FILAMENT PRODUCTION LINE Russian patent published in 2025 - IPC B29C48/00 

FIELD: chemistry.

SUBSTANCE: invention relates to processing of polymers, particularly, to extrusion of threads from synthetic stock (carbon-filled polyether ether ketone) with preset characteristics. Line for production of filament is equipped with additional high-temperature drying module installed before drying bin and connected to it. Drying bin is connected to extruder included in the line. Reinforced auger pair with increased heat resistance is installed in the extruder, which is actuated by the engine for the auger rotation. Filament cooling module is two-component, with air-vacuum cooling module and two water cooling baths. Line is equipped with an ionisation module and an additional module for high-temperature air drying of the filament. Ionisation module is installed after the pulling module. Additional module of air high-temperature drying of finished filament is installed after winding module.

EFFECT: high quality of the obtained filament, fewer defects, high strength, removal of electrostatics from the filament, and ionisation of the filament.
