An Automatic Stacker completes the whole production process. The traditional bomb Stacker with a motorized rollerline is best suited to Tile sheet and Light-trapez rollforming machinery. The optimum stacking system for our Heavy duty rollforming machinery is the Stacker with a sheet trolley. The trolley moves with a sheet and slides out from under the sheet after it has been cut. The sheet bundle is easy to remove from the rollerline since it is fully accessible from above.
