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.
