Abstract

Metallic wire/rod spooler (1) of the type with a mandrel with a vertical axis with a plurality of sectors (10) that move hinged at the base (11) in a discoidal base plate (14), in connection with upper petals (11) hinged on the upper part (110), from a position orthogonal to the mandrel axis (1-10) to form the wire/rod coil, to a position substantially directed upwards and with said sectors withdrawn at least on the upper part (10) to allow the extraction of the formed wire/rod coil, wherein it further comprises a wire insertion device (2) with a rectilinear entrance section (230) tangential to the mandrel (1-10) and a circular section (231-233) to adhere to said mandrel (1-10) as a circular arched continuation, with an arm (21) and forearm (23) that are articulated (22), operated by actuator means (24, 24') in three positions: I - a first position adhering to said cylinder mandrel (1-10) and to said base flange (14) for the entrance and conveying of the wire and the fixing of the wire in said clutch groove (141) in the flange (14); II - to a second position immediately adjacent, namely slightly detached from the first and actuated by sensor means of the completed clutch of the wire head in said groove (141) that at the same time allows said helicoidal ribbings present on the side sectors (10) in said groove (141) to pull said wire head further in said groove (141) by the speed difference existing between the advancement of the V-1 wire and the perpherical traction speed of the V-2 mandrel-reel, such that V1 <V2; III - an additional distant position outside the encumbrance of the formation of the coil when the advancing speed of the V-1 wire and the peripherical rotation speed of the mandrel are identical, namely in the condition of contemporary substantial speed V1=V2 that determines the prevalence of the speed imposed by mandrel rotation traction.
