Abstract

Procédé et dispositif pour assembler des branches opposées d'éléments d'accouplement moulés pour fermetures à glissière ou à curseur. Le procédé comprend essentiellement trois phases opératoires, à savoir de pressage des branches opposées précitées contre une tête ultrasonique comportant une partie centrale d'épaisseur uniforme et deux extrémités amincies; de fusion desdites branches opposées sur leurs surfaces internes se faisant vis-à-vis; et de pressage les unes contre les autres desdites branches après dégagement d'avec la tête ultrasonique de manière à réaliser l'assemblage de leurs surfaces internes qui ont été fondues
