Metallic wire/rod spooler (1) of the type with a mandrel with a vertical axis with a plurality of sectors (10) that move hinged to the base (11) in a discoidal base plate (14), in connection with upper petals (11) hinged on the upper part (110) of said mandrel that moves from a position orthogonal to the mandrel axis (110) to form the wire/rod coil, to a position substantially directed upwards to allow the extraction of the formed wire/rod coil, and comprising safety means against the movement of said sectors (10) during the formation of said coil, wherein three fixing means are provided for safety before the start of rotation and during the rotation of said mandrel (1-10):I - said petals in the hinging (110) have a tooth (111) that in lowering rotation of coil formation, externally fix the respective sector (10) on the upper part to couple it against the centrifugal force, forming the first upper safety joint (e); II - said sectors (10) are embedded downwardly within the base flange (14) to form the second safety joint against the centrifugal force (IN) and III - an internal T-shaped intermediate tooth (101) being provided as an extension of each sector (10) that is fixed within a female groove also Tshaped with clearance (1230) of a central connection body (123) of said mandrel. |
