A press ring structure is described adapted to be mounted upon a press consolidator axle assembly of the type comprising a central axle formation and a plurality of a plurality of elongate mounting formations extending outwardly from a surface of the central axle and an assembleable and dissassembleable press consolidator is described having a plurality of such press ring structures and a roller assembly comprising a central axle and a plurality of such ring mounting systems. The press ring structure comprises a plurality of annular segments, each annular segment having a first end and a second end each adapted to be co-operably mutually mechanically engageable with an adjacent end of a further segment in that each end portion comprises a flanged engagement portion, the respective flanged engagement portions of the ends of a pair of segments to be engaged adjacently being configured to seat one above the other when so engaged and further configured co-operably to define a through channel to receive a releasably engageable fixing formation whereby a first end of a first segment and a second end of an adjacent segment are thus adapted to be mechanically mountable together upon an elongate mounting formation in such manner as thereby additionally to be joined to each other so as to constitute when each annular segment is so engaged and mounted a complete and contiguous annular press ring structure.La présente invention concerne une structure danneau de pression apte à être montée sur un ensemble daxe de consolidation à pression du type comprenant une formation daxe central et une pluralité dune pluralité de formations de montage allongées sétendant vers lextérieur à partir dune surface de laxe central et concerne également un système de consolidation à pression montable et démontable doté dune pluralité de structures danneau de pression de ce type ainsi quun ensemble de rouleau comprenant un axe central et une pluralité de systèmes de montage danneau de ce type.
