Abstract
Abstract Method of making a composite roll including a central metal shaft having a plurality of porous discs assembled thereon and held in compression. A sleeve member of synthetic plastic material is received over the porous discs. The porous discs are machined to form a substantially smooth and undamaged cylindrical surface prior to application of the plastic sleeve thereover.
