The braking device comprises at least one flexible braking means (1) extending across the trajectory of the sheets (2) and mounted so as to pivot around a transverse axis (4) so that its trajectory around the said axis intersects the trajectory of the sheets (2), the direction of rotation of the end of the said flexible braking means (1) and intersecting the trajectory of the sheets (2) being opposite the direction of motion of the sheets, and also comprises drive means for pivoting the braking means (1) in dependence on the longitudinal dimensions of the sheets (2) and the frequency with which they pass. The means driving the braking means (1) around the said transverse axis (4) comprise a variable-speed electromagnetic actuator (5) connected to control means which in real time record the parameters relating to the longitudinal dimension of the sheets and the frequency with which they pass.
A braking device in a reception station of a machine for processing articles in sheet form, the device comprising at least one braking means (1) extending across the trajectory of the sheets (2) and adapted to be moved between at least two limit positions, one in which its trajectory meets that of the sheets (2) and the other in which the braking means is away from the trajectory of the sheets, and also comprising drive means for moving the braking means between the said limit positions in dependence on the longitudinal dimension of the sheets (2) and the frequency with which they pass, characterised in that the means driving the braking means (1) comprise a variable-speed electromechanical actuator (5) connected to control means (8, 9) which in real time record the parameters relating to the said longitudinal dimensions of the sheets and the frequency at which they pass.
A device according to any of the preceding claims, characterised in that the said control means are programmed to permit modification of the operating parameters of the braking means.
