Abstract

A method and an apparatus for minimizing the coil height of wire coils formed in a coil forming chamber, wherein individual wire windings are conveyed on a horizontal conveyor, the wire windings are allowed to drop at the end of the conveyor in an approximately vertically dropping movement, and the wire windings drop into the coil forming chamber so as to form the coil. The method includes the steps of placing the wire windings N from their drop line eccentrically relative to the axis of symmetry of the coil forming chamber, and adjusting an angle offset &Dgr;&phgr; between two successive windings in accordance with the number of wire windings which are placed per 360° in the coil forming chamber, wherein the adjustment is constant or variable, and wherein &Dgr;&phgr;=360°/N .
