Method of making a porous roll assembly.

摘要

The present invention provides a porous roll assembly which comprises a core shaft (2) and a porous roll body (1) fitted on the shaft. The roll body include a stack of axially compressed porous disks. According to the method of the invention, the stack of porous disk is ccmpressed divisionally and successively, so that all of tha disks are evenly compressed even if the roll body is relatively long. The resulting roll body is substantially uniform in Shore hardness and porosity over the entire length of the roll body.
