In a method of producing a non-woven mineral fiber web, mineral fibers are produced from a mineral material by means of a mineral fiber generating means. The mineral fibers are transferred from the mineral fiber generating means by means of a carrier air stream, and droplets and/or particles of a bonding agent or coupling agent is introduced into the carrier air stream for causing the mineral fibers to be bonded or linked together. In order to eliminate waste of bonding agent or coupling agent material, the droplets and/or particles predominantly have diameters larger than a minimum diameter corresponding to a droplet and/or particle showing substantially no tendency to impact the mineral fibers of the carrier air stream. |
