Abstract
A process and apparatus for compacting a web (12) which contains a superabsorbent material (32) can include a plasticizing of the superabsorbent material contained in the web (12), and a compressing of the web (12) at a relatively low pressure. The selected, low pressure can be arranged to substantially avoid an excessive fracturing of the superabsorbent material.
