Abstract
A roll-forming apparatus of the type used to transform a flat web or sheet of metal into a component having various cross-sectional shapes is provided with a first elongate base portion with an axis extending in a longitudinal direction, a second elongate base portion with an axis disposed generally parallel to the longitudinal direction of the axis of the first base portion, and a drive mechanism associated with the first and second base portions, the drive mechanism having a coupler associated with the first base portion, a raft plate supported by the first base portion, and a plurality of roll-forming stations supported by the raft plate. At least one of the roll-forming stations is provided with a plurality of forming rolls, a plurality of rotatable spindles for supporting the forming rolls, a first coupler adapted to be coupled to the coupler of the drive mechanism and being operatively connected to one of the spindles, and a second coupler adapted to be coupled to the coupler of the drive mechanism and being operatively connected to one of the spindles.
