A method of forming a coil-wound article comprises: winding a first coil by laps clockwise around a first swath, counterclockwise around a second swath, and clockwise around a third swath of hooks out of slots along an outer periphery of a mandrel, wherein the hooks are collapsibly protruded from within the mandrel through the slots and consecutively grouped into the first to third swaths each at least having a first to third hook; winding a second coil by laps clockwise around from between the first and second hooks of the first swath to between the first and second hooks of the second swath, counterclockwise around from between the first and second hooks of the second swath to between the first and second hooks of the third swath, and clockwise around from between the first and second hooks of the third swath to between the first and second hooks of the first swath; winding a third coil by laps clockwise around from between the second and third hooks of the first swath to between the second and third hooks of the second swath, counterclockwise around from between the second and third hooks of the second swath to between the second and third hooks of the third swath, and clockwise around from between the second and third hooks of the third swath to between the second and third hooks of the first swath; and releasing the wound first-to-third coils axially from the mandrel by collapsing the hooks below the outer periphery.
