(a) Schematic diagram of the deposited trace $q(s,t)$ and orbit of the contact point $r(s)$ in the geometrical model. (b) The analytical and experimental results of regular coiling when collector is stationary. The orbit of the contact point $r(s)$ converges to regular coiling whatever the initial values of $r_0$, ${\mathsf{\psi }}_0$ and ${\mathsf{\theta }}_0$ are. (c–f) The orbit of the contact point, the deposited trace and the printed patterns with different $V_{\mathrm{collector}}/V_{\mathrm{fiber}}$. (c–f) The velocity match coefficients $V_{\mathrm{collector}}/V_{\mathrm{fiber}}$ are 0.2, 0.5, 0.65, and 0.8, respectively.
