A method and apparatus for forming a fiber mat is disclosed. The attenuation rate of the attenuator or strand advancing apparatus is varied as the attenuator traverses across the mat formation surface such that a constant rate of attenuation of glass filaments from a bushing is realized. This results in more consistent diameter filaments being formed and thus results in the formation of a more uniform mat. The attenuator may also be employed to lay down mat from previously produced forming packages of strand material from any natural or synthetic fiber.


An attenuator for forming a continuous strand mat comprising a constant speed motor at one end of a traversing region, a stationary pulley at the other end of the traversing region, a plurality of wheels over which said strands pass and are attenuated along said traversing region, means for traversing said wheels and means for connecting said motor, pulley and wheels such that the speed of rotation of the wheels is varied with their rate of traversing such that the attenuation of the strands and their associated filaments is constant.
