The ultrasonic welding apparatus takes a plastics workpiece (12) between an ultrasonic sonotrode (10) and an anvil (16). The sonotrode and anvil have surfaces (14,18) to bear against the workpiece. The anvil surface has at least one welding zone (22,24) and an adjacent cutting zone to take a cutting edge (42) at the sonotrode. |
