An adapter sleeve (301) comprising at least two rigid load-bearing end radial spacer members (112d,112e), each defining an inner flange (212), an outer support surface (213b) and a radially extending web (214) rigidly connecting said inner flange (212) to said outer support surface (213b), each said inner flange extending axially and defining an inner annular surface (212a) and an outer annular surface (212B);
an inner layer (104) extending axially between first and second end radial spacer members and having a first end (105a) connected to said inner flange of said first end radial spacer member;
an external layer (110) extending axially between said first and second end radial spacer members and having first and second ends connected respectively to said outer support surface of said first and second end radial spacer members, said external layer being configured and composed with a rigid outer surface for supporting the printing cylinder, said external layer being radially spaced apart from said inner layer (104) and defining an empty space (130) therebetween. |
