Abstract

In a method of making high-absorbency articles for use in wound care, incontinence, ostomy applications, and other more varied uses, a loose high-absorbency powder is arranged between a pair of sheets. The sheets and powder are compressed in certain areas. Loose powder is extracted e.g. by vacuum or gravity, and by cutting and sealing, packet-like articles are produced.
