Abstract: A roll-forming apparatus is provided with a plurality of roll-forming stations adapted to facilitate the formation of either a C-shaped component or a Z-shaped component from a sheet of material. The roll-forming stations have forming rolls that make contact with the sheet of material and a pair of telescoping arbor assemblies that support the forming rolls so that the lateral distance between the forming rolls may be adjusted. The roll-forming apparatus has a number of movable forming rolls and a number of fixed forming rolls having two different forming surfaces to facilitate the formation of both C-shaped and Z-shaped components.

Abstract: A roll-forming machine is provided with a base structure, a plurality of first roll-forming stations that form a first component having a Z-shaped cross section, and a plurality of second roll-forming stations that form a second component having a C-shaped cross section. At least one of the roll-forming stations has a pair of rotatable arbors adapted to support a plurality of forming rolls and a pair of support structures adapted to support a plurality of bearing assemblies. The roll-forming station also includes a pair of adjustment mechanisms that allow the position of some of the bearing assemblies to be adjusted and a pair of compression assemblies that exert a force upon some of the bearing assemblies when the bearing assemblies are moved away from an initial position.

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.

Abstract: A roll former line for forming different shapes including a first roll stand attached to a bed which provides vertical adjustable movement. The roll stand includes three spindles in vertical alignment with each other, the forming rolls on the top and bottom spindles working against opposite sides of the middle forming roll, so as to provide reverse shapes between the top and middle forming roll and the middle and bottom forming roll. Linear actuators are connected to the bed of the first roll stand for moving the first roll stand vertically on the bed. Opposite the first roll stand on the line is a second roll stand attached to a second bed including two spindles in vertical alignment and corresponding forming rolls thereon. The first roll stand can be raised or lowered by the linear actuators so as to use reverse forming rolls on the first roll stand in conjunction with the forming rolls on the second roll stand to form a reverse shape on one edge of the sheet being formed.

Abstract: A raft assembly in the roll forming art having a plurality of forming roll stands including a combined horizontal raft plate and first vertical stand formed together in an L-shaped single cast. The first vertical stand supports multiple station pairs of spindles at one end thereof and a plurality of second vertical stands each of which supports the opposite ends of a said pair of spindles on a single roll stand and bolts for attaching the second vertical stands to the raft plate oppositely positioned from said first vertical stand.
