Abstract:
A winding apparatus having a convex form and a concave form for forming a horizontal deflection coil utilized for a deflection yoke being mounted on a neck portion of a color picture tube, wherein said horizontal deflection coil is formed by winding a wire in a winding space between said convex form and said concave form, said neck portion corresponding to a smaller diameter section, a screen side of said color picture tube corresponding to a larger diameter section, and an area connecting said smaller diameter section and said larger diameter section as a side section, said winding apparatus comprising:a plurality of dividing pins of regulating winding distribution in said side section by being inserted in said winding space while winding said wire, said plurality of dividing pins further comprising: a first dividing pin being provided within a range of 20 to 35% of a length between said larger diameter section and said smaller diameter section in a direction from said larger diameter section to said smaller diameter section and within an angle of 10 to 25 degrees to a horizontal axis of said screen and a line connecting said first dividing pin and an axial line of said color picture tube viewed from a cross section at a position of inserting said first dividing pin in said winding space; and a second dividing pin being provided within a range of 55 to 70% of a length between said larger diameter section and said smaller diameter section in a direction from said larger diameter section to said smaller diameter section and within an angle of 25 to 40 degrees to the horizontal axis of said screen and a line connecting said second dividing pin and the axial line of said color picture tube viewed from a cross section at a position of inserting said second dividing pin in said winding space.
