Abstract
A method and apparatus for dry forming a paper, or other nonwoven web, from fibers or fiber flocs. The flocs or bundles are exposed to an oscillating electrostatic field, the resultant mechanical agitation shakes individual fibers loose, which then fall through a screening wire onto a moving forming wire. At a station downstream from the forming section a binder is applied. After appropriate conditioning, the newly formed web is picked off for further processing.
