| 摘要 |
The present invention relates to a process and an arrangement for improving a process for the manufacture of mineral fibres, in which the fibre is drawn from the periphery of a rotary centrifuge 2 by means of hot combustion gases and in which, additionally, bonding agent 3,7 is injected and/or cooling secondary air is mixed into the fibre mass flow formed by drawn fibres, hot air and combustion gases. According to the invention, after the fibre has been drawn, air and combustion gases are removed from the fibre mass flow, preferably by suction, and at the same time the fibre mass flow is preferably expanded from the original. <IMAGE>
