ABSTRACT:
In winding coils of great wall thickness, such coils including a plurality of layers each formed of a plurality of figure-8s with the cross-overs progressing angularly around in each layer and with a radial hole extending from the outside of the coil into the axial opening thereof, by previous winding methods it is likely that the hole will be curved, even in cases where the guide for traversing the flexible material on the mandrel is spaced away from the mandrel and the outside of the wound material. In order to prevent the formation of a curved hole and to ensure that the hole is substantially radial, the guide carrier is moved in such a way that the line from the carrier to the surface of the coil always remains substantially tangential to the package at the same angular position in space with respect to the mandrel.
