ABSTRACT OF THE DISCLOSURE A method of producing a frustoconical support of the type formed by winding on to a conical spindle a shape which is produced repetitively by cutting from a web in such a manner that it contains the plan development surface of the truncated cone to be produced. The method is characterized in that it consists in cutting transversely web shapes in the form of juxtaposed contig- uous strips with transverse edges which are parallel and curvi- linear, and in winding each shape on to the spindle in overlapping helical manner and superposing a larger number of turns in the lower portion than in the upper portion. The support is parti- cularly useful for the reeling of textile threads.
