Abstract
Abstract Circumferentially spaced finishing packs or fills each include an extruded length of stock which in one embodiment is a forked clip mount clamping a stack of abrasive sheets as part of the pack. In another embodiment, it is a mount in a simpler form of extrusion cross-section having a portion embedded in the stack. In either form, it has an integral, radially inwardly extending mounting element of key-like cross-section presenting an enlarged cylindrical bead or pin portion, which in some installations and as herein illustrated has a radially slidable mating and pivotal interfit in axially registered keyhole recesses of a hub of the wheel. These pack mounts are preferably extrusion molded and have axially spaced neck portions formed therein and integrally connecting the stack-engaging portion with the pin or bead portion. For installations of the sort described, the axial width of the neck portions of the extrusion is a trifle less than that of the axial spacing of certain radial disc-like rib formations of the hub between which said formations lie in use. Hence each finishing pack may in such case swing freely in use about the axis of the mounting bead of the extrusion. In other cases the pivotal action may not be present.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
142 words
A finishing unit comprising fill material to be mounted in a position radially outwardly of the axis of a rotary driver structure, and a unitary member for supporting and so mounting said fill material on such structure, said member being in a solid cross-section throughout in a plane at 90* to said axis as thus mounted and presenting a radially outer portion secured to said material, a radially inner, axially extending and transversely enlarged bead-like mounting portion integral with said outer portion and adapted for a mating engagement with said driver structure, and an intermediate neck portion integrally connecting said bead-like and radially outer portions, said neck portion having at least one opening between integral axially spaced neck elements thereof to afford clearance for a free swing of said unitary member on said driver structure about said beadlike portion as an axis.
Claim 2
Dependent Claim
142 words
A finishing unit comprising fill material to be mounted in a position radially outwardly of the axis of a rotary driver structure, and a unitary member for supporting and so mounting said fill material on such structure, said member being in a solid cross-section throughout in a plane at 90* to said axis as thus mounted and presenting a radially outer portion secured to said material, a radially inner, axially extending and transversely enlarged bead-like mounting portion integral with said outer portion and adapted for a mating engagement with said driver structure, and an intermediate neck portion integrally connecting said bead-like and radially outer portions, said neck portion having at least one opening between integral axially spaced neck elements thereof to afford clearance for a free swing of said unitary member on said driver structure about said beadlike portion as an axis.
Claim 3
Dependent Claim
152 words
A finishing unit comprising fill material to be mounted in a position radially outwardly of the axis of a rotary driver structure, and a unitary member for supporting and so mounting said fill material on such structure, said member being in a solid cross-section throughout in a plane at 90* to said axis as thus mounted and presenting a radially outer portion secured to said material, an intermediate neck portion, and a radially inner, axially extending and transversely enlarged bead-like mounting portion integral with said outer portion and neck portion, said neck portion and bead-like mounting portion being shaped for an axially sliding mating engagement with a correspondingly sectioned opening of said driver structure, said neck portion having at least one opening between integral axially spaced neck elements thereof to afford clearance for a free swing of said unitary member on said driver structure member about said bead-like portion as an axis.
Claim 4
Dependent Claim
152 words
A finishing unit comprising fill material to be mounted in a position radially outwardly of the axis of a rotary driver structure, and a unitary member for supporting and so mounting said fill material on such structure, said member being in a solid cross-section throughout in a plane at 90* to said axis as thus mounted and presenting a radially outer portion secured to said material, an intermediate neck portion, and a radially inner, axially extending and transversely enlarged bead-like mounting portion integral with said outer portion and neck portion, said neck portion and bead-like mounting portion being shaped for an axially sliding mating engagement with a correspondingly sectioned opening of said driver structure, said neck portion having at least one opening between integral axially spaced neck elements thereof to afford clearance for a free swing of said unitary member on said driver structure member about said bead-like portion as an axis.
Claim 5
Dependent Claim
21 words
The finishing unit of claim 1, in which said three portions are components of an extruded axially elongated length of stock.
Claim 6
Dependent Claim
33 words
The finishing unit of claim 2, in which said three portions are integral components of an extruded axially elongated length of stock, said member being substantially coextensive axially overall with said fill material.
Claim 7
Dependent Claim
26 words
The finishing unit of claim 1, in which said radially outer portion of said mounting member has forked arms between which the fill material is clamped.
Claim 8
Dependent Claim
26 words
The finishing unit of claim 2, in which said radially outer portion of said mounting member has forked arms between which the fill material is clamped.
Claim 9
Dependent Claim
29 words
The finishing unit of claim 1, in which said radially outer portion of said mounting member has an integral coplanar plate element by which the fill material is carried.
Claim 10
Dependent Claim
29 words
The finishing unit of claim 2, in which said radially outer portion of said mounting member has an integral coplanar plate element by which the fill material is carried.
Claim 11
Dependent Claim
69 words
The combination in a finishing wheel of a circumferential series of finishing units each in accordance with claim 1, and a driver structure as therein referred to, said structure being provided with a series of like circumferentially spaced sets of aligned openings paralleling the axis of the driver structure, in each of which sets the bead-like mounting portion of a finishing unit is mounted with a substantially mating fit.
Claim 12
Dependent Claim
117 words
The combination in a finishing wheel of a circumferential series of finishing units each in accordance with claim 2, and a driver structure as therein referred to, said structure being provided with a series of like circumferentially spaced sets of aligned openings paralleling the axis of the driver structure, in each of which sets the bead-like mounting portion of a finishing unit is slidably mounted with a substantially mating fit, said driver structure having at least one radially outwardly extending rib formation having said openings and being straddled by axially spaced neck elements of said neck portion of the mounting member, said units being pivotal relative to said driver structure about individual axes of said bead-like portions.
