The invention concerns a composite ferrule adapted in particular for being mounted on a metal carrier cylinder and used for transferring ink, comprising a base ferrule (10) capable of radial deformation, a layer (12) with limited deformability, an intermediate layer (14) for absorbing radial deformation, and a ceramized layer (16) made of a material with high capacity for dissipating heat. The ceramic coating (18) is etched, generally laser etched, so as to give to the external surface of the ferrule capacity for retaining ink for use as anilox in a printing machine.
La présente invention concerne un manchon composite adapté notamment pour être monté sur un cylindre porteur métallique et utilisé pour le transfert d'encre, comprenant un manchon (10) de base déformable radialement, une couche (12) à déformabilité limitée, une couche (14) intermédiaire d'absorption des déformations radiales, et une couche (16) de matériau à forte capacité de dissipation de la chaleur, céramisée. Le revêtement (18) céramique est gravé, généralement au laser, en sorte de donner à la surface externe du manchon des capacités de rétention d'encre pour permettre son utilisation comme anilox dans une machine d'impression.
