ABSTRACT:
An interposer device for an impact band line printer comprises a spring steel interposer plate member with plural chevron flexure elements etched therein so that the apexes thereof are arranged in a row across the plate. A polymer striker strip has a series of cutouts configured in a herringbone pattern and forms a longitudinal spine section with support ribs connecting the spine section to the margins of the strip. Two sided pressure adhesive tapes attached along the margins of the strip are bonded to the surface of the interposer plate with the spine section aligned with but unattached with the apexes of the chevron elements. A laminated interposer strip assembly comprises a polymer striker strip layer with adhesive attachment layers on one side along the margins and a backing layer removably attached to the other side of the striker strip layer.
