Abstract: This invention provides a reel 1 for a fine metal wire comprising a drum 2, two flange bodies 3, and two flange reinforcing members 4 each of them made of thin steel metal. Each flange reinforcing members 4 is bent into L-shape in cross-section such that a flange side portion 4a is placed at a tilt angle ? of 4 +3/?3 degrees with respect to a vertical line. The flange side portion 4a of the flange reinforcing member 4 is brought into intimate contact with a flange 3b of the flange body to be fixed thereto by spot welding. As a result, a tensile stress is previously produced at the bent portion P, thereby substantially improving the strength and the repetitive usability.

Abstract: This invention provides a reel 1 for a fine metal wire comprising a drum 2 made of thin steel metal, two flange bodies 3 made of thin steel metal and engaged with both ends of inner periphery of the drum 2, and two flange reinforcing members 4 made of thin steel metal, for engaging with both ends of the drum 2, and for coming into contact with a substantially entire surface of a flange of each flange body 3 from a drum side. All of the drum 2, the flange bodies 3, and the flange reinforcing members 4 are welded together by spot welding. The flange reinforcing members 4 are fitted into flange bodies 3. Each flange reinforcing members 4 is bent into L-shape in cross section such that a flange side portion 4a is placed at a tilt angle &thgr; of 4 degrees+3/−3 degrees with respect to a vertical line. And each flange reinforcing member 4 is ring-shaped, which has the flange side portion 4a and a drum side portion 4b that are separated from each other with a bent portion P being a boundary therebetween.
