Claim 1
Independent Claim
139 words
A METHOD OF ATTENUATING AND COLLECTING FIBERS FORMED FROM HEAT-SOFTENABLE MINERAL MATERIAL INCLUDING DELIVERING MINERAL MATERIAL INTO A HIGH VELOCITY UNCONFINED GASEOUS BLAST OF A TEMPERATURE ABOVE THE SOFTENING TEMPERATURE OF THE MATERIAL, ATENUATING THE MATERIAL TO FIBERS BY THE VELOCITY OF THE BLAST, PROJECTING THE BLAST AND FIBERS ENTRAINED THEREIN IN A MEDIA PATH PASSING SUBSTANTIALLY THROUGH THE AXIS OF A CYLINDRICAL FORAMINOUS SURFACE, THE FORCE OF THE BLAST BEING SUFFICIENT TO CONVEY THE FIBERS TO THE FORAMINOUS SURFACE, ESTABLISHING A ZONE OF REDUCED PRESSURE ADJACENT THE FORAMINOUS SURFACE FOR CONVEYING THE GASES OF THE BLAST AND THE AIR STREAM INDUCED BY THE VELOCITY OF THE BLAST AWAY FROM THE SURFACE, ROTATING THE SURFACE AT A COMPARATIVELY RAPID RATE, AND CONTINUOUSLY COLLECTING THE FIBERS OUT OF THE BLAST ONTO THE ROTATING SURFACE AT THE ZONE OF REDUCED PRESSURE.
