gripping section 30 u2032 during the movements of the manipulator 30 wires w do not cross each other when routed along the trajectories and wound in the helixes of the twisted portions surfaces 31 and 32 can be cylindrical sides respectively of portions 31 u2032 and 32 u2032 of member 23 see fig2 and 3 and can be located over coil ends 14 see also fig4 as a result the leads reach slots like 26 and 27 by being routed along predetermined paths which follow the contour of surfaces 31 and 32 portions 31 u2032 and 32 u2032 can be received in recesses of member 22 as shown for example in fig2 and 4 at slots like 26 and 27 the manipulator draws the leads through the radial passage portions in order to locate the end portions of the leads within seats 28 and 29 u2014 see for example fig4 to 6 as illustrated in fig5 and 6 the manipulator can first move to draw the plural wires against surfaces 31 and 32 and then into slots like 26 and 27 to reach the required position in seats 28 and 29 and alignment in predetermined directions 33 and 34 a lead like 17 shown in fig6 that is coming from two separate slots of the stator can be brought into slot 26 and seat 28 in two stages i e in a first stage lead portion 17 a can be.
