a driven counter-roller (4) provided with at least one abutting counter-profile (5); kinematic means (6) for directly transmitting motion, in a synchronised fashion, between the roller (2) and the counter-roller (4), the kinematic means being connected to respective shafts (2a, 4a); adjustable pusher elements (7), adapted to allow an incision or cutting contact between the roller (2) and the counter-roller (4); at least one rolling element (10, 11) interposed between the roller (2) and the counter-roller (4), and adapted to separate the rotation of the motor-driven roller (2) from the rotation of the thrust rings of the driven counter-roller (4). ## Claims ### Claim 1 A roller-type compression-incision-cutting unit (1) for packaging material comprising: a motor-driven roller (2) defining a first axis (X2) and provided with at least one projecting compression-incision-cutting profile (3); said roller (2) being adapted to rotate about said first axis (X2); a driven counter-roller (4) defining a second axis (X4) parallel with the first axis (X2), said counter-roller (4) being provided with at least one abutting counter-profile (5) and being adapted to rotate about said second axis (X4); kinematic means (6) for directly transmitting motion, in a synchronised fashion, between the motor-driven roller (2) and the counter-roller (4), the kinematic means (6) being connected to a first shaft (2a) supporting the roller (2) and to a second shaft (4a) supporting the counter-roller (4); thrust elements (20) connected to the counter-roller (4) adapted to make contact with bearing elements (21) connected to the roller (2); pusher elements (7) for pushing the thrust elements (20) into contact with the bearing elements (21); said unit (1) being characterised in that it also comprises at least one rolling element (10, 11), interposed between said roller (2) and said counter-roller (4), being adapted to allow the rotation of the counter-roller (4) to be driven only by the direct transmission kinematic means (6). ### Claim 2 (depends on 1) The unit according to claim 1, wherein said at least one rolling element (10, 11) is arranged on said second shaft (4a) of said counter-roller (4). ### Claim 3 (depends on 1) The unit according to claim 1 , wherein said thrust elements (20) comprise at least one thrust ring (8, 9) coupled to said at least one rolling element (10,11). ### Claim 4 (depends on 3) The unit according to claim 3, wherein each of said at least one thrust rings (8, 9) is interposed between and rotatably in contact with an external part (10a, 11a) of said at least one rolling element (10, 11) and said bearing elements (21), in such a way as to freely rotate with respect to said counter-roller (4), said counter-roller (4) being driven by said roller (2) by means of the kinematic means (6). ### Claim 5 (depends on 3) The unit according to claim 3, wherein said at least one rolling element (10, 11), at its internal part (10b, 11b), is coupled to said second shaft (4a) of the counter-roller (4); the internal part (10b, 11b) of the rolling element (10, 11) being integral with the counter-roller (4). ### Claim 6 (depends on 1) The unit according to claim 1, wherein said at least one rolling element comprises a rolling bearing (10, 11) interposed between said roller (2) and said counter-roller (4), in such a way that, at the thrust elements (20) and the bearing elements (21), the roller (2) does not transmit a rotational torque to the counter-roller (4). ### Claim 7 (depends on 1) The unit according to claim 1, wherein each of said at least one thrust rings (8, 9) is made of metal. ### Claim 8 (depends on 1) The unit according to claim 1, comprising two rolling elements, each comprising a rolling bearing (10, 11), said two rolling elements being arranged at respective ends of the counter-roller (4). ### Claim 9 (depends on 3) The unit according to claim 3, comprising at least two thrust rings (8, 9) mounted on respective rolling bearings (10, 11) arranged at respective ends of the counter-roller (4) and in tangential contact with at least two bearing elements (21) of the roller (2). ### Claim 10 (depends on 1) The unit according to claim 1, wherein said packaging material consists of filter paper webs containing infusion products.
