Abstract

A cleaning card for use in cleaning internal surfaces of machine components includes a substrate having a central plane between opposed outer surfaces, a machine direction dimension defined between opposed end edges and a transverse direction dimension defined between opposed side edges. The opposed surfaces have a plurality of discrete raised working areas for engaging and cleaning internal surfaces of the machine components. The working areas each include a peak and a peripheral wall having an edge remote from the peak and the peak of each raised working area is further from the central plane than the edge of the peripheral wall remote from the peak. The cleaning card substrate has an effective working thickness that is greater than the nominal thickness between the opposed surfaces. The substrate also has a plurality of raised, rigidifying areas that extend continuously over a majority of the machine direction dimension of the cleaning card and at least one of the rigidifying areas extends outwardly on each side of the central plane of the substrate.
