| 摘要 |
A construction of ink dispensing roller (10) is described in which a porous ink metering layer (14) extends around a peripheral surface of a porous ink reservoir (12). To prevent relative movement between the ink metering layer (14) and the ink reservoir (12), the ink metering layer (14) is securely located relative to the ink reservoir (12) by means of elements (15) of the ink metering layer extending beyond each axial end (15) of the ink reservoir and being clamped between end cheeks (17) and the axial end walls (15) of the ink reservoir (12). The ink metering layer (14) is manufactured from sheet material (20) joined by welding along opposite edges (22, 23) into a tubular form. After welding, the tubular form is manipulated so that an inner surface (21) becomes a radially exterior ink dispensing surface (11). <IMAGE> |
