SUMMARY The machine comprises a heated ironing roller (2), supported, guided and rotated on a frame (1), a parallel pressing roller (3) in contact with the ironing roller (2) and endless bands (4) mounted on satellite rollers and embracing part of the ironing roller (2). Axial journals (3a) of the pressing roller (3) are supported against inclined planes (5) fixed to frame (1) and at an angle with respect to a plane tangential to the ironing roller (2) and the pressing roller (3) on the line of mutual contact. The journals (3a) rest on the planes (5) with a force that includes a normal component derived from the weight of the pressing roller (3), resulting in an ironing force that is greater than the weight of the pressing roller (3) due to a wedge effect favoured by the opposite directions of rotation of the ironing roller (2) and the pressing roller (3).

Said floating group comprises: a drum (20) aligned with a centre line (M) which rotates within a wrapping bin (10) driven by a motor (32), and when it rotates it creates, by an effect of masses unbalance, an actual rotation axis (N) different from said centre line (M); a counterweigh (40) of mass m CE associated to a front part of the bin (10) and a counterweigh (42) of mass m CT associated to a front part of the drum (20), where the ratio [ m CT /( m CE +m CT )]x100≥55, said mass m CT either a given magnitude centred with said centre line (M) or a very lower magnitude and in the form of one or more fluid rings (60), the stresses the floating group sustains resulting substantially reduced, it being for it made in a light construction.
