Cone of elastic thread and method to achieve

Formation of a resilient wire cone which has a good shape and whose unfolding of the elastic yarn from the cone is excellent.Lors winding the elastic yarn on a conical bobbin, the position of a guide transverse carrier (a) is moved so that the ratio (V1 / V2) of the winding speed (V1) at the smaller end surface (b) a cone of said conical coil at the speed of winding (V2) at the larger end surface (c) of a cone of the tapered bobbin and the ratio (L2 / L1) of the linear distance (L2) between the transverse support guide (a) and largest end surface (c) of a cone of the tapered bobbin to the linear distance (L1) between the transverse support guide (a) and the smaller end surface (b) a cone of the tapered bobbin, become presqu'egaux.La mean value of the flow resistance of the elastic yarn unwound from the obtained elastic yarn cone is in the range of 3.2 g to 3.4 g.
