confining member 78 receive distal ends 18 of blades 12 and permit movement of confining member 78 from its upper position to its lower position in the upper position of confining member 78 wire 46 pushed from dispensing end 36 of tube 72 impinges on inner surface 80 of member 78 at points lying on circle 92 fig3 thus confining the wire so pushed to a first circular path aligned with slots 16 1 16 2 in the lower position of confining member 78 wire 46 pushed from dispensing end 36 of tube 72 impinges on surface 80 at points lying on circle 94 thus confining the wire so pushed to a circular path smaller than path 92 which is aligned with slots 16 3 16 4 thereby placing two concentric coils one within the other on blades 12 it will be readily understood that while confining member 78 has been shown and described as having two i e upper and lower positions thereby providing for the placing of two concentric coils on blades 12 confining member 78 may have one or more intermediate positions thereby providing for the placement of three or more concentric coils on blades 12 following the placing of one set of concentric coils on blades 12 as above described the circular array of blades 12 may be rotated by index drive motor 56 to another rotational position and another set of coils placed on blades 12 as above described while axes 28 and 14 have been shown and described as being parallel they may be relatively inclined d while there have been described above the principles of this invention in connection with specific apparatus it is to be clearly understood that this description is made only by way.
