Features of the unwinding of thin filaments of chemical fibers from cylindrical bobbins of small diameter

This article examines certain aspects of the unwinding of thin filaments of chemical fibers from small-diameter bobbins. The aspects discussed are related either to the penetration of turns in lower-lying layers of the winding by turns in higher layers or to the “sticking” of turns (if the filament...

Summary:This article examines certain aspects of the unwinding of thin filaments of chemical fibers from small-diameter bobbins. The aspects discussed are related either to the penetration of turns in lower-lying layers of the winding by turns in higher layers or to the “sticking” of turns (if the filament is coated) deep in the winding. Both of these phenomena lead to rupture of the filament as it is being unwound from the bobbin. A method is described for calculating the optimum parameters of a flanged cylindrical bobbin in order to prevent filament rupture due to penetration and sticking of the turns. The optimum parameters that are calculated are for filaments of specified lengths.
