response to the signal application_number US 10730179 A description as shown in fig1 molten mineral material such as molten glass 10 is delivered to rotating spinner 12 which fiberizes the glass by centrifugal force the glass fibers can be maintained in a plastic attenuable state by annular burner 14 the glass fibers can be turned down into a flow of fibers such as cylindrical veil 16 by annular blower 18 the veil collects as insulation pack 20 on collecting surface 22 which can be a continuous foraminous conveyor belt nozzles 24 are activated periodically to intermittently direct gases into the flow of mineral fibers to uniformly distribute the veil or flow of fibers across the width of the collecting surface the nozzles can be supplied with air steam or other gases via supply conduits 26 which can receive the supply of gases from a source not shown the supply conduits can be adapted with accumulators 28 to dampen the effect of the pulsation of the gases from the source of the gases valves 30 are operated to intermittently interrupt and then reestablish the supply of gases from the source going into the nozzles as shown in fig2 the nozzles can be arranged so that a pair of opposed nozzles is adapted to act upon each veil of a multi veil fiber forming and fiber distribution system the dashed arrows indicate the direction of flow of gases from the nozzles the conveyor can be driven by drive roll 34 which can be powered by any suitable means such a motor not shown the conveyor.
