FIELD: textiles and paper.
SUBSTANCE: device (6) for a plant for forming fibrous mats which fibers are formed of a material suitable for extension by method of internal centrifugation using a gas stream, comprises a guide channel for directing fibers having a longitudinal axis (X), as well as the first part (61) which forms the channel input through which the fibers are introduced into the channel, the second part, or the central part (62), and the third part (63) forming a channel output. The device also comprises hinged means made with the ability of mechanical impact on the third part (63) of the channel providing a change in its size and/or location of the at least one of its parts, relating to the said longitudinal axis (X).
EFFECT: provision of opportunity to obtain uniform mats with desired surface density, insulating property or insulating effect.
