Abstract
Mechanically entangled, in-line formed, packs of glass fibers are mechanically entangled differently at different portions of the web. In one exemplary embodiment, in-line formed glass fibers are mechanically entangled by any combination of two or more entangling devices. The two or more entangling devices may be the same or different. In one exemplary embodiment, the glass fibers are mechanically entangled from at least a first side of a web by a first entangling device and are mechanically entangled from a second side of the web by a second entangling device.
