A sanding pad comprises a laminate structure of a deformable and flexible core layer defining a first surface and an opposing second surface, each said surface having a sandpaper layer affixed thereto, whereby each said sandpaper layer is bonded to a plurality of fabric features, such as pile loops defining a respective one of the first and second core surfaces, whereby the pile loops defining the first core surface can flex in an opposite direction from the pile loops defining the second core surface when the core layer is deformed and flexed. In this regard, the core layer can flex in a variety of directions and conform to a variety of shapes and geometries, including convex and concave contours. The sandpaper layers each comprise an abrasive grit mounted to a backing layer which is bonded to the pile loops of the core layer.

A method for producing endless abrasive articles (100) includes providing a mandrel coil (200), which comprises a first complete turn (B0.sub.A) formed of an endless mandrel belt (B0), feeding the endless mandrel belt (B0) to an input end (IN0) of the mandrel coil (200) and unwinding the mandrel belt (B0) from an output end (OUT0) of the mandrel coil (200) so as to move the surface of the first complete turn (B0.sub.A) of the mandrel coil (200), forming a laminated sleeve (SLEEVE1) by feeding a first strip (S1) on the moving surface of the first complete turn (B0.sub.A) of the mandrel coil (200), and forming an endless abrasive article (100) by cutting the laminated sleeve (SLEEVE1).

A grinding tool (1) has a replaceable abrasive (4). A grinding layer (9) of the abrasive (4) faces a drive shaft (2) of the grinding tool (1). This enables a grinding of a workpiece (W) while exerting a tensile force (F). Surface areas (O) of the workpiece (W) facing away from a processor may thus be processed easily and flexibly.
