摘要
A process for the preparation of a band-shaped multi filament supra conductor with a plurality of superconducting conductor filaments, which in each case contain a metal-oxide superconductor material, the at least partially a bi - cuprate having a highly - tc.-Phase, in particular a function of the 2223 - has the type and of at least one normally conducting matrix material is surrounded, in which method a plurality of optionally preformed conductor elements, which is made of one of normally conducting material surrounding the superconducting material or a precursor material of the same, adjacent to each other in a coating of normally conducting material are arranged, and this arrangement is connected by means of a transverse section reducing treatment for the compression of the superconductor material is deformed, whereby the cross-section of the invention is to reducing treatment at least one rolling operation taking place by means of a rolling device comprises, in which the multifilament between two rollers (2) passes, characterized in that during at least one rolling operation at least the portion of the multi filament conductor between the two rollers (2) a - and, under a corresponding tensile stress is placed between a take-off device and a winding device is adjusted in dependence of a torque.
