Abstract

A.PROCEDE DE SOUDAGE PAR ULTRA-SONS D'UNE FEUILLE EN MATIERE THERMOPLASTIQUE SOUPLE SUR UN CORPS EN MATIERE THERMOPLASTIQUE RIGIDE. B.CE PROCEDE CONSISTE A PLACER LE CORPS RIGIDE SUR UNE PREMIERE SONOTRODE, A POSITIONNER LA FEUILLE SOUPLE SUR LA PARTIE DU CORPS RIGIDE A LAQUELLE ELLE DOIT ETRE SOUDEE, A APPLIQUER SUR LA FEUILLE SOUPLE UNE SECONDE SONOTRODE, LAQUELLE EST GRAVEE SUIVANT UNE SUCCESSION DE POINTES EN RELIEF ET EST PARFAITEMENT AJUSTEE A LA PARTIE DU CORPS REVETUE DE LA FEUILLE, ET A EMETTRE DES VIBRATIONS ULTRASONORES ENTRE LES DEUX SONOTRODES PENDANT QU'UNE PRESSION APPROPRIEE EST EXERCEE SUR LES PIECES A SOUDER. C.APPLICATION AU REVETEMENT DE LA BARRETTE DE CLIPSAGE DES PARE-SOLEIL POUR VEHICULES.A. ULTRA-SOUND WELDING PROCESS OF A SHEET OF SOFT THERMOPLASTIC MATERIAL ON A BODY OF RIGID THERMOPLASTIC MATERIAL. B. THIS PROCESS CONSISTS OF PLACING THE RIGID BODY ON A FIRST SONOTRODE, POSITIONING THE SOFT SHEET ON THE PART OF THE RIGID BODY TO WHICH IT MUST BE WELDED, APPLYING A SECOND SONOTRODE ON THE FLEXIBLE SHEET, WHICH IS ENGRAVED FOLLOWING A SUCCESSION POINTS IN RELIEF AND IS PERFECTLY ADJUSTED TO THE SHEET COATED PART OF THE BODY, AND TO EMIT ULTRASONIC VIBRATIONS BETWEEN THE TWO SONOTRODES WHILE APPROPRIATE PRESSURE IS EXERCISED ON THE PARTS TO BE WELDED. C. APPLICATION TO THE COATING OF THE CLIP BAR OF VEHICLE SUN VISORS.
