Title (EN) METHOD TO FASTEN ELEMENTS AS BUTTONS TO A TEXTILE MATERIAL AND AN APPARATUS FOR CARRYING OUT THE METHOD
(FR) APPAREIL ET METHODE DE FIXATION D"ELEMENTS TELS QUE DES BOUTONS SUR UN MATERIAU TEXTILE
Abstract: front page image
(EN)A method to fasten an element as buttons to a textile material, which element (76) is made of plastic material and comprises a main body (77) intended to be positioned on the one side of the textile material (79) and a projection (78) which at least partly shall extend through the textile material and be deformed to a deformation head on the opposite of the textile material relative to the side, where said main portion is positioned. The method is characterized by the deformation head being formed by means of a tool (60) subjected to oscillations in the ultrasonic range being pressed against the end of the projection (78) in such a way that the material of the same by yielding forms the deformation head, and by the projection in at least the inner portion which occupies a position between the deformation head formed and the main portion of the object being designed with a smoothly developing profile without any abrupt sectional changes and with a rounded passage blending into the main portion. The invention also relates an apparatus for performing a form of he method by application of buttons 76) to pieces of garment and similar, which buttons are arranged in a group of a determined formation, the piece of garment being provided with button openings, as for example button holes (81) in a corresponding formation, together with which button holes the buttons are buttoned up when the method is carried out in the apparatus.
(FR)Methode de fixation d"elements tels que des boutons sur un materiau textile; les elements (76) sont faits en matiere plastique et comprennent un corps principal (77) destine a etre place d"un cote du materiau textile (79) et une saillie (78) dont une partie au moins traverse le materiau textile et est deformee pour former une tete du cote oppose au materiau textile, ou est place le corps principal. La methode est caracteristique en ce que la tete de deformation est formee au moyen d"un outil (60) soumis a des oscillations ultrasoniques qui presse le bout de la saillie (78) de telle maniere que le materiau de cette derniere, en cedant, forme la tete de deformation, et en ce qu"au moins la partie intermediaire de la saillie comprise entre la tete de deformation et le corps principal possede un profil tres adouci sans changement brusque de section et avec une jonction tres arrondie avec le corps principal. L"invention concerne aussi un appareil pour appliquer la methode en fixant des boutons (76) sur des vetements et autres, ces boutons etant disposes suivant une formation determinee, le vetement etant pourvu de boutonnieres (81) dans une formation correspondante, dans lesquelles les boutons sont fixes a l"aide de l"appareil selon la methode.
