Abstract
Method of making an electro-mechanical roll such as a bias transfer roll for use in an electrostatographic apparatus such as a printing or copying apparatus comprising a conductive core having a segmented layer of compressible material positioned in a tandem relation to another thereon to form a generally cylindrical roll.
Claims24
A method of making an electromechanical roll for an electrostatographic apparatus comprising:
- providing a plurality of tubes, each of the tubes having an outside surface and a length and two ends, the tube material comprising at least one of an elastomer and polymer formulation;
- cutting at least one end of each of the plurality of tubes to form a selected end geometry;
- providing an electrically conductive member;
- disposing the plurality of tubes on the electrically conductive member in a tandem relationship;
- and
- positioning the plurality of tubes such that each of the tubes are located up to 0.3 inches apart from another tube.

A method of making an electro-mechanical roll comprising:
- providing a plurality of tubes, each of the tubes having an outside surface, a length of at least 0.5 inches, and two ends;
- cutting an end portion of selected tubes to form selected geometries for matching joining regions between ends of adjacent tubes;
- providing a core member;
- applying an adhesive layer to the core member;
- disposing the plurality of tubes on the core member and matching joining regions between selected geometries of adjacent tubes;
- contacting the joining regions together;
