An arrangement for forming a packing unit from an endless tube, comprises an ultrasound welding unit (2) with an anvil (4) and a sonotrode (3), both of which can move towards each other, and a unit for positioning the tube material to be welded between the anvil and the sonotrode. An arrangement for forming a packing unit from an endless tube, comprises an ultrasound welding unit (2) with an anvil (4) and a sonotrode (3), both of which can move towards each other, and a unit for positioning the tube material to be welded between the anvil and the sonotrode. The anvil has two sections (4a,4b) which can be moved towards the sonotrode. One section is used as the closure anvil while the other is used as the separation anvil. Both anvil sections are plate shaped, and the closure anvil has a pressure surface that runs parallel to the sonotrode end face. |
