Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
206 words
THE METHOD OF FORMING A SHEET COMPOSED OF MULTIPLE LAYERS OF FIBERS COMPRISING THE STEPS OF RECIPROCATING A FURNACE CONTAINING MOLTEN FIBER-FORMING MATERIAL AXIALLY ALONG AND OVER A ROTATING DRUM, DISCHARGING THE MOLTEN MATERIAL THROUGH ORIFICES IN THE FURNACE AND ALLENUATING THE MOLTEN MATERIAL INTO FIBRES, COLLECTING THE FIBERS ON THE DRUM AS THE FURNACE IS MOVED AXIALLY OF THE DRUM, MOVING THE FURNACE THROUGH A CYCLE IN WHICH THE FURNACE IS MOVED THROUGH A FIRST SET OF ONE OR MORE TRAVERSES SUBSTANTIALLY FROM ONE TO THE OTHER END OF THE DRUM AT A FIRST CONSTANT SPEED TO LAY FIBERS ON THE DRUM AT A DESIRED ANGLE OF LAY AND THEN THROUGH ANOTHER SET OF ONE OR MORE TRAVERSES SUBSTANTIALLY FROM ONE TO THE OTHER END OF THE DRUM AT ANOTHER CONSTANT SPEED TO LAY FIBERS AT A DIFFERENT ANGELE OF LAY THAN THE PRECEDING SET, APPLYING A BINDER TO SAID FIBERS, REPEATING SAID CYCLES TO BUILD UP A COLLECTED CONDENSED MAT OF FIBERS SO LAID ON THE DRUM TO A DESIRED THICKNESS, SLITTING THE MAT SO FORMED AXIALLY OF THE DRUM AND REMOVING IT AS A SHEET, AND EXPANDING THE SHEET BY PULLING IT AT SUBSTANTIALLY A RIGHT ANGLE TO THE LAY OF THE FIBERS.
