Method for making reinforcements for reinforced concrete, comprising the steps of: a. prearranging in a loading station a series of longitudinal elements suitably distanced one another on a work plane defined by support means for supporting said longitudinal elements b. feeding said longitudinal elements, through shifting on said work plane, to a joining station provided with joining means carried overhung from the top in a way as to leave an empty space with respect to said work plane on which are fed said longitudinal elements; c. joining to said longitudinal elements at least a transverse element prearranged in said joining station through actuation of said joining means, said joining means comprising a plurality of welding heads each provided with a first upper electrode; d. joining in ordered succession possible further transverse elements to said longitudinal elements to complete the realization of the structure constituted by the joining of said longitudinal elements and said possible further transverse elements; characterised in that: - said empty space left by said joining means above said work plane is suitable to allow the passage of possible folds shaped on the longitudinal elements; - each first upper electrode is associated to a respective second lower electrode to form respective couples of electrodes (31, 37), suitable to operate in contraposition at the junction between a said longitudinal element and said at least a transverse element to be welded; each said welding heads being further provided with an openable contact connected to a respective first upper electrode to open / close the electric circuit of the respective couple of electrodes (31, 37); - said plural welding heads are operable to be laterally shifted to allow the passage of possible folds, and further carry said first upper electrodes overhung forward and/or transversally to allow the insertion and welding of longitudinal elements and/or transverse elements shaped according to any profile also with a closed profile. a. prearranging in a loading station a series of longitudinal elements suitably distanced one another on a work plane defined by support means for supporting said longitudinal elements b. feeding said longitudinal elements, through shifting on said work plane, to a joining station provided with joining means carried overhung from the top in a way as to leave an empty space with respect to said work plane on which are fed said longitudinal elements; c. joining to said longitudinal elements at least a transverse element prearranged in said joining station through actuation of said joining means, said joining means comprising a plurality of welding heads each provided with a first upper electrode; d. joining in ordered succession possible further transverse elements to said longitudinal elements to complete the realization of the structure constituted by the joining of said longitudinal elements and said possible further transverse elements; - said empty space left by said joining means above said work plane is suitable to allow the passage of possible folds shaped on the longitudinal elements; - each first upper electrode is associated to a respective second lower electrode to form respective couples of electrodes (31, 37), suitable to operate in contraposition at the junction between a said longitudinal element and said at least a transverse element to be welded; each said welding heads being further provided with an openable contact connected to a respective first upper electrode to open / close the electric circuit of the respective couple of electrodes (31, 37); - said plural welding heads are operable to be laterally shifted to allow the passage of possible folds, and further carry said first upper electrodes overhung forward and/or transversally to allow the insertion and welding of longitudinal elements and/or transverse elements shaped according to any profile also with a closed profile.
