Abstract: A shape metering process and related apparatus for continuously detecting and measuring the profile and flatness of a rolled metal strip or a non-metallic strip coming off mill rolls, and for making continuous corrections, in real time, of the errors from which faults and unevenness in the strip tend to originate. A single source of fluid power registers differences in pressure which are localized in relative zones which are ranged transversely to the path of the strip movement and across its width. Such differences in pressure are proportional to the differences in tension with which the strip is invested. These differences can be detected, measured and displayed so as to analogically represent the shape of the strip. The same pressure can also be a continuous and direct-acting control medium for an actuation of a conventional media utilized in correcting the thermal condition of the mill rolls.

Abstract: The balancing-vessel transducer disclosed consists of a structure or housing enclosing two intercommunicating chambers part-filled with a liquid, and made freely rotatable about a horizontal axis coinciding substantially with its center of mass. One such chamber is in receipt of a pneumatic signal, while the remaining chamber is held at a constant reference pressure, such that liquid is displaced from one chamber to the other, thereby occasioning a redistribution of mass; the structure responds by rotating, its movement being checked by a force of reaction that varies in proportion to the force of the pneumatic signal, and turns through an angular distance that can be sensed in the shift of an eccentric pin attached to the structure itself.

Abstract: A roller flanging apparatus for flanging a metal strip has a flanging head that comprises a pair of working idler rollers. The idler rollers have outer surfaces forming a flanging angle therebetween. The edge of the metal strip passes between the rollers in contact with the roller outer surfaces to provide a flange on the metal strip edge. The idler rollers have an axis which defines an acute angle with a line extending perpendicular to a line that indicates the direction of movement of the metal strip and the acute angle is defined in the direction of movement of the metal strip.

Abstract: In a metal strip rolling mill having a strip shape measuring means connected to adjust the mill to control the strip shape, improved strip shape control performance is achieved by mounting a hold-down roll between the measuring means and the take-up reel.
