Abstract: A leveling machine with parallel cylinders comprising at least one pair of active leveling cylinders (2), placed on each side of the strip to be leveled and each free to rotate and supported on a crosspiece (5) through a series of spaced bearing members (3). Each bearing member (3) comprises a bearing part (31) mounted in an individual frame forming a casing, connected to crosspiece (5) with a possibility of a clearance transverse to the plane of motion P of strip (A). Each of the said casings bears individually on crosspiece (5) through a positioning member (6) of variable length, for individual adjustment at the level of the corresponding bearing part (31) with respect to the crosspiece (5). The invention is particularly applicable to leveling of thin metal strips.

Abstract: An air knife device for regulating the thickness of a layer deposited on a strip at the output of a bath, comprising at least one nozzle defined by two lips spaced a small distance apart, the nozzle being supplied with pressurized fluid in order to blow at least one flat jet of fluid onto the strip. The device is associated with at least one fluid cushion stabilizer arranged on at least one side of the nozzle along one of its lips and comprising a substantially flat wall extending from this lip in a direction substantially parallel to the strip so as to define a thin, flat space between the wall and the strip. A fluid is introduced into this space for the formation of a fluid cushion which is able to stabilize the vibrations of the strip.
