A pinch clamp and mount are provided. The pinch clamp includes a first member and second member including rounded pinch surfaces. The second member is pivotably coupled to the first member at a first end. A threaded shaft is pivotably coupled to a second end of the first member. A second end of the second member includes a seat configured to receive the threaded shaft and a nut thereon. The seat includes protrusions at the second end that prevent the nut from sliding out of the seat. The mount includes a body having a flat bottom surface. An internal wall defines a through hole in the flat bottom surface. Two guide rails on a top surface of the body define a central slot configured to receive the clamp. A pair of keyed slots within the two guide rails are configured to receive a pair of keyed projections on the clamp.

In order to facilitate the removal of ink and other material commonly used in flexography and rotogravure processes, an automated apparatus and method for cleaning a printing cylinder in a tank is disclosed. The tank is adapted to receive a printing cylinder that is to be cleaned of a dried ink on a surface thereof and a cleaning solution in an amount sufficient to substantially immerse the printing cylinder. It also includes a sprayer within the tank for spraying the surface of the printing cylinder with the cleaning solution and wheels within the tank for rotating the printing cylinder as the sprayer is spraying the surface thereof. The method includes the steps of providing a tank for receiving a printing cylinder that is to be cleaned and substantially immersing the printing cylinder in a cleaning solution within the tank. It also includes spraying a surface of the printing cylinder with the cleaning solution in the tank and rotating the printing cylinder as the surface of the printing cylinder is being sprayed. In addition to the foregoing, the automated cleaning may be facilitated by heating the cleaning solution, filtering the cleaning solution as it is cycled from a reservoir to the tank, and rinsing residue from the printing cylinder.
