Patent ID: 8505351

Claim:
A method for manufacturing a three dimensional core mass of at least one ribbon of metal comprising the steps of: modifying in a two-dimensional plane said ribbon to form a slot, channel or hole in said ribbon; and wrapping said modified ribbon onto at least one spooler with at least one wrap of said ribbon; wherein said modifying is activated by detection of at least one event from a slot template of pre-calibrated events that follows the movement of said spooler; wherein said pre-calibrated events are selected from a group consisting of angle, distance, speed, and time, and said detection is selected from a group consisting of light, magnetism, and electricity; wherein said spooler serves as a shaping template for said three dimensional core mass; wherein said three dimensional core mass is built up onto said spooler with at least one wrap of said modified ribbon at a time; wherein said modified ribbon extends per wrap in a radial direction from a rotation axis of said spooler.
