Abstract: A device for measuring the roll gap (7) between the working rollers (1a: 1b) of a cold or warm rolling stand for rolling out narrow or wide strips of metal, especially NE metal strips, by means of roll gap sensors (6) whose signals are transmitted to the servo-valves of the compressed oil control as a roll gap setpoint value for the piston cylinder units influencing said roll gap (7), and used to provide a roller gap measurement which is also suitable for such cases involving the lateral progression of said strip. In order to achieve said aim, the position or travel sensor (6) is provided in at least one bending cylinder (5a;5b) for the working cylinder (1a, 1b) for indirect reference measurement of the roll gap via the positively or negatively acting bending cylinders (5a; 5b).

Abstract: A work roll bending system for profile control of continuous metal strip during rolling which is especially useful for retrofitting an existing rolling mill absent such feature to provide it with roll bending capabilities. The advantage of the system is its compactness in the vertical direction which facilitates its positioning between housing posts of the rolling mill where space in the vertical direction is often limited. Bending wings for exerting bending forces to work roll chocks with use of hydraulic cylinder and piston assemblies extend from the chocks in an intermeshing manner to allow wings from top and bottom work roll chocks to occupy the same horizontal plane without interference during at least some roll gap settings. That bending wing arrangement also allows for elimination of a "layer" of hydraulic cylinder and piston assemblies which also reduces space requirements in the vertical direction.

Abstract: Slitting shears for sheets and strips of metal. The shears include knife rollers which support circular knives and are adjustable for adjusting the overlap of the knives. The gaps between the knives are adjustable by means of spacer sleeves arranged on the rolls between the circular knives. The slitting shears further include a bending control unit for the knife rollers for keeping constant the adjusted knife overlap and knife gaps. The bending control unit makes it possible to prevent positional changes of the cutting edges of the circular knives under load, so that cut edges without burrs can always be produced independently of the cutting forces. Bending of the knife rollers can be compensated in a controlled manner by sensing the bending of a knife roller.
