ABSTRACT:
A machine-actuating mechanism cleaning card includes a substrate having a central plane between opposed surfaces, a machine direction dimension between opposed end edges and a transverse direction dimension between opposed side edges. The opposed surfaces each have a plurality of discrete raised areas arranged in transversely extending rows. At least some of the discrete raised areas in at least some of the transversely extending rows extend outwardly on each side of the central plane. The discrete raised areas each include a peak and a peripheral wall joined at one edge to the peak and having an opposed edge that is closer to the central plane than the peak. The cleaning substrate has an effective thickness that is greater than the nominal thickness. Methods of making cleaning cards also are part of the invention.
