    An apparatus and a method for practicing perforations in a moving material in the form of a band. An apparatus for practicing perforations in a moving material in the form of a strip, comprising at least one rotating tool, driven by a rotating shaft, provided with a series of punches radially distributed and capable of moving relative to the rotary tool between an operative extracted position and a non-operative retracted position, and vice versa, the apparatus comprising a driving means capable of transmitting a turning movement at variable speeds to the axis of rotation, and therefore to the rotary tool; and a cam mechanism that drives the movement of the punches between their operative and non-operative positions and which is preferably also mounted rotatable about an axis concentric to the axis of rotation of the rotating tool.

    The operation of the apparatus 1 is explained by referring to Figs. 1 to 5, showing the apparatus 1 according to a transverse cutting plane coinciding with the beam of guide stems 10 of the rotating tool 3.
    5 Referring to Fig. 1, the cross-sectional view allows a better display of the positioning device 7. In the example, this positioning device 7 comprises two band diverters 7a and 7b that force the material 2 in the form of a desired band drill to rest on the deflection roller 18. The band-shaped material 2 can slide continuously, by rotating said deflection roller 18 which rotates freely around the axis
    10 4 ’. The means that drag or allow the advance of the material are not illustrated in this Fig. 1. In the example, these drag means, which include a swingarm to keep the band to be perforated taut, are external and are not part of the apparatus 1.
    The sequence of Figs. 1 to 5 shows an operation cycle of cam mechanism 6, which
    15 will be completed between every two consecutive drilling operations, that is, between a drilling operation and the next one.
    Starting from the situation illustrated in Fig. 1, which shows the apparatus 1 an instant after performing a drilling operation on the material 2, the driving means
    20 associated with the axis of rotation 4 rotate this clockwise and according to an angular speed wu that may be different from the angular speed wr of the deflection roller 18 on which it supports, without skating, the material 2 to be drilled. At the same time, the drive means print the cam mechanism 6 also clockwise around the axis 4 ’at an angular speed wl, the relationship wl> wu being fulfilled.
    25 Once the relative position has been reached between the rotating tool 3 and the cam mechanism 6 shown in Fig. 2, a turning movement in the opposite direction to that of the rotating tool 3 is printed to said cam mechanism.
    30 Note that between the situations in Figs. 1 and 2, the angular position of the section 15 of the cam groove 14 does not coincide with the angular position of the punch 5 which will perform the following drilling operation.
    The opposite direction of the cam mechanism 6 and the rotating tool 3 will continue until
