Pod omenjeno elektrodo je na voljo nepremakljiva elektroda, na katero sta namestljiva vsakokrat za zvarjenje predvidena kovinska predmeta. Po premiku premakljive elektrode v smeri navzdol elektroda nasede na enega izmed kovinskih delov, nakar skozi omenjeno premakljivo elektrodo, omenjena kovinska predmeta in omenjeno nepremakljivo elektrodo steče električni tok. Zaradi električne upornosti omenjenih kovinskih predmetov se slednja intenzivno segrejeta vsaj na svojih medsebojno nalegajočih površinah vsaj deloma stalita. Po prekinitvi električnega toka se omenjena kovinska predmeta zahvaljujoč pritisku omenjene premakljive elektrode med ohlajanjem sprimeta in s tem medsebojno zvarita.2005/0284848 Al oz. EP 1 579 943 BI and comprises a movable electrode attached to the underside of the support plate together with the movable electrode in a vertical direction. Below that electrode there is a non-slip electrode to which metal objects are provided for welding each time. After moving the movable electrode in the downward direction, the electrode engages one of the metal parts, and then through said movable electrode, said metal object and said non-movable electrode electrocute. Due to the electrical resistance of the aforementioned metal objects, the latter are intensely heated at least partially on one another on their contact surfaces. Upon interruption of the electrical current, said metal objects, by virtue of the pressure of said displacement electrode, adhere to each other during cooling and thereby weld.

Med temu sledečim približevanjem nosilnih elementov 1, 2 zgornja varilna elektroda 520 naleti na kovinski predmet M na površini traku B, ki je podprt s spodnjo varilno elektrodo 510. V tem trenutku se sklene električni tokokrog skozi omenjeni elektrodi 510, 520, kot posledica prehajanja električnega toka vsakokrat vnaprej določene jakosti skozi omenjen kovinski trak B vnaprej določene električne upornosti in na njegovi površini in z njim v električnem stiku razporejen kovinski predmet M prav tako vnaprej znane električne upornosti se v omenjenem traku B in kovinskem predmetu M generira toplota. Zaradi omenjene generirane toplote se omenjen trak B in kovinski predmet M segrejeta vsaj na njunih stičnih površinah segrejeta na temperaturo taljenja oz. plastifikacije in zaradi njunega medsebojnega pritiska kot posledice medsebojnega pritiska med varilnima elektrodama 510, 520 tudi zvarita.When the device according to FIG. 1, a continuous metal strip B is inserted into the guide 31 of the feeder assembly 3 and a certain amount of small metal objects M is brought into the feeder reservoir 41, the support elements 1, 2 are spaced apart, and the electrical circuit through the electrodes 510, 520 of the welding assembly 5 is broken. The available small metal objects M are sorted in the router 42 and, prior to the respective approximation of the supporting elements 1, 2, one of the mentioned metal objects M enters the guide 42 of the feed assembly 4, after which it moves towards the surface of the strip B and remains there in a predetermined position between the two welding electrodes 510, 520. During this subsequent approximation of the supporting elements 1, 2, the upper welding electrode 520 encounters a metal object M on the surface of the strip B supported by the lower welding electrode 510. At this moment, an electrical circuit is made through said electrodes 510, 520, as a result of the passage of an electric current of a predetermined current through said metal strip B of a predetermined electrical resistance and a metal object M arranged thereon, and a metallic object M arranged in the same way, as well as electrical resistances known in advance in said band B and metal object M is generated by heat. Because of the heat generated, said strip B and the metal object M are heated at least at their junction surfaces to the melting temperature or the melting point. plasticisation and due to their mutual pressure as a result of the mutual pressure between welding electrodes 510, 520 are also welded.
Temu sledi ponovno medsebojno razmikanje nosilnih elementov 1, 2 in posledično tudi varilnih elektrod 510, 520, pri čemer sta zvarjena trak B in kovinski predmet M prepuščena ohlajanju, obenem pa se izvrši premik omenjenega traku B v vodilu 31 podajalnega sklopa 3 za vnaprej določeno razdaljo v vzdolžni smeri X naprave v smislu napredovanja traku B skozi napravo, nakar na površino traku B iz vodila 42 dovajalne enote 4 dospe nadaljnji droben kovinski predmet M. Sledi korak ponovnega medsebojnega primikanja nosilnih delov 1, 2 in varilnih elektrod 510, 520 z aktiviranjem električnega tokokroga skozi slednji, pri čemer se po izbiri v primernem rezalnem sklopu 6, kadar je naprava s tovrstnim sklopom opremljena, ob primikanju omenjenih nosilnih elementov 1, 2 izvrši tudi ločitev enega izmed odsekov traku B, na katerega površino je bil v enem od predhodnih korakov že privarjen droben kovinski predmet M.This is followed by a re-spacing of the supporting members 1, 2 and, consequently, of the welding electrodes 510, 520, leaving the welded strip B and the metal object M to cool, while moving said belt B in the guide 31 of the feeder assembly 3 for a predetermined distance in the longitudinal direction X of the device in the sense of advancing the belt B through the device, and then on the surface of the belt B from the feeder unit 42 42 receives a further fine metal object M. This is followed by the step of re-moving the supporting parts 1, 2 and the welding electrodes 510, 520 by activating the electrical the circuit through the latter, optionally in a suitable cutting assembly 6, when fitted with such assembly, by moving said support elements 1, 2 also to separate one of the sections of tape B onto which the surface was in one of the preceding steps already welded fine metal object M.
