FIELD: non-woven materials; technological processes.
SUBSTANCE: provided is spinneret for forming of elementary threads, and also cooling device for cooling of elementary threads. In the area of the spinneret there is at least one device for suction of monomers for suction of gases formed during the forming process. Monomer suction device comprises at least two areas of suction orifice of CD direction arranged alternately in machine direction, respectively, passing transversely to machine direction and opposite to molding field. Both areas of CD direction suction hole are adjusted so that suction of larger volumetric flow of gas can be performed through one of both areas of CD direction suction hole than through other opposite area of CD direction suction hole.
EFFECT: device for production of spunbonded non-woven materials from endless filaments.
