Abstract
Abstract A method of forming a coated roll having a body and an outer layer of coating material which comprises positioning a tubular sleeve of release material, having on its inner surface a layer of coating material, in surrounding relationship with the body, compressing the layer of coating material to bond the layer to the outer surface of the body and subsequently removing the tubular sleeve.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
78 words
A method in accordance with claim 1 wherein said body includes a core and include the steps of introducing an elastomeric material between said core and said surrounding coated tubular sleeve and restraining said tubular sleeve from radially outward movement during said introducing step, and wherein said relative movement effecting step comprises forcing said introduced elastomeric material against said layer of coating material on said sleeve to bond said coating material layer to the underlying introduced elastomeric material.
Claim 2
Dependent Claim
15 words
A method in accordance with claim 1 wherein said tubular sleeve is formed of polytetrafluoroethylene.
Claim 3
Dependent Claim
17 words
A method in accordance with claim 2 wherein said layer of coating material comprises an elastomeric material.
Claim 4
Dependent Claim
61 words
A method in accordance with claim 1 wherein said roller comprises a rigid material and wherein said tubular sleeve is formed of polytetrafluoroethylene and including the step of heat shrinking said coated tubular sleeve into bonding engagement with the outer surface of said roller to compress said coating material layer and bond said layer to the outer surface of said roller.
