Abstract
Abstract A roll having a curved stationary axle carries a series of bearings which rotatably mount a roller sleeve. The bearings, which have to fit the axle loosely, are held firmly in place by an axial stack of annular spacer collars and axially-compressible spring spacers, which apply a controlled compression. Optionally, deformable cushioning rings are compressed against the bearings by the collars. The cushioning rings may be made of a material which is either compressible or incompressible; the spacers have expansion chambers at their ends to accommodate deformation of the rings if these are incompressible.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
65 words
A roll comprising, in combination: an axle, a series of bearings received about said axle and axially spaced apart therealong, roller means rotatably supported on said bearings, spacer means arranged along said axle between said bearings, at least one of said spacer means being axially-compressible, and means for compressing said spacer means against said bearings to hold said bearings firmly in place on said axle.
Claim 2
Dependent Claim
65 words
A roll comprising, in combination: an axle, a series of bearings received about said axle and axially spaced apart therealong, roller means rotatably supported on said bearings, spacer means arranged along said axle between said bearings, at least one of said spacer means being axially-compressible, and means for compressing said spacer means against said bearings to hold said bearings firmly in place on said axle.
Claim 3
Dependent Claim
32 words
A roll as recited in claim 1, said axially-compressible spacer means comprising at least one annular disc bent to form lobes offset from the plane of the disc and circumferentially spaced thereabout.
Claim 4
Dependent Claim
24 words
A roll as recited in claim 2, said axially-compressible spacer means comprising a plurality of said bent annular discs arranged in a nested stack.
Claim 5
Dependent Claim
37 words
A roll as recited in claim 1, said axially-compressible spacer means comprising at least one annular spacer collar extending about said axle and having a series of circumferential slots extending partially through the diameter of said collar.
Claim 6
Dependent Claim
21 words
A roll as recited in claim 4, said slots being axially spaced apart and staggered about the circumference of said collar.
Claim 7
Dependent Claim
35 words
A roll as recited in claim 1, said spacer means further including a plurality of substantially incompressible annular spacer collars arranged along said axle in axially-stacked relation with said bearings and said axially-compressible spacer means.
Claim 8
Dependent Claim
12 words
A roll as recited in claim 1, said axle being longitudinally curved.
Claim 9
Dependent Claim
36 words
A roll as recited in claim 7, at least some of said spacer means being formed with mutually-engaging ball-and-socket joints whereby said spacer means are free to conform individually to the local curvature of said axle.
Claim 10
Dependent Claim
22 words
A roll as recited in claim 1, said compressing means adjustably engaging ends of said axle protruding axially from said roller means.
Claim 11
Dependent Claim
40 words
A roll as recited in claim 1, together with deformable cushioning means engaging said bearings, said compressing means being operable to compress said cushioning means against said bearings to assist in holding said bearings firmly in place on said axle.
Claim 12
Dependent Claim
18 words
A roll as recited in claim 10, said deformable cushioning means being formed of substantially compressible elastomeric material.
Claim 13
Dependent Claim
18 words
A roll as recited in claim 10, said deformable cushioning means being formed of substantially incompressible elastomeric material.
Claim 14
Dependent Claim
24 words
A roll as recited in claim 12, said spacer means comprising annular collar means providing expansion chambers to accommodate deformation of said cushioning means.
Claim 15
Dependent Claim
43 words
A roll as recited in claim 13, the axial ends of said annular collar means having annular recesses formed in inner peripheries thereof to receive said cushioning means, said recesses having greater cross-sectional area than said cushioning means and comprising said expansion chambers.
Claim 16
Dependent Claim
64 words
A roll as recited in claim 14, outer peripheries of said axial ends of said collar means surrounding said recesses comprising annular lips for axial engagement with said bearings, said lips being of a length to abut said bearings before said assembly has been compressed sufficiently to reduce the cross-sectional area of said expansion chambers to equal the cross-sectional area of said cushioning means.
Claim 17
Dependent Claim
18 words
A roll as recited in claim 10, said deformable cushioning means having both compressible and substantially incompressible portions.
Claim 18
Dependent Claim
26 words
A roll as recited in claim 10, said cushioning means comprising a plurality of annular rings surrounding said axle and each engaging one of said bearings.
Claim 19
Dependent Claim
22 words
A roll as recited in claim 17, two of said deformable rings abutting each of said bearings adjacent opposite axial ends thereof.
Claim 20
Dependent Claim
22 words
A roll as recited in claim 17, said deformable rings being at least partially interposed radially between said bearings and said axle.
Claim 21
Dependent Claim
38 words
A roll as recited in claim 10, said spacer means comprising annular collar means having axial ends formed with recesses receiving said cushioning means, said axial ends further being formed with lips protruding axially to abut said bearings.
Claim 22
Dependent Claim
32 words
A roll as recited in claim 10, said cushioning means comprising rings radially interposed between said bearings and said axle, axial ends of said spacer means abutting axial ends of said rings.
