Abstract: A device for scaling cut-out cardboard blanks (2, 2?) includes the high-speed (1.4V) ejection element (I) of a cutting machine and low-speed (V?) receiving element. The device is characterized in that it is provided with an intermediate adjusting module (II) whose at least blank-driving speed is adjustable and which is arranged between the ejection element (I) and the receiving element (III).

Abstract: An apparatus for shaping a flexible web (2) includes, between an entry roller (5) and a forming roller (3), a regulating module (7) provided with a starting roller (13) designed to control the movement and the speed of the web upstream of the shaping roller (3) and at least one mobile guide element (9) designed to exert, at least on one buffer loop (8) of the web (2) formed between the rollers (5, 3), a positive guiding thereof, in accordance with a law of displacement which is a function of the length of the buffer loop (8) in operation.

Abstract: A device for fixing a printing sleeve (3), in particular a printing form or a blanket drum, to a drive cylindrical shaft (1) on which a deformable cover (2) is arranged between the printing sleeve (3) and the shaft (1). The surface of the shaft (1) is grooved by a series of cavities (7) separated by bearing surfaces (12) which the cover (2) is rested on. The device also comprises an element for providing with the radial deformation of the deformable areas of the cover (2) by overpressure produced on the external face thereof or under-pressure on the internal face thereof. The device is characterized in that the shaft (1) and the printing sleeve (3) are provided with angular indexing elements (25).

Abstract: The invention concerns a device for positioning a plate (3) on a roll (1), in particular a chopper or folding roll. Said device is characterized in that the roll is provided with magnetic fixing means maintaining the plate on the surface thereof, and two centring elements whereof at least one (9) is mobile and longitudinally spaced apart from the first, so as to cooperate with matching means maintaining the plate (3), the mobile centering element (9) being linked to control means (15) for displacing it along the transverse axis of the roll (1).

Abstract: A machine is described for handling die-cut carton blanks as they emerge from the die-cutter. The die cut web is separated into sheets of blanks and projected sequentially onto a conveyor. The conveyor is operated at a speed which is less than that at which the sheets are projected onto the conveyor so that the distance between the sequential die cut is closed up, the sheets being maintained in contact with the conveyor by air pressure.
