Abstract
Innovation suggests methods and installations for productions of viscose filament rayon with cyclically varying linear density. According to the method of the invention, constantly synchronizated viscose solution supplying and spinning devices actuation is interrupted, as first (27) and second (28) spinning devices and arranging freshly spun yam in centrifuge system 39-5 are actuated by the use of existing power feeding installation (40-4), motors 40-1 and 40-2 and reduction gear groups 39-1 and 39-2 named as the first power feeding and actuating installation. According to the method of the invention new power feeding 40-7 and actuating; 40-3 installation is added to the same spinning machine named second power feeding and actuating installation which work runs under unit 42 control. According to the invention power shaft 21 actuation do not depends on other spinning devices actuation anymore and quantity of viscose dozed to the spinning could be changed independently of other devices work.
