Abstract
Method of filling a silencer with a sound insulating material includes inserting a nozzle into a silencer and feeding sound insulating material, preferably continuous texturized glass, or basalt, or mineral fiber, through the nozzle into the silencer. The nozzle reciprocates linearly and retracts from the silencer while the fibers are being fed into the silencer. The silencer may be rotated while the sound insulating material is fed into the silencer. The nozzle is reciprocated into and out of the silencer and the silencer rotated clockwise or counter-clockwise to control the density and distribution of fill.
