Abstract
A device for winding threads on a spool, comprises a spool spindle, a guiding roller, and a changing unit including two rotors driven in opposite direction and each provided with at least two propeller-like wings, the rotors having axes located with a small distance parallel near one another, the rotors being rotatable in rotary planes in which the wings of the rotors rotate and which are spaced from one another by a small distance d, the changing unit being formed so that a thread running at end points of the changing region forms with the rotary planes an acute angle .alpha., the rotors being arranged so that an axis of one of the rotors whose wings rotate in a rotary plane spaced farther from the guiding roller is offset back in direction perpendicular to an axis of the guiding roller by the magnitude a=d.multidot.cot .alpha. relative to the axis of the other of the rollers.
