The former has removable discs on each end with a shallow taper. The material is wound onto the spindle using a guide piece which moves automatically along, to and fro, the width of the spindle, to ensure regular and even distribution of the coils. After the winding operation is completed, the spindle can be collapsed and removed from the coil. The tapered discs on the outside are now pressed flat, to enable the coil to be enclosed inside a container, which has a radial opening through which the material inside can be removed without a wire.
