The device for rotary converting a web or sheet matter equips a processing station arranged in a machine (2) particularly producing packagings by means of cylindrical tools (10, 11). These tools are arranged in a cassette (7) and rotated by a driving device (40) equipped with a motor (42). The cassette (7), coming from an extrinsic equipment to that which normally equips the machine (2), is placed in another so-called adaptive cassette (20), which is removable and secured to the driving device (40). The latter is arranged on the adaptive cassette (20). |
