ABSTRACT:
An arrangement for laying a wire in circular windings by bending the wire to circular form during simultaneous twisting includes a wire conveying device and a consecutively arranged laying head including a rotating laying pipe, whose central axis is oriented tangentially to the wire axis on the wire entry end and which gradually passes from the entry end into a circular arc directed approximately perpendicular to the axis of rotation, its center lying on the axis of rotation. A twisting device is provided between the wire conveying means and the laying head. In order to be able to lay wires of larger diameters in closely adjacent windings, the twisting device is formed by a bent pipe twisting the wire under positive locking and frictional engagement.
