Definitions

  • the object of the present patent application is a reel for holding coils of metal wire, constructed by arc-welding pre-formed elements made from metal rod together once they have been suitably shaped and poritioned.
  • Reels constructed from a number of suitably shaped and welded metal rods forming a skeleton like reel are currently already on the market. These reels consist of a central hub and two circular side pieces that hold the coil of wire wound around the hub of the reel in place.
  • the perfect construction of the hub is in fact of primary importance to the correct formation of the coil of wire it is to hold.
  • the individual loops of wire must be placed one beside the other and one above the other in an orderly fashion to avoid the the wire jamming and consquently breaking, a dangerous occurance, when the wire is unwound from the reel.
  • reels are designed to be placed on horizontal-axis adaptor drums on special machines that are capable of automatically winding or unwinding coils of wire.
  • the scope of the present invention is that of finding a new and advantageous method for combining the various shaped metal rod elements that form the skeleton of a reel, so that all these elements can be simultaneously arc-welded under optimum conditions for the extremely precise construction of the reel in question, with reference to the internal diameter of the central hub and its perfect circularity.
  • reels are formed of two identical rings made of metal rod, that are placed in a parallel and co-axial position and connected together by a number of transverse radial spokes, each consisting of a metal rod that has been bent into a 'U' shape, whose vertical arms are welded by their ends to the two aforementioned rims, thus forming, together with the aforementioned radial arms, the two sides that hold the coil of wire in place.
  • the central hub is shaped like a circular cage whose bars are formed by the central sections of each of the radial. 'U' shaped rods, or spokes.
  • Each of the two plates has radial grooves corresponding to each of the spokes to be welded, so that the vertical arms of the spokes fit into the centre of these grooves where they can easily be reached and gripped by one of the vice-shaped electrodes on the welding machine.
  • the other electrode on the machine presses against the external edge of the rim, in correspondence with the contact point between the spoke and the rim.
  • the centripetal pressure exerted by the external electrodes not only ensures the rim is held in shape and position, but also presses the radial spokes against the central drum, so that at the moment the spokes are welded, their central sections are all placed and held against the same cylindrical surface.
  • the welding machine consists of a ring-shaped series of pairs of electrodes that simultaneously operate on all the points to be welded, and hold the radial arms of the spokes near their ends whilst pressing the external rim against the ends of the aforementioned arms.
  • the model according to the invention consists of a reel for cables (1), constructed of several pieces of pre-formed and suitably shaped iron rod that are arc-welded together
  • transverse spokes (1a) are used to construct the reel, each of which is made from a length of metal rod bent into a 'U' shape.
  • the special feature of the model according to the invention consists of the fact that the ends of the vertical arms on each spoke (1a) are pressed against the internal circumferences of the two rims (1b) in such a way that these arms are held on the same plane as the respective rim (1b) to which they are welded.
