<p>Method for the production of a metallic reel for spinning machines (10), in aluminum, an alloy thereof, and similar materials, comprising a cylindrical tubular body (11) to the ends of which (15, 16) respective flanges (12) are associated. The method comprises a step of obtaining the rough flanges (12), a step of obtaining the rough cylindrical body (1 1), and a step of connecting the flanges (12) to the cylindrical body (1 1) by means of friction welding. The connection step comprises a first leveling sub-step of the flanges (12) or the free ends (15, 16) of the cylindrical body (11), and a second sub-step of friction- welding the flanges (12) to the cylindrical body (11).</p> |
