摘要:
A printing fluid circulating device for use in a printing press having a printing fluid container (32) for containing printing fluid and having a rotatable pickup roller (34) partially submerged in the printing fluid in the container (32). The pickup roller (34) has a surface for picking up printing fluid. The printing fluid circulating device has at least one outer ribbon (10, 12) having a predetermined diameter and a predetermined surface area and at least one inner ribbon (14, 16) also having a predetermined diameter and a predetermined surface area. The diameter of the inner ribbon (14, 16) is less than the diameter of the outer ribbon (10, 12) and the surface area of the outer ribbon (10, 12) is less than the surface area of the inner ribbon (14, 16). Each of the outer and inner ribbons (10, 12, 14, 16) has a substantially helix configuration, the helix configuration of the inner ribbon (14, 16) being opposite the helix configuration of the outer ribbon (10, 12). A rotatable shaft (18) for supporting the outer ribbon (10, 12) and the inner ribbon (14, 16) about a common axis is provided.
