Проволоки повива 8 зажимаются между внешней конической поверхностью внутренней конусной втулки 6 и внутренней конической поверхностью втул5 ки 7 при помощи гаек 17, одновременно происходит зажим проволок повива 13 между внутренней конической поверхностью втулки 6 и сужающимся концевым участком основания 1. Кольцом 11 отгибают концы проволок повива 8 и при помощи гаек 18 зажимают их между коническими поверхностями кольца 11 и втулки 7. Кольцом 12 отгибают концы проволок повива 13 и при помощи 15 гаек 19 зажимают их между коническими поверхностями кольца 12 и втулки 6.The coils of wire 8 are clamped between the outer conical surface of the inner cone sleeve 6 and the inner conical surface of the sleeve 5 with nuts 17, at the same time, the wires of the coils 13 are clamped between the inner conical surface of the sleeve 6 and the tapering end portion of the base 1. The ends of the wires of the coils 8 are bent and with the help of nuts 18, clamp them between the conical surfaces of the ring 11 and the sleeve 7. With the ring 12, the ends of the wires of the twine 13 are unbent and with the help of 15 nuts 19 clamp them between the conical surfaces of the count pg 12 and bushings 6.
