Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
139 words
A METHOD OF PRODUCING AND PACKAGING CONTINUOUS GLASS FIBER STRAND OF UNIFORM DIAMETER WHICH COMPRISES ATTENUATING GLASS FIBERS FROM A SUPPLY OF MOLTEN GLASS, APPLYING A SUBSTANTIALLY CONSTANT FORCE TO SAID FIBERS AT A FIRST POSITION SPACED FROM THE REGION OF FIBER WITHDRAWL TO WITHDRAWN THE FIBERS AT A SUBSTANTIALLY CONSTANT LINEAR RATE OF SPEED, THEREAFTER AT A SECOND POSITION SPACED FROM THE FIRST POSITION AND THE REGION OF FIBER WITHDRAWL APPLYING ANOTHER FORCE TO SAID FIBERS OF LESS MAGNITUDE THAN THE WITHDRAWAL FORCES, EXERTING A TENSION ON THE FIBERS THROUGHOUT THE LENGTH THEREOF BETWEEN THE FIRST AND SECOND POSITIONS, SAID TENSION BEING LESS THAN THAT EXERTED BETWEEN THE GLASS SUPPLY AND THE FIRST POSITION BY THE APPLICATION OF THE WITHDRAWAL FORCE, AND LAYING SAID FIBERS IN A PLURALITY OF LAYERS ON A ROATING SURFACE AT SAID SECOND POSITION.
Claim 2
Independent Claim
