Three layers of cellulose material unwound from three respective rolls (1, 2, 3) are associated firmly with each other in a continuous process, and the composite sheet (15) thus obtained is wound up again. Each layer has complementary characteristics whereby the final product (15) thus obtained can afford specific usages other than those of the individual layers. More particularly, the two outer layers have a surface-finish granting smoothness and softness to the final product (15), while the inner layer has characteristics of resiliency, mechanical strength, high liquid-absorbency and pre-established elasticity or compressibility performances. For manufacturing the composite product (15), use can be made of cellulose layers of different origins and types, such as paper manufactured by the conventional wet process or paper manufactured by any dry-forming process, or a combination of types of paper produced by different processes. One or more layers may be submitted to any mechanical treatment (7, 8, 9) prior to said association in order to enhance the formation of pervious cells within the final composite sheet (15), whereby to create a "sponge-like" absorbing effect.
