Abstract
In a method and a device for winding an acentric coil former, the coil former is set into a rotary motion with a winder drive, wherein the rotary motion of the coil former causes a wire attached to the coil former to be wound onto the coil former and unwound from a drum operatively connected to a brake drive, and the winder drive or the brake drive, or both, are controlled based on a rotation position of the coil former. The wire is unwound from the drum with a non-constant speed.
