The support element (4,5,8) allows the tube (1) to slide along a predetermined direction (A) parallel to its axis longitudinal (x) and to rotate about the same axis, and the carriage (7) is adapted to move bidirectionally the blade (6) parallel to the longitudinal axis (x) of the tube (1). The support element (4,5,8) has, where the cutting unit (CU) is arranged, apart (5) movable from and towards the blade (6) to maintain the tube (1) spaced from the latter and, respectively, for approaching the tube to the same blade (6) during a cutting phase. ## Claims ### Claim 1 A machine for cutting cardboard tubes, the machine comprising: a cutting unit comprising a carriage on which is mounted a blade and a support element for supporting a cardboard tube to be transversely cut by the blade, wherein said support element allows the tube to slide along a predetermined direction parallel to a longitudinal axis of the tube and to rotate about the longitudinal axis, wherein said carriage is adapted to move bidirectionally such that the blade moves parallel to the longitudinal axis of the tube, said support element having a part where said cutting unit is arranged, said part being movable from and towards the blade to maintain the tube spaced from the blade and, respectively, for approaching the tube to the blade during a cutting phase. ### Claim 2 (depends on 1) A machine according to claim 1, wherein said support element comprises a fixed part upstream of the cutting unit, a movable part in an area of intervention of the blade, and a fixed part downstream of the cutting unit. ### Claim 3 (depends on 1) A machine according to claim 1, wherein said predetermined direction is horizontal. ### Claim 4 (depends on 1) A machine according to claim 1, wherein said support element has a concave cross section, with a concavity facing upwards. ### Claim 5 (depends on 4) A machine according to claim 4, wherein said support element has a V-shaped cross section. ### Claim 6 (depends on 1) A machine according to claim 1, wherein the cutting unit is placed downstream of a tube forming machine which produces the tube, said support element extending between the tube forming machine and the cutting unit and downstream of the cutting unit ends with a conveyor that moves away cuts formed by the cutting of the tube. ### Claim 7 (depends on 1) A machine according to claim 1, wherein said part of the support element is constrained to said carriage. ### Claim 8 (depends on 1) A machine according to claim 1, wherein said part of the support is independent from said carriage. ### Claim 9 (depends on 1) A machine according to claim 1, wherein said blade is vertically oriented. ### Claim 10 (depends on 1) A machine according to claim 1, wherein said blade is adapted to remove material from the tube. ### Claim 11 (depends on 2) A machine according to claim 2, wherein said predetermined direction is horizontal.
