FIELD: technological processes.
SUBSTANCE: invention is related to device and method for manufacturing of film or fiber from reduced amount of polymer material. Invention is related to system of batch-off roll in device. Device comprises facility for melting and shaping of material composition in mold, facility for cooling of melted and molded material, facility for drawing of film or fiber, including the first and second drawing rolls. Device comprises facility for control of torsion torque in process of drawing to the minimum value of 1.5·10-3 Nm, in which rotation speed of every drawing roll with diametre from 35 to 100 mm may be established from 0.25 to 35 rpm. Speed of rotation is controlled by microstep method.
EFFECT: provision of possibility to use small-sized equipment, and also to use reduced amount of polymer material.
