Abstract

L'invention concerne une bobineuse pour produire des bobines de fils de connexion étamés, ladite bobineuse comprenant un outil de bobinage (2) dans lequel une fente de bobinage (6) peut être créée, une alimentation en fil (15), un outil de coupe (16), des éléments d'entraînement, un élément de commande, et un bain de soudure (20) pouvant être déplacé par rapport à l'outil de bobinage et servant à l'étamage des fils de connexion de la bobine. Ce dispositif est particulièrement adapté à la production de bobines sans noyau. L'invention concerne également un procédé correspondant, pour commander ladite enrouleuse, ledit procédé faisant appel à un bain de soudure avec des fentes d'introduction pour les fils de connexion. Ce procédé assure un étamage net et sans résidu des fils de connexion de la bobine, et évite de devoir retirer les fils de l'outil de bobinage pour réaliser l'étamage. Les avantages du dispositif et du procédé de l'invention résident dans le fait que la facilité d'intégration d'un bain de soudure et d'un dispositif de distribution du bain de soudure dans la bobineuse simplifie considérablement la production de bobines de fils de connexion étamés.
