A forming pocket suitable for forming conglomerates from particulate material to be used as an absorbent padding for hygienic products, includes an external forming substrate for receiving particulate material, the substrate having openings and a shape conjugated to a form of the absorbent padding to be made. The forming pocket includes a grid supporting structure, which has openings and is coupleable with the substrate to support the substrate during suction of particulate material through the substrate. The supporting structure has an external surface configured to contact the substrate and has a shape conjugated to the shape of the substrate. A method of making the forming pocket includes obtaining from at least one first metal sheet first and second sets of elements having a plurality of cuts, and wedging the elements of the first set with the elements of the second set via the cuts to make the grid supporting structure.
