Title:

PATTERNED CLEANING CARD AND METHOD OF MANUFACTURING SAME

Document Type and Number:

WIPO Patent Application WO2005118928

Kind Code:

A3

Abstract:

A cleaning card for cleaning internal surfaces of a machine-actuating mechanism includes a substrate having a central plane between opposed surfaces thereof, a machine direction dimension defined between opposed end edges and a transverse direction dimension defined between opposed side edges. The opposed surfaces each have a plurality of discrete raised areas providing a plurality of transversely extending rows of discrete raised areas. 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 between the opposed surfaces that is greater than the nominal thickness between those surfaces. A method of making a cleaning card includes dampening a substrate of the cleaning card with a fluid, embossing the dampened substrate to provide a plurality of discrete raised areas with elastic memory. Another method of making a cleaning card includes heating a cleaning card substrate during embossing to provide discrete raised areas with elastic memory, either with the substrate dampened or dry.
