<p><P>PROBLEM TO BE SOLVED: To provide a sealing apparatus which excels in mass productivity with simple design and can make a uniform seal also, and to provide a manufacturing method of a soft article having a sealed portion. <P>SOLUTION: In the sealing apparatus, as a drum (5) and a rotary base (6) are rotated together, a follower (10a) of a swinging support member (9) swingably 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 swinging support member (9) to swing. When the rotary drum (5) reaches a predetermined rotational position, an anvil (14) supported by the swinging 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 swinging motion of the swinging support member (9), entire operation becomes quite simple, and a continuous soft workpiece can be certainly clamped between the horn (8) and the anvil (14). <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
