Disclosed is a sealing apparatus wherein, as a drum (5) and a rotary base (6) are rotated together, a follower (10a) of a rocking support member (9) rockably provided on the outer periphery of the rotary base (6) is guided along a cam groove (15c) of a cam member (15) to drive the rocking support member (9) to rock. When the rotary drum (5) reaches a predetermined rotational position, an anvil (14) supported by the rocking support member (9) is urged onto a horn (8), and then, when it reaches another rotational position, the anvil (14) is moved away from the horn (8). Since the anvil (14) is driven by the rocking motion of the rocking support member (9), entire operation becomes quite simple, and a continuous soft work can be certainly clamped between the horn (8) and the anvil (14).
L'invention concerne un appareil d'étanchéité dans lequel, pendant qu'un tambour (5) et une base rotative (6) tournent l'un par rapport à l'autre, un dispositif d'entraînement (10a) d'un élément de support basculant (9) est monté basculant sur la périphérie extérieure de la base rotative (6) guidée le long d'une rainure de came (15c) d'un élément de came (15) en vue de faire basculer l'élément de support basculant. Lorsque le tambour rotatif (5) atteint une position de rotation prédéfinie, une enclume (14) supportée par l'élément de support basculant (9) est poussé contre une bigorne (8), puis, lorsqu'il atteint une autre position de rotation, l'enclume (14) est éloignée de la bigorne (8). Dès que l'enclume (14) est entraînée par le mouvement basculant de l'élément de support (9), toute l'opération devient relativement simple, et un travail tendre continu peut être fixé entre la bigorne et l'enclume (14).
