Self-centering fixture 3c

The operator places the orange bar on of two driven screws of two opposite-hand threads. The bar will be centered automatically.
This principle is also used to guide the moving wire to the center shown in the final scenes of the video. In that case the screw is driven by the bar.
This video was made based on the picture on page19-3 of the book:
Illustrated Sourcebook of Mechanical Components, Robert O. Parmley, P.E. 2000.
