<p>There is described herein an improved apparatus (1) suitable for supporting and orientating in a balanced fashion the sharply elongated mandrel (3) during winding of superconducting wires for forming magnetic coils. There is provided a number of apparatus for controlling the mandrel (3) orientation, in spaced apart locations along the latter, in order to reduce torsional effects, and a number of supporting apparatus substantially identical to the previous apparatus except for lacking the drive means, in order to reduce bending effects on said mandrel. They are based on the use of positive or shift-free transmissions and of links providing a mechanical parallelogram system for moving the mandrel (3) which, in such a way, may perform a complete rotation, from -90 DEG to +90 DEG , relative to the vertical, without any obstacle from above the mandrel supporting bar (2), which may interfere with the winding of the conducting wire when said mandrel (3) is located in one of the two end positions.</p> |
