Abstract

Apparatus and process for winding filamentary material in a figure 8 configuration including a rotatable spindle for retaining a mandrel upon which the filamentary material is wound; a traverse mechanism for controlling the laying of wound coils on the mandrel; and controlling the advance of the wound layers on the mandrel in accordance with the rotation of the spindle and the movement of the traverse mechanism to vary the angular displacement of the wound coil so that the number of crossovers of succeeding layers of the wound coils increases as the winding process progresses, thereby increasing the density of the wound coils.
