An apparatus for treating a continuous moving web, comprising: a tool holder roller rotatable around a first rotation axis and carrying at least one first tool and at least one second tool spaced angularly apart from each other and having geometric characteristics different from each other, an anvil roller rotatable around a second rotation axis parallel to the first rotation axis and carrying at least one anvil element, and a control device configured to rotate the tool holder roller and the anvil roller around the respective rotation axes in at least one first operating condition and at least one second operating condition, wherein in the at least one first operating condition said at least one first tool is in phase and cooperates cyclically with the at least one anvil element and said at least one second tool is out of phase and does not cooperate with the at least one anvil element, and wherein in the at least one second operating condition said at least one second tool is in phase and cooperates cyclically with the at least one anvil element and said at least one first tool is out of phase and does not cooperate with the at least one anvil element.
