Abstract
The roller comprises a core (56) having an elastomeric covering which comprises an outer exposed region (60) and an intermediate region (58) positioned between the outer region (60) and the core (56). The outer region (60) has a thickness which decreases towards each end of the roller and the intermediate region (58) has a thickness which increases towards each end of the roller. When associated with another such roller to form a nip in an apparatus for wet processing sheet materials, carry-over is reduced, leakage when no sheet material is passing through the nip is reduced, and the risk of physical damage to the sheet material is reduced.
