Abstract
PURPOSE:To reduce the man-hour of winding, and to eliminate the need for the man-hour of epoxy molding, etc. by extending an elastic tube consisting of an insulating material around a coil and forming a sheath coating section on the outer circumference of the coil through shrinkage, fitting and arrangement. CONSTITUTION:The cylindrical coil bobbin 1, to both ends thereof collar sections 1A, 1B are shaped, is molded with a plastic material, and the bobbin 1 is fitted into a guide jig 3 winding a coil 2 composed of a copper wire on the outer circumferential section of the cylinder of the bobbin 1. The elastic tube 4 is fitted and arranged onto the outer circumference of a guide tapered section 5 under a condition that it is exended. When a traction jig 6 is right moved, the tube 4 crosses the collar section 1A of the coil bobbin 1 while the inside diameter is extended along the guide tapered section 5, and is right moved coating the upper section of the coil 2. When a clamping tool 7 is loosened, the tube 4 is returned and shrunk to the original condition.
