Patent ID: 7833377

Claim:
A process for preparing an animal incontinence device, comprising the steps of: providing a base layer of tissue; applying a uniform layer of superabsorbent polymer particles to a major surface of the base layer of tissue; applying water to the base layer of tissue having the uniform layer of superabsorbent polymer particles thereon; applying a cover layer of tissue over the base layer of tissue having the uniform layer of superabsorbent polymer particles thereon, to form an absorbent layer assembly; passing the absorbent layer assembly between a heated nip roll and a laminating roll covered with a material softer than a material of the heated nip roll after applying the water to the base layer of tissue, wherein the material covering the laminating roll is paper, the heated nip roll and the laminating roll applying a pressure to the absorbent layer assembly without crushing the superabsorbent polymer particles, to at least partially adhere together the cover layer of tissue, the uniform layer of superabsorbent polymer particles, and the base layer of tissue, to form an absorbent layer; inserting the absorbent layer intermediate a base layer of liquid-impervious polymer film and a top layer of porous, hydrophilic, woven or non-woven polymer fibers, to form an animal incontinence device assembly; and laminating together at least a portion of the animal incontinence device assembly to form the animal incontinence device.
