<p>A roller having an improved covering layer and a process for making such. The covering layer has a generally continuous, seamless matrix phase and a generally circumferentially extending open-celled foam structure which is distributed throughout such matrix phase and preferably is coextensive therewith. The process involves the steps of mounting an open-celled, preformed foam layer over roll circumferential portions, depositing a liquid comprising a resin or resin precursor in the foam layer, and converting such liquid into a solid organic resin.</p> |
