- Abstract
Autefa Automation GmbH has developed a lapper system called WebMax which eliminates the effect of heavy web edges that is a common problem in cross lapped nonwovens. A discussion of the cross lapper technology is provided by the author to explain the so-called smile effect during nonwoven production. Results of a test provide information on what exactly happens during the bonding process and why some methods fail to eliminate the heavy edges in the final product. With the WebMax system, a corresponding weight profile is made available during the laydown in the cross lapper. It influences the bonding process in a way that ensures even weight distribution over the entire product width. In summary, the WebMax system is a proven method for eliminating weight unevenness on carded web installations. Consequently, the system offers a very short return of investment.
