Transversal cutting machine comprises feeding means (20) that supply a log of paper (15), for example hygienic paper, to a sawing station at which rolls or stacks (16) are cut off from the log (15) by a blade (25). During the cutting step the log (15) is held by a clamping device (1), divided in two parts (2, 3) arranged respectively upstream from and downstream of a slit (17) through which the blade (25) passes. In particular, the first part (2) and the second part (3) of clamping device (1) are movable relatively so that during the cut the log (15) is locally subject to traction at the same time of the blade (25) driven in the log. This way, during the cutting action of the blade (25) an opening (17) is created on the log (15) having a size at least the same as the thickness of blade (25) same. This makes easier the action of blade (25) since it reduces the friction produced between the blade (25) and the log (15). Moreover, the clamping device reduces the friction between the blade and the log thus reducing the wear caused by the cutting step.
Transversal cutting machine of a log of paper having a longitudinal axis, said log being conveyed towards a cutting zone where a part thereof is blocked by a clamping device so that a blade is driven in the paper cutting in turn the log into rolls or packs, said clamping device comprising a first and a second part respectively upstream from and downstream of said blade, characterised in that said clamping device moves during the cut so that said blade driven in the log encounters a minimum resistance.
