ABSTRACT:
A roll-forming apparatus of the type used to form components, such as purlins, having C-shaped and/or Z-shaped cross-sections from sheets of planar material is provided with a plurality of roll-forming stations adapted to form first and second components each of which has a C-shaped cross section with a center portion and a pair of legs connected to the center portion, where the legs of the first component have a first length and the legs of the second component have a second length different than the first length. The roll-forming stations include a first roll-forming station having a plurality of forming rolls and a second roll-forming station for forming the legs of the first and second components. The second roll-forming station has a first pair of forming rolls, a second pair of forming rolls, and a mechanism for supporting the pairs of forming rolls and for adjusting the position of the pairs of forming rolls from a first position in which the second pair of forming rolls make contact with a portion of the first component to a second position in which the second pair of forming rolls make contact with a portion of the second component.
