Abstract (en)

[origin: US4627258A] An apparatus for shaping a strip, especially a metal strip includes a pair of working rolls which are provided with a plurality of forming tools spaced about the circumference of the rolls. Arranged before the working rolls is a pair of guide rolls which run in synchronism with the strip speed. In order to be able to increase the operating speed of the apparatus, i.e. to allow the working rolls to run at a higher speed than the advance speed of the strip, in between the guide rolls and the working rolls a roller is located which is movable in a direction perpendicular to the advance motion of the strip and is supported by the strip itself and by springs located in respective casing. A compensation between the different speeds of the guide rolls and the working rolls is provided by the gradual depression of the roller by the strip against the force of the spring.
