Title (EN) SONOTRODE FOR ULTRASOUND WELDING AND CUTTING PACKAGING UNITS
(FR) SONOTRODE POUR UNITÉS DE CONDITIONNEMENT DE SOUDAGE À ULTRASONS ET COUPE
Abstract: front page image
(EN)A sonotrode (14) having, at one end, an active sealing surface (17) that cooperates with the hard-metal cutting edge (22) of a blade (21), and having a cavity (23) substantially tangent to the active sealing surface (17) and communicating with the outside through a slit (24) formed along the active sealing surface (17) at a contact area between the active sealing surface (17) and the cutting edge (22); the sonotrode (14) having a reinforcing member (25), which is coaxial with the cavity (23), is wider than the slit (24), is fitted inside the cavity (23) to close the slit (24), and has a surface hardness greater than that of the sonotrode (14) at the active sealing surface (17) and substantially equal to that of the cutting edge (22) of the blade (21).
(FR)L'invention concerne une sonotrode (14) ayant, à une extrémité, une surface de scellement active (17) qui coopère avec l'arête de coupe de métal dur (22) d'une lame (21), et ayant une cavité (23) sensiblement tangente à la surface de scellement active (17) et communiquant avec l'extérieur à travers une fente (24) formée le long de la surface de scellement active (17) à une zone de contact entre la surface de scellement active (17) et l'arête de coupe (22); la sonotrode (14) ayant un élément de renforcement (25), qui est coaxial avec la cavité (23), est plus large que la fente (24), est ajusté à l'intérieur de la cavité (23) pour fermer la fente (24) et a une dureté de surface supérieure à celle de la sonotrode (14) au niveau de la surface de scellement active (17) et sensiblement égale à celle de l'arête de coupe (22) de la lame (21).
