an axially elongated outer clip member supporting or carrying the finishing or fill material and forming the secondary components of the finishing unit. The mount of the inner clip member is afforded at an inner axially extending through-bore therein which encircles an axial pin component located adjacent the outer periphery of the hub structure. The inner clip member has an axially elongated, keyhole-type slot or groove that opens re-entrantly along the entire axial length of the outer free clip end. Replaceable units of fill or finishing material are each constituted in part by the secondary or outer clip component or member having radial arms which are coextensive in axial length with the finishing material and are stapled in place within the latter. The arms integrally connect with one another at a radially inner bight at which, along with a telescoped inner wear sleeve, the pre-assembled finishing unit-secondary clip member is telescoped into the re-entrant keyhole recess of the primary clip member. Either one or both of the clip members of each finishing unit are mounted for pivotal movement.

A plurality of pre-assembled abrasive units are removably mounted on the periphery of a cylindrical but, and each includes a pad of multiple abrasive-coated plies fastened together at their inner ends by an anchor clip formed for retention in slots in the hub. Each overlying ply is of successively shorter length, and the plies form at their outer ends multiple stepped abrading surfaces which define a self-dressing finishing surface for rotation against the work surface. The plies are bowed into an arcuate shape and a predetermined flexibility to maximize the exposed finishing surface and soften it for improved abrading and service life characteristics.
摘要:
An improved and specialized type of construction for an abrasive drum of the type in which a plurality of abrasive packs are mounted in uniform circumferential spacing around the entire cylindrical surface of a central hub, the hub being provided with longitudinal mounting slots, one for each pack. The abrasive drum of the invention combines a hub construction in which the slot sidewalls diverge continuously from a relatively wide slot opening, with abrasive packs, each of which is comprised of a number of abrasive strips joined at their base edge to form a substantially flat base seating on the cylindrical surface of the drum; and each pack is provided with a resiliently deformable plastic retainer which is molded in cross section to provide an anchoring rod portion retained in said slot by said slot sidewalls, and a radial web portion extending from said rod into said pack of abrasive strips, said rod having a transverse dimension substantially less than the width of said slot to permit hinge action of said packs on said hub during rotation of said abrasive drum.
