MACHINE FOR ADJUSTABLE LONGITUDINAL CORRUGATING OF SHEET MATERIALS

摘要

: A machine for adjustable longitudinal corrugating of sheet materials, particularly of metal with stepwise folding/bending over free running rollers and countec-rollers, so that alternating longitudinal convex and concave corrugations are formed. At each profiling step there are upward and downward forming rollers (47) which can be individually adjusted laterally to the direction of corrugation. Separate from the forming rollers there are at least one set of drive rollers (60) and counter-rollers (37) where both the drive rollers and the counter-rollers can be adjusted laterally to the direction of corrugation.
