The system has a separating wall, for separating the processing zone from the activation zone; at least a movement actuating element, which develops from the activation zone to the processing zone, crossing the separating wall and that has a longitudinal developing axis; movement actuating means, arranged in the activation zone, for moving the movement actuating element at least along a first direction transverse to the respective axis. ## Claims ### Claim 1 A sealing and guiding system (1) for a packaging machine (M) comprising a processing zone (S), for receiving products to be processed, and an activation zone (N), that are adjacent each other; the system (1) comprises: a separating wall (2), for separating the processing zone (S) from the activation zone (N); at least one movement actuating element (3), that develops from the activation zone (N) to the processing zone (S), crossing the separating wall (2) and has a longitudinal developing axis (H); movement actuating means (4), that are arranged in the activation zone (N), for moving the movement actuating element (3) at least along a first direction (D1), transverse to the respective axis (H); wherein, with the system (1), the movement actuating element (3) is not subjected to axial translations; wherein the separating wall (2) comprises: a first part (20) comprising at least a first housing circular seat delimited by a first circular edge; at least a first disk (21), which is inserted in the first circular seat so as to be rotatable with respect to the first part (20) and is coplanar with the first part (20); the first disk (21) comprises in turn at least a second circular seat delimited by a second circular edge, that is eccentric with respect to the center (O) of the first disk (21); and at least a second disk (22), which is inserted in the second circular seat so as to be rotatable with respect to the first disk (21) and is coplanar with the first disk (21); the second disk (22) comprises, in turn, a third circular seat delimited by a third circular edge, that is eccentric with respect to the center (P) of the second disk (22); wherein movement actuating element (3) is inserted in the third circular seat so as to be rotatable with respect to the second disk (22); and wherein the system (1) comprises rotary sealing means (200, 210, 220), arranged at the first circular seat, at the second circular seat and at the third circular seat, allowing the sealing between the processing zone (S) and the activation zone (N) and the relative rotation of the first disk (21), of the second disk (22) and of the movement actuating element (3). ### Claim 2 (depends on 1) The system according to claim 1, wherein the movement actuating means (4) are arranged for directly acting on the movement actuating element (3) for moving it along the first direction (D1), with the first disk (21) and the second disk (22) which rotate due to the movement of the movement actuating element (3). ### Claim 3 (depends on 2) The system (1) according to claim 2, wherein the movement actuating means (4) comprise a motor (40) and a rod-crank system (41, 42), connected to the movement actuating element (3). ### Claim 4 (depends on 1) The system (1) according to claim 1, wherein the movement actuating means (4) are arranged to act on the first disk (21) and on the second disk (22) for indirectly moving the movement actuating element (3) along the first direction (D1). ### Claim 5 (depends on 4) The system (1) according to claim 4, wherein the movement actuating means (4) comprise a first motor (421) and a second motor (422), arranged for directly moving the first disk (21) and the second disk (22), respectively; the first motor (421) and the second motor (422) comprising respective cogged ends (E1, E2); and the first disk (21) and the second disk (22) comprising respective cogged edges (B1, B2) arranged at the activation zone (N), suitable to mesh with the cogged end (El) of the first motor (421) and with the cogged end (E2) of the second motor (422), respectively. ### Claim 6 (depends on 1) The system (1) according to claim 1, further comprising guiding means (5), arranged at the activation zone (N), connected to the movement actuating element (3) for guiding the movement actuating element (3) at least along said first direction (D1) transverse to the respective axis (H). ### Claim 7 (depends on 6) The system (1) according to claim 6, wherein the guiding means (5) and the movement actuating means (4) are arranged for guiding and moving the movement actuating element (3) also along a second direction, transverse to the respective axis (H) and different from the first direction (D1). ### Claim 8 (depends on 1) The system (1) according to claim 1, wherein the movement actuating element (3) is shaped so as to define on the inside thereof a chamber (31), that communicates with the activation zone (N). ### Claim 9 (depends on 8) The system (1) according to claim 8, wherein the movement actuating element (3) carries operating means at a respective portion (30) that is arranged in the processing zone (S), for operating in the processing zone (S); the system (1) further comprising control means, arranged within the chamber (31) of the movement actuating element (3), for controlling the operating means independently of the movement of the element (3). ### Claim 10 (depends on 8) The system (1) according to claim 8, wherein the chamber (31) of the movement actuating element (3) forms a passage for conveying processing liquids or gases, or electrical connections, into the processing zone (S). ### Claim 11 (depends on 1) A packaging machine (M), comprising: a processing zone (S), in which products to be packaged are conveyed; an activation zone (N), arranged adjacent to the processing zone (S); and a sealing and guiding system (1) according to claim 1.
