ABSTRACT:
This invention provides a reel1for a fine metal wire comprising a drum2, two flange bodies3, and two flange reinforcing members4each of them made of thin steel metal. Each flange reinforcing members4is bent into L-shape in cross-section such that a flange side portion4ais placed at a tilt angle θ of 4 +3/−3 degrees with respect to a vertical line. The flange side portion4aof the flange reinforcing member4is brought into intimate contact with a flange3bof 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.
