  • Patent number: 4756679
    Abstract: A nozzle plate having a plurality of passages is adapted to permit a melt to flow therethrough to form a stream of filaments. A dispersing head is located downstream of the plate and in the filament stream. The head is substantially in the form of a cylinder with its axis substantially parallel to the stream. An inlet for coolant (preferably air) connects a source thereof with the head. The wall of the head is porous, thereby permitting the coolant to pass through the wall and impinge on the filaments.
