Abstract: A method of continuously straightening metal strip comprises directing the strip over devices which act on the strip to effect its straightening by first causing a stretching and leveling and thereafter stretching and bending. The device for continuously straightening the thin metal strip comprises a plurality of entrance rollers arranged in succession at an entrance portion and a plurality of delivery rollers arranged in succession at a delivery portion with a stretching and bending device arranged between the two portions. The metal strip is guided over the entrance and delivery rollers as the rollers are driven by a drive motor and a common device member driven by the motor. At least two of the entrance rollers and at least two of the delivery rollers are tensioning rollers. A differential is included in the drive of each tensioning roller and it includes an overdriving motor with an adjustable speed.

Abstract: The method and apparatus provide for transversely separating and laterally trimming or finishing continuously passing strips in processing lines for strip material, such as metallic strip. The strip is first severed in transverse direction and immediately thereafter is trimmed at the sides thereof. The time required for adjusting the lateral shears is approximately equal to that of the coil exchange operation leading to the time gained, and stoppages of strip in the operating stages are precluded.
