    摘要： Apparatus having unwinding and winding reels (25, 26) for a cleaning cloth (P), which when passing between the two reels is set under longitudinal tension on a roller or other linear counteracting means (24) against which this cloth is made to rub in reverse direction on the surface to be cleaned of the cliché plate (2) of the printing cylinder (1) of a flexographic machine. Said roller or other linear counteractingacting means (24) has a rigid surface contacting the cloth (P) and facing the printing cylinder (1, 2) and in that the displacement means of the carriage, that supports the cloth cleaning device, to move this device towards and then away from this printing cylinder (1, 2), are means suitable to produce an accurate movement, so that during the cliché plate (2) cleaning step the cloth, set on this roller or other linear counteractingacting means (24), touches with its outer surface the exposed surface (S) of the cliché plate (2), the interference with this surface (S) being minimum. In the active step of cleaning the cliché plate (2) of the printing cylinder, the means that provide for the unwinding of the cloth (P) under tension cause the cloth to move forward with small continuous or intermittent movements.

    摘要： The invention relates to an apparatus for cleaning the surfaces of impression cylinders with the aid of a cleaning cloth which is transported from a supply roller over a pressure strip to a collecting shaft for dirty cleaning cloth, having an adjusting device for advancing and withdrawing the pressure strip in relation to the impression cylinder, a drive which lies behind the pressure strip being provided for the advance of said adjusting device. The pressure strip is guided within a bar profile of substantially U-shaped cross section, in which a groove-shaped pressure chamber (14) is situated at the base of the U-profile, which groove-shaped pressure chamber (14) extends over the length of the bar profile and out of which an elongate drive element (16, 30) can be advanced against the pressure strip by the introduction of a pressure medium into the pressure chamber.

    摘要： A bladder (218) for bringing and engaging a cleaning cloth (105) into contact with a blanket cylinder (100). The bladder (218) has a molded (extruded or machined) shape optimized to, when inflated, provide a contact surface (500) elevated above the remainder of the bladder (218). When the bladder (218) is not inflated, the contact surface (500) or central portion remains elevated above the reminder. In addition, the device has improved contact characteristics, providing significant improvement in the consistency of contact surface with less sensitivity to pressure fluctuations between the cylinder (100) and the bladder (218) over prior art.
