A system for bundling a plurality of high temperature superconductor tapes into a flexible cable, includes a first alignment device for receiving and guiding there through the plurality of high temperature superconductor tapes, each of the tapes arranged with a wide surface oriented at a first angle. There is a second alignment device for receiving and guiding there through the plurality of high temperature superconductor tapes, each of said tapes arranged with the wide surface oriented at a second angle. The first angle is transverse to the second angle and plastically deforms the tapes to impart a twist pitch in the tapes. There is a forming member spaced from the second alignment device for receiving the plurality of high temperature superconductor tapes with the imparted twist pitch and forming them into a bundle of high temperature superconductor tapes of the high temperature superconductor tapes with the imparted twist pitch.
