PRODUCTION LINE OF FIBRE (REINFORCEMENT ELEMENTS) FROM POLYMER MASS Russian patent published in 2014 - IPC E04C5/07 D01D5/98 

FIELD: construction.

SUBSTANCE: production line of fibre from polymer mass in the process direction includes an extruder, an extrusion head for formation of a thread from polymer mass, which has a cross section of the specified shape, a thread cooling bath with cooling liquid, a withdrawal-roll set containing at least one upper roll and one lower roll with S-shaped threading, a thermal plastification chamber, the main tension set containing at least one upper roll and one lower roll with S-shaped threading between them, main thread drawing zone, a corrugating device and a cutting mechanism for thread cutting into equal pieces - fibre. The line includes an additional tension set containing at least one upper roll and one lower roll with S-shaped threading between them, which is installed after the main tension set, an additional thread drawing zone formed between the main tension set and the additional tension set, heaters for heating of the withdrawal-roll set, heaters for heating of the thermal plastification chamber, heaters for heating of the main tension set, as well as fans with outlet nozzles for removal of residual moisture from thread, which are installed in a zone between the withdrawal-roll set and the thermal plastification chamber.

EFFECT: improving strength and quality of produced fibre.
