Abstract
The present invention refers to a process of making a fibrous structure, wherein roughly graded material is provided to rotating, apertured drums. The drums have at least one needle roll in their inside. The roughly graded material is agitated inside the drums, whereby fibers or small fiber clusters are separated from each other. These fibers and small fiber clusters are flung through the apertures to the outside of the drum, where they are directed onto a foraminous carrier to form a fibrous structure. The fibrous structures are especially useful in absorbent articles.
