Process for ultrasonic welding of thin walled parts |
摘要 |
Thin films (54, 56) are welded ultrasonically between a welding tool (12) and an anvil (14) that move together to clamp the films. The anvil (14) has a projection strip (41) that moves into a recess (46). The projection is located between a cosmetic seam and the sealing region and can be a separate exchangeable part (28). The recess (46) has tapered edges (48). An Independent claim is also included for the process of ultrasonic welding of films that includes deformation by a projecting part during welding. |
