1. A machine for stabilising palletised loads, comprising:
a functional arrangement,
a first movement apparatus adapted to generate a relative motion of revolution of the functional arrangement around the palletised load according to a predetermined revolution axis (Z),
a second movement apparatus adapted to generate a relative motion of translation of the functional arrangement with respect to the palletised load in a direction parallel to the revolution axis (Z),
wherein the functional arrangement comprises at least:
a support shaft having a predetermined central axis (A) and adapted to coaxially receive a reel of a covering tape,
a motorised drive roller having a rotation axis (b) parallel to the central axis (A) of the support shaft,
a contrast roller having a rotation axis (C) parallel to the rotation axis (B) of the drive roller, and
actuator members adapted to create a relative movement of said drive roller and said contrast roller in transversal direction with respect to the respective rotation axes (B, C) from a distanced configuration towards a neared configuration and vice versa from the neared configuration towards the distanced configuration,
wherein in the distanced configuration, between the drive roller and the contrast roller, a gap is defined, adapted to be crossed with clearance by the covering tape unwinding from the reel,
wherein in the neared configuration, the drive roller and the contrast roller are adapted to clamp said covering tape,
wherein the support shaft and at least one of the contrast roller and the drive roller are mounted cantilevered on a structural part of the functional arrangement, so that each one of them comprises a first axial end, which is coupled to the structural part of the functional arrangement, and a second opposite axial end, which is a free end, and all of them extend from the respective first axial end to the respective second axial end in the same direction,
wherein the functional arrangement comprises a cutting device for separating the covering tape from the reel, the drive roller and the contrast roller being operatively interposed between the support shaft and said cutting device,
wherein the cutting device comprises at least:
a blade,
a blocking device operatively positioned between the blade and the support shaft, to selectively block the covering tape (800) unwinding from the reel, and
actuator members adapted to move said blade transversely with respect to the covering tape, and
wherein said blocking device comprises a pair of plates and actuator members adapted to create a relative movement of said plates between a distanced configuration, in which the covering tape passes with clearance between said plates, and a neared configuration, in which the covering tape is tightened between said plates.
