Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
123 words
Apparatus for attenuating filaments from streams of molten material comprising: feeder means having a plurality of orifices adapted to supply a plurality of streams of molten material; a plurality of elements in spaced apart relationship adapted for the passage of a fluid therethrough to attenuate said streams into filaments along a path of advancement; first means for moving the elements to vary the space between the elements; second means for moving the elements in a direction substantially transverse to the path of said filaments being attenuated, the second means being connected to the first means; and third means for moving the elements in a direction substantially along the path of the filaments being attenuated, the third means being connected to the second means.
