ABSTRACT:
A nonwoven uniform web is formed from particulate material and a binding agent in a moving conveyor belt. The material is fed to the belt through a cowl in a random fashion and air is removed from the material; the layer of material is subsequently thinned by a peak removal device and is precalendered, rolled and then heated to activate the binding agent. The resulting web has similar mechanical properties in length direction and width direction, and has a high elastic recovery.
