    Abstract: A method and apparatus (1) for making a cohesive sheet from particulate substantially water insoluble, absorbent hydrogel-forming polymer materials. The method comprises the steps of continuously layering dry absorbent gelling particles onto a conveyor. The particles are then sprayed with a liquid mixture, which is a solution of water and a cross-linking agent for the polymers in the particulate material. The amount sprayed is sufficient to cause effective surface cross-linking of the particulate material after the sheet is cured. The layering and spraying steps can then be repeated a number of times if desired. Pressure is then applied to the particulate material by passing it through a pair of compaction rolls. The apparatus (1) comprises a conveyor (3), one or more feeders (5) for layering the dry absorbent gelling particles onto the conveyor, one or more sprayers (4) for spraying the particles on the conveyor with the liquid mixture and a pair of compaction rolls (6).
