ABSTRACT:
In the manufacture of glass fibrous products wherein gaseous streams of fibers are directed through conduits from a generally horizontal direction downwardly in a generally vertical direction towards a moving collection surface, the improvement wherein forming tubes are telescopically associated with downwardly sloping portions of the conduits and supported so that the forming tubes may be positioned at various distances above the collection surface and at various angular orientations relative to the moving collection surface. Also, the shaping of the forming tubes allows additional gaseous streams of fibers to be produced. By selectively manipulating the height and orientation of the forming tubes, the ability to produce a uniform deposition of material onto the moving collection surface is greatly improved. A method and apparatus for the application of binder is also disclosed. Binder atomizing nozzles are located at the periphery of the discharge ports of the individual forming tubes and can be adjusted to be held at any angle desired, thereby producing improved binder distribution onto the glass fibers.
