Abstract
Provided is a process and apparatus for applying a liquid binder to fibers. The process involves introducing heat curable liquid binder onto moving fibers by atomizing the liquid binder and applying the atomized binder from a point within the moving column of fibers. Better binder efficiency and a more efficient overall process is realized.
Claims14
A process for applying liquid binder to fiberglass, comprising the steps of:
- beating glass to liquify same;
- introducing the liquified glass into a spinning rotor having a sidewall containing openings therein whereby the molten glass is extruded through the openings by centrifugal force to form primary fiberglass fibers;
- attenuating the primary fibers to create a circular column of moving fibers;
- and
- expelling liquid binder from a rotating rotary member within the column into an atomizing screen that atomizes the liquid binder, wherein atomized binder is introduced to the moving fibers.

A process for producing a fibrous body, comprising the steps of:
- heating material capable of being fiberized to liquify same;
- introducing the liquified material into a spinning rotor having a sidewall containing openings therein whereby the liquified material is extruded through the openings by centrifugal force to form primary fibers;
- attenuating the primary fibers to thereby create a circular column of moving primary fibers;
- expelling liquid binder from a rotating rotary member within the column into an atomizing screen that atomizes the liquid binder, wherein atomized binder is introduced to the moving fibers;
- collecting a layer of the fibers and atomized binder;
- and
- heating the layer of fibers and atomized binder to cure the atomized binder.
