A mandrel useful in the spiral winding of flexible strip members is described including a pair of juxtaposed curvilinear perimetric driving portions which are offset laterally relative to one another and which have a slot or slots for receiving the elements to be wound. A process and winder are also described for the spiral winding of the strip members into a coiled element, e.g., a coiled capacitor or spirally wound battery cell pack.

A mandrel useful in winding together a plurality of flexible strip members, comprising: a first curvilinear perimetric driving portion; a second curvilinear perimetric driving portion juxtaposed from the first driving portion; an isthmus interconnecting the first and second driving portions and thereby defining with the first and second driving portions juxtaposed slots for receiving ends of the flexible strip members to be wound; and said first and second driving portions being offset generally laterally with respect to one another, in a direction parallel to the centerline passing through the openings of the slots, and in an amount from about 70 to about 85 percent of the combined thickness of the flexible strip members to be wound.
