Abstract

La invencion se refiere a un arreglo en un equipo (2) de accionamiento para una unidad (1) de sellado ultrasonico. El equipo (2) de accionamiento es del tipo que tiene un numero de placas (7) de cerámica, piezoeléctricas colocadas con hojas (8) metálicas, conductivas interyacente, acopladas a una fuente de c.a. Las placas (7) cerámicas y las placas (8) metálicas se mantienen conjuntamente con un contrapeso (9) mediante un tornillo (10) de sujecion que asegura parcialmente el equipo (2) de accionamiento a la unidad (1) de sellado ultrasonica, y realiza parcialmente una fuerza de sujecion en el equipo (2) de accionamiento. El contrapeso (9) tiene un diámetro interior y un diámetro exterior. Para tener una carga de presion uniforme en las placas (7) cerámicas, se proporciona una ranura (12) en el diámetro interior el contrapeso (9).
