Abstract

PURPOSE:To uniform the winding pitch, by a method wherein a conical and helical spring is provided inside a winding nozzle retained by a holder, and the winding nozzle is rotated, thereby to change the inside diameter of the minimum turn of the spring. CONSTITUTION:A winding nozzle 1' is secured to a winding nozzle holder 4 by means of a set bolt 5. A conical helical spring 6 is disposed inside the nozzle 1'. One end 6a of the spring 6 is secured to a projection 4a provided on the holder 4, and the other end 6b is retained by a notch 1'b formed in the nozzle 1'. The inside diameter of the minimum turn of the spring 6 is changed by rotating the nozzle 1'. Therefore, when a core material 2 is passed through a bore 1'a in the nozzle 1', the set bolt 5 is loosened to rotate the nozzle 1' in the direction for enlarging the minimum turn inside diameter. After the core material 2 is passed, the nozzle 1' is rotated in the opposite direction to reduce the minimum turn inside diameter so that it will match to the diameter of the core material 2. Consequently, the gap between the diameter of the core material 2 and that of the bore 1'a is filled to uniform the winding pitch.

Description

【発明の詳細な説明】 本発明は巻線機における巻線ノズルの孔径を調整するこ

One end 6a is fixed by a projection 4a provided on the winding nozzle holder 4, and the other end 6b is fixed to the winding nozzle 1.
It is fixed by a notch 1'b provided at '. The minimum winding inner diameter of this spring 6 can be changed by rotating the winding nozzle 1'. Therefore, when passing the core material 2 through the hole 1/a of the winding nozzle 1', loosen the set port 6 and move the winding nozzle 1 in the direction that widens the minimum winding inner diameter of the spring 6.
', and after passing the core material 2, turn the winding nozzle 1' in the opposite direction, and adjust the minimum winding inner diameter to match the diameter of the core material 2. The gap in the diameter of the hole 1'a of the winding nozzle 1' can be substantially filled, the swinging of the core material 2 when the winding material 3 is wound around the core material 2 is suppressed, and the winding pitch is kept constant. be done.
