Abstract: An ultrasonic welding system and method for making welds on a strip made of polymeric material. The system includes a supporting structure, N welding equipment mounted thereon, and a processor. Each N welding equipment includes a pair of welding heads made of a sonotrode, including a sonotrode welding surface, and an anvil, including an anvil welding surface. One of the two welding heads is movable with respect to the other between a non-operating position and a welding position. A control member is operatively associated with the sonotrode and configured to vibrate the sonotrode at a nominal ultrasonic vibration frequency and to detect a current value of the vibration frequency. A vibration sensor is mounted on the movable welding head. The processor monitors the alignment condition between the sonotrode welding surface and the anvil welding surface by cooperating with the control member and with the vibration sensor.

Abstract: A production line of absorbent sanitary articles and production control method. The line includes production devices configured to perform production operations on the absorbent sanitary articles; sensors adapted to detect current values of operating parameters indicative of the current operation of the production devices; and a control unit including a memory and a processor configured to perform a comparison between the current values of the operating parameters and respective predetermined reference values stored in the memory and, in the presence of an anomalous operating parameter, to identify, among a plurality of possible malfunctioning causes, a current malfunctioning cause responsible for the anomalous operating parameter. The processor is configured to perform the comparison independently of a detection of any defects in the absorbent sanitary articles and is configured to identify the current malfunctioning cause, among a plurality of possible malfunctioning causes, starting from the anomalous operating parameter.

Abstract: An apparatus for mutually welding at least two elements of an absorbent sanitary item, including a supporting structure, a first welding member including a first welding surface, and a second welding member including a second welding surface. The second welding member is movable with respect to the first welding member between a non-operating position, in which the second welding surface is spaced apart from the first welding surface to allow at least two elements of the absorbent sanitary item to be positioned above the first welding surface, and a welding position, in which the second welding surface is in contact with the first welding surface to allow welding the at least two elements. One of the welding members includes a yielding coupling element configured to allow a relative displacement between the first and second welding surfaces as a result of the mutual contact between the second and first welding members.
