ABSTRACT:
A yarn winder for winding a yarn about a spherical body includes a pair of cylindrical rollers extending in parallel with each other in a horizontal plane and rotatively driven in the same directions and reciprocatively driven in respective axial directions opposite to each other, and a two-frustoconical roller extending in parallel with the cylindrical rollers and urged by a predetermined force against the spherical body. The two-frustoconical roller includes a center roller having a yarn guide and two taper rollers in the form of two frustocones separated from the center roller and rotatably arranged on both sides of the center roller so that smaller diameter ends of the frustocones are facing to the center roller. In operation, the time for reciprocative movement of the cylindrical rollers is so controlled that an oscillating angle of the spherical body becomes equal to a rotating angle of the spherical body.
