Abstract
An apparatus and method for increasing the heating efficiency of a nonwoven web using heated air are provided. A flow modifier including a turbulence inducing bar arrangement is positioned between the heated air supply and the nonwoven web. The flow modifier increases the turbulence of the heated air before it contacts the nonwoven web, resulting in more thorough penetration of the web by the air, and better convective heat transfer between the heated air and the nonwoven web.
