<p><P>PROBLEM TO BE SOLVED: To provide a method and material for making a brush or pad for removing materials, particles, or chemicals from a substrate. <P>SOLUTION: The brush or pad includes a rotatable base for supporting a porous pad material. The base includes an inner surface and an outer surface, and a plurality of channels in the base for interlocking the porous pad material with the base. The porous pad material covers at least a portion of the outer surface of the base and is used for removing materials from various substrates. The porous pad material fills one or more of the channels in the base and interlocks the porous pad material with the base. Preferably the channels fluidly connect the inner surface with the outer surface of the base and aid in the alignment of porous pad nodes and the distribution of fluid within the porous pad. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
