ABSTRACT:
A machine for winding a filament, such as wire, on a normally stationary mandrel, the machine having a single winding element provided with guides for forming a filament loop on one side only of a rotational axis. Non-rotating feeding means supplies the filament to the rotating loop and means are provided for removing the turns from the mandrel. A binding or positioning element is fed from a supply located outside the zone of rotation of the winding element, the binding or positioning element being fed down inside the filament coils to secure them for removal from the mandrel. The binding or positioning element may be a wire or a solid rod supported by an extension of the mandrel which projects towards the filament feed. The mandrel extension may be an enlongated tube mounted in bearings in one or more fixed supports between the winding element and the filament feed. Different means are disclosed for restraining rotation of the mandrel, including gear wheels, bevelled gears, magnetic pole pieces and rotatable detents.
