A method for producing filaments of polyacrylonitrile and an extrusion head for carrying out said method are provided, wherein the method comprises preparing a polyacrylonitrile polymer solution and passing said solution through an extruder plate that determines the formation of filaments, a central chamber being defined between the extruder plate and a floating plate connected to a vibrating system, said chamber being surrounded by a peripheral chamber into which the polymer solution is introduced under pressure. The polymer solution then passes through to the central chamber via small radial conduits that accelerate the material, and is subjected to vibration in the central chamber before passing through the extruder plate.

A gear box for a reciprocating kneader. A primary rotational gear is attached to a gear box primary shaft and rotates in concert therewith. A secondary rotational gear is engaged with the primary rotation gear and rotates therewith. A secondary shaft is attached to the secondary rotational gear and rotates therewith. A primary oscillation gear is attached to the gear box primary shaft and rotates therewith. A secondary oscillation gear is rotationally engaged with the primary oscillation gear and rotates on the secondary shaft. An eccentric is coupled to the secondary oscillation gear and rotates in concert therewith. A yoke is engaged with the eccentric and oscillates on an axis perpendicular to the secondary shaft in response to the lobe. The gearbox secondary shaft moves along its axis in concert with yoke oscillation. A housing is pivotally attached to the yoke and pivotally attached to a casing at a casing.
