A method of forming a heater assembly of an e-vaping device includes bending a wire to form a first lobe and bending the wire to form a second lobe. The first lobe and the second lobe form a generally sinuously-shaped heater having a first set of lobes and a second set of lobe. A first apex of the first lobe is generally opposite a second apex of the second lobe. The method may also include curling the first set of lobes towards the second set of lobes to form a heater having a substantially tubular form. The heater defines an opening there through.

The present disclosure relates to systems, apparatuses, and methods for assembling cartridges for aerosol delivery devices. The cartridges may be assembled by transporting carriages between various substations at which parts are added to a base. In another assembly method, the base may be moved between a plurality of robots which direct the base downwardly into contact with components to couple the components therewith. An inspection system may inspect the cartridges at various stages of completion.

A single or multiple cutters are pressed against end surfaces of a resistive element so as to form a plurality of notches in rims of the end surfaces. At this time, notches are formed such that notch depth at the end surfaces of the resistive element toward the axis center is smaller than notch length from the end surfaces of the resistive element to the axis. This allows easy cutting and removal of the resistance wire at the resistive element ends of a coil resistor, etc., and prevention of fraying of a wound wire at the resistive element ends.
