Hvor forholdene tillater det, kan det være an-ordnet spor bare for annethvert (fig. 4) eller hvert tredje (fig. 5) viklingshode, the shaft 10 and wedged on it. In the slots 11, the individual winding heads 7 are inserted without clearance, which can be done by wedging with the help of the wedge pieces 9. Where the conditions permit, there can be a slot arranged only every second (fig. 4) or every third (fig. .5) winding head,
idet det er sørget for tangentiale forkilin-ger av de øvrige viklingshoder 8 i for-hold til de i sporene anbrakte. as provision has been made for tangential wedging of the other winding heads 8 in relation to those placed in the slots.
