Abstract: Disclosed is a spray ramp intended to lubricate and/or cool a laminated strip and/or pressure cylinders of a mill, including: a tubular shaft of which the hollow interior volume forms a fluid admission chamber; a chassis rigidly connected to the external wall of the shaft, extending along the tubular shaft; a plurality of nozzles distributed over the length of the chassis and supported by the chassis, arranged such that the jets form a fluid curtain; and a pipe system, inside the chassis, ensuring the supply of the nozzles from the through-bores provided in the tubular wall of the hollow shaft. The pipe system includes at least one pressure levelling chamber extending over the whole active length of the chassis and through which all the fluid supplying the plurality of nozzles passes.

Abstract: A shearing device for fragmenting a metal strip includes two counter-rotating drums facing one another, a drive device connecting the drums and synchronising their rotation speed, and at least one pair of drum-supported blades. The blades engage by shearing effect during drum rotation to cut the waste. The blades of the pair have, from the cutting edge thereof, planar surfaces, referred to as overlapping surfaces, overlapping and facing one another during the shearing between blades, each blade being secured transversely to the drum, at an angle to the axis of rotation of the drum, so the plane through the overlapping surface of the blade forms an angle with the axis of rotation of the corresponding drum, producing gradual shearing. The overlapping surface of each blade is tilted so the plane passing through the overlapping surface does not intersect the rotational axis of the drum on its active width.
