VERFAHREN ZUR HERSTELLUNG EINER MEHRSCHICHTIGEN SAUGFÄHIGEN STRUKTUR

摘要

The present invention utilizes the smooth continuous motion of a masking belt to concentrate air-entrained absorbent materials on the surface of a moving fibrous substrate. Air flowing through the open areas of the masking belt carries the entrained material into the fibrous web. The fibrous web acts as a filter to separate the entrained material from the air stream. Substantially all dispensed material is captured by the fibrous web, and expensive and complex absorbent material recycle systems can be eliminated.
