    Abstract: A method and apparatus for manufacturing an embossed sanding sponge includes a first roller, a press base, and a conveyor. The first roller is mounted about an axis and configured to be rotatably driven about the axis. The first roller also includes a circumferential surface having a predetermined channel pattern. The press base is positioned proximate to the first roller and configured to compress the sponge material against the first roller. The conveyor has a support surface configured to translate and support the sponge material. In use, the circumferential surface of the roller engages the sponge material. The roller and the sponge material respectively rotate and translate in order to continuously press the predetermined channel pattern against the sponge material for manufacturing the embossed sanding sponge.
