Roll Forming Process
Step 3: Produce a Bend Progression, or “Flower” Pattern
With the strip width calculated, you can now create a bend progression, often called a “flower” pattern. This pattern visually represents each stage of the bending process, showing how the flat strip of material will be gradually shaped into the desired cross-section. The flower pattern is essential for planning the roll tooling and ensuring a smooth, consistent forming process.
Step 4: Layout and Design the Roll Tooling Around the Flower
After finalizing the flower pattern, it’s time to layout and design the roll tooling. This involves creating detailed drawings of the rolls themselves, specifying the shape, size, and positioning of each roll to match the stages of the flower pattern. Precision is key here, as the rolls must work together in perfect harmony to form the material correctly without causing defects or unnecessary stress.
Step 5: Incorporate Tooling Accessories
The final step in roll form tooling design is incorporating any necessary accessories. These may include side rolls, edge guides, or special cutting or punching tools integrated into the roll forming line. These accessories are essential for achieving the
