Abstract
Disclosed are an improved apparatus for collecting fine fibers, such as glass fibers, having a mean diameter of less than two microns from a gaseous stream, a method of collecting fine fibers using the apparatus and the novel new product produced by this method. The improvement lies mainly in the way in which the collection drum is supported and sealed which allows the collection to take place at relatively high partial vacuums. The fiber is also consolidated in the gaseous stream by passing it through a duct having at least one approximately ninety degree turn therein.
