Abstract
Abstract In a methodof manufacturing a vibration damper of the kind comprising spaced apart inner and outer rings coupled together by an intermediate ring of elastomeric material, the latter is moulded with inner and outer peripheral surfaces having a textured finish, e.g. V-section ribs, which allow the elastomeric ring to be assembled between the other two rings with less tendency for jamming and run-out to occur.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
55 words
A method of manufacturing a vibration damper of the kind referred to wherein the elastomeric ring is produced as a moulding and is substantially inserted between the inner and outer rings, characterised in that the elastomeric ring is moulded in such a way that at least one of its peripheral surfaces has a textured finish.
Claim 2
Independent Claim
55 words
A method of manufacturing a vibration damper of the kind referred to wherein the elastomeric ring is produced as a moulding and is substantially inserted between the inner and outer rings, characterised in that the elastomeric ring is moulded in such a way that at least one of its peripheral surfaces has a textured finish.
Claim 3
Dependent Claim
58 words
A method as claimed in Claim 1 characterised in that the elastomeric ring is moulded with a plurality of closely spaced protuberances on said at least one peripheral surface which protuberances have some freedom to deflect about their roots in the axial direction, i.e. the direction of insertion of the elastomeric ring between the inner and outer rings.
Claim 4
Dependent Claim
14 words
A method as claimed in Claim 2 characterised in that said protuberances comprise ribs.
Claim 5
Dependent Claim
22 words
A method as claimed in Claim 3 characterised in that said ribs are of V-section and extend circumferentially of said elastomeric ring.
