The module contains a member (1) provided with a guideway (8) in a mating guideway (18) on the frame (10) of a filling tube (14). A locking element (11) secures the member (1) and the frame (10) in a fixed position relative to each other. The member (1) is provided with an element (2) for linear motion of a sliding carriage (3) and an adjustable stop (6) for restricting the carriage movement (3). The ultrasonic transducer assembly (4) is firmly affixed to the carriage (3), whereas the anvil (7) is affixed to the member (1). The frame (10) may contain an adjustable stop (9) for locking the member (1) in a defined position as the member is inserted into the mating guideway (18).
