ANORDNING OCH FÖRFARANDE FÖR STYRNING AV GASFLÖDE VID FRAMSTÄLLNING AV MINERALFIBRER SAMT FIBRERINGSARRANGEMANG

摘要

The invention relates to a method and an arrangement for guiding a gas flow in the manufacture of mineral fibres. The arrangement comprises a first support ring, and at least one second support ring, which support rings are placed at a distance from each other around a common imaginary axis. The arrangement further comprises at least one, preferably several, wing member, which is attached at its first attaching point to the first support ring and at its second attaching point to the second support ring. A flexible joint point is arranged between the first and second attaching point. The arrangement also includes means for moving the first or second support ring around the common axis. The invention also relates to a fiberising apparatus comprising the arrangement.
