1. A labelling machine for labelling a stack of elements for placing a label located between elements, the labelling machine comprising:
a support structure;
a printing means configured for printing a label to be placed on a stack of elements;
a head supported on the support structure, the head being provided with the printing means, the head being movable and adjustable at least in height through guiding means and motorised means; and
a separation means intended for separating two elements superimposed on one another forming part of the stack, such that they vertically separate an element to be handled, generating a free space between the two elements intended for the arrangement of the label,
wherein abutment means are provided located in the head intended for making contact with a stack of elements to be handled and preventing the movement of the stack of elements during the placement of the printed label, the abutment means located in the head comprising a pneumatic cylinder located in an inclined plane with respect to a horizontal plane, the pneumatic cylinder being coupled to an abutting platen provided with a surface oriented in a vertical plane and intended for abutting with the stack of sheets, and wherein the separation means comprise at least one retractable blade, such that it is movable from a first retracted position to a second extended position in which said at least one blade is introduced into the stack of elements.
