摘要： The present invention refers to an apparatus and a method for forming a packaging unit consisting of an endless hose, or for sealing a prefabricated packaging unit, comprising an ultrasonic welding device including an anvil and a sonotrode, which are movable towards each other, and a means for positioning the hose material to be welded between the anvil and the sonotrode. In accordance with the present invention it is suggested that the anvil comprises two anvil parts which are movable relative to one another in the direction of the sonotrode, one of said anvil parts being implemented as a sealing anvil and the other part being implemented as a separating anvil. Hence, the apparatus according to the present invention permits the production of packaging units which end directly at the weld, i.e. in the case of which no length section of the foil material projects outwardly beyond the weld. The method according to the present invention is characterized in that the material of the endless hose or of the packaging unit projecting beyond the weld is cut off directly adjacent to or in said weld.
摘要翻译：本发明涉及一种用于形成由环形软管或用于密封预制包装单元的包装单元的装置和方法，包括可彼此移动的包括砧和超声波发生器的超声波焊接装置，以及用于将要焊接的软管材料定位在砧座和超声波发生器之间的装置。根据本发明，提出了砧座包括两个砧座部件，它们可以在超声焊丝的方向上相对于彼此移动，所述砧座部件中的一个被实施为密封砧座，另一部分被实施为分离砧。因此，根据本发明的设备允许生产直接在焊接处终止的包装单元，即在箔材料的长度不超过焊缝的情况下。根据本发明的方法的特征在于，环形软管或突出超过焊缝的包装单元的材料被直接切割在邻近或在所述焊缝中。
