(54) Apparatus and method for cutting or perforating web materials


(57) An apparatus for making partial or complete cuts and incisions on tapes made of paper, plastic material, tinfoil, or similar, comprises at least one cutter (11, 12) or any other incision tool, and a countercutter (5) or any other cooperating striking tool, at least one of them being supported rotatably, and the tape (15) made of one of the said materials being made to pass between them. According to the invention, one of the two cooperating cutting, notching and incising tools (11, 12, 5), particularly the cutter (11, 12), is alternately movable, preferably through oscillation, into an operating position and into an idle position, and is stationary during the operation of cutting, incision, or similar, executed in cooperation with the other tool, that is the countercutter (5), while the latter rotates at a speed which is markedly higher than the speed of continuous sliding of the tape (15), made of one of the said materials, between the two tools (5, 11, 12).
