Abstract:
1. A demountable reel ( 1 ), comprising a hollow cylindrical central body ( 2 ), divided in two equal semi-cylindrical halves ( 3 ) by a diametral plane, and two essentially flat discs ( 4 ), of greater diameter and equipped with central openings ( 14 ), arranged on the bases of the hollow cylindrical central body, characterized in that the semi-cylindrical halves are equipped, on rims of their bases ( 5 ), with flanges ( 6 ) projected transversally from the semi-cylindrical halves, and in that each disc is equipped, on its inner face ( 8 ), with an annular groove ( 7 ), which defines a discontinuous guide rail ( 9 ) adapted to removably receive the flanges of one of the ends of the semi-cylindrical halves of the hollow cylindrical central body, at least one of the guide rail and the flanges of the semi-cylindrical halves having segments with a cross section that varies over a length thereof, causing, when the hollow cylindrical central body is rotated in relation to the discs, that the clearance between the flanges and walls of the guide rail which house the flanges is reduced until it disappears, all the flanges being simultaneously wedged to the guide rail, and rotating said central body in the opposite direction separating the discs.
