Figure 4
Parametric study of the winding dynamics. Angular velocity ω s of the string and helical angle θ t of the threads are plotted with \(\bar{x}\) for different initial conditions \({\omega }_{{\rm{s}}}(x,0)={\omega }_{{\rm{dm}}}{x}^{m}/{l}_{{\rm{s}}}^{m}\), where m = 1 in (a) and (b), and m = 1/2 in (c) and (d). Temporal evolution of the winding angle φ t of the threads is shown in the inserts of (a) and (c).
