Methods and apparatuses discussed herein provide for localized speed changes of an advancing substrate. Embodiments of a localized speed varying apparatus may include first and second substrate guides positioned upstream and downstream of a processing station, respectively. The substrate guides may utilize orbital motion of guide members to change the length of the substrate within the substrate guides upstream and downstream of the processing station. The changes in substrate length within the substrate guides result in localized speed changes of the substrate between the substrate guides. Coordination between the substrate guides allows for localized speed changes of the substrate passing through the processing station without affecting the speed of the substrate upstream of the first substrate guide and downstream of the second substrate guide.

The invention relates to a method and to an installation for producing a metal strip. The aim of the invention is to make sure that the metal strip formed in the casting installation passes through the first cooling and grain texturing phase substantially without being subjected to stress and without effects on the subsequent installations. To this end, the molten bath is fed to a two-roll casting device and a cast metal strip is formed in the casting gap between two casting rolls whose rotational axes lie in a horizontal plane (two-roll casting method), the thickness of the cast strip ranging between 1.0 to 20 mm, preferably between 1.5 to 12 mm. The cast metal strip that freely emerges downwards from the two-roll casting installation is directly deflected from the vertical casting direction to a substantially horizontal transport direction. The metal strip is taken up and conveyed in a controlled manner by means of a first drive roll stand that operates at a first transport speed. The metal strip is then stored for a short time in a strip accumulator, and is then taken up and conveyed by means of a second drive roll stand that operates at a second transport speed. In a final step, the metal strip is coiled up to a bundle under pretension.
