  • Abrasive shim compliant doctor blade
    Patent number: 5797076
    Abstract: A compliant doctor blade has a metal bar (13) with bottom attached by dual side adhesive tape (15) to a resilient layer of porous foam (7). The bottom of the foam layer is attached by dual side adhesive tape (8) to a shim (1), which is stiff in the direction of movement of the roller (9) which the shim contacts. The shim has a polyester body (3) and a bottom layer (5) containing abrasive grit and conductive carbon black. Finally, the end of the doctor blade is dipped in a conductive paste which hardens into a conductive coating (17) which bridges the conductive layer of the shim and the metal bar. Advantages are reduced costs and improved performance, particularly with respect to streaks from prenip packing.
