Everyone in metal fabrication is probably familiar with the rolling machine, be it of the initial-pinch, three-roll double-pinch, three-roll translating geometry, or four-roll variety. Each has its limitations and advantages, but they also share a common trait: They roll sheet and plate in the horizontal position.
A less familiar approach involves rolling in a vertical orientation. Like other methods, rolling vertically comes with its own set of limitations and advantages. The advantages almost always address at least one of two challenges. One is the effects of gravity on the workpiece during rolling, and the other involves inefficient material handling. Improving both improves workflow and, ultimately, a fabricator’s competitiveness.
Advantages of Rolling Vertically
Vertical rolling technology isn’t new. Its roots go back to a handful of custom systems built in the 1970s. By the 1990s, certain machine manufacturers were offering vertical rolling machines as regular product lines. The technology has been embraced by various industries, especially in the tank production arena.
Common tank and vessels often produced vertically include those used in the food and beverage, dairy, wine, beer, and pharmaceutical industries; API tanks for oil storage; and welded tanks for agricultural or water storage. Vertical rolling drastically reduces material handling; typically yields a higher-quality bend; and more effectively feeds the next stage of production for fit-up, alignment, and welding.
