Abstract

The invention relates to a process for producing a perforated roller shell for a suction roller of a papermaking machine, in which the shell material is realized by lamination or by winding around a mould 12 having pins 13 which are removed once the shell material has hardened and/or once it has been applied, whereupon holes 15 are left in the shell. The invention also relates to a roller which is made by use of the process. The invention additionally relates to a member for producing a perforated roller shell 11 of a suction roller 10, which member comprises a mould 12 having protruding pins 13, around which mould the shell material is wound or laminated. <IMAGE>
