980/1020 Double Layer Roll Forming Machine
This 980/1020 double layer roll forming machine belongs to double-layer integrated cold bending equipment under roof panel roll forming machine category. The upper deck produces 1020 wide-span trapezoidal roof sheets while the lower deck forms standard 980 trapezoidal tiles. One single machine outputs two popular industrial roof profiles simultaneously, replacing two separate single-layer machines and drastically saving workshop floor space & equipment labor cost.
Both trapezoidal tile profiles fit 0.3–0.8mm color coated and hot-dip galvanized steel strips, widely applied to waterproof roof projects of steel workshops, warehouses, farm markets, agricultural greenhouses and prefab cabins.
The machine frame is integrally welded with heavy thick square tube gantry structure and stress-relieved by high-temperature annealing after welding to eliminate welding deformation stress. Dual roller decks run synchronously without vibration offset, upper and lower roller groups operate independently without mutual interference, maintaining long-term stable dimensions for both 980 and 1020 profiles. All forming rollers are precision turned solid 45# carbon steel with full hard chrome plating after surface quenching for outstanding wear and rust resistance. Separate multi-group progressive trapezoidal bending roller stands for upper & lower decks fully complete concave-convex load-bearing rib bending for two tile types in one feeding stroke, scratch-free sheet surface without spring-back cracks. Tight interlock between sheets delivers excellent roof water seepage prevention and wind uplift resistance, rib height and tooth pitch fully adjustable per custom requirements.
Equipped with two sets of independent variable frequency synchronous chain transmission, forming speed of upper and lower decks adjustable separately, running smoothly with low noise, speed steplessly switchable from 8 m/min to 22 m/min. Heavy-duty double-side manual deviation correction at feeding inlet centers steel strips to reduce edge material waste. Two independent vertical hydraulic cutting stations at the tail with thickened wear-resistant blades fit all types of color steel sheets, simultaneous cutting for two finished products, clean burr-free cut ends, fixed-length tolerance ≤±1mm. Integrated PLC touch screen control system stores two independent parameter recipes for 980 and 1020 profiles, one-click switch between single / double layer production mode, automatically completing dual-path feeding, double-deck roll forming, separate fixed-length cutting and yield counting. Only one operator can realize 24-hour non-stop alternating production of two tile types.
Every 980/1020 double layer tile roll former undergoes a 72-hour dual-layer synchronous full-load endurance test before delivery to calibrate tile wave arc, effective width and cutting tolerance for both decks. Complete double-set spare forming rollers, cutting blades, hydraulic sealing parts and bilingual machine operation & maintenance manuals are supplied as standard accessories. Xinnuo offers a 2-year full machine warranty, customized three-phase industrial voltage available for all countries, delivery lead time 50–60 days. Remote installation & debugging guidance is accessible for overseas buyers. This dual-profile all-in-one double deck roof tile forming equipment receives bulk orders from small & medium building material manufacturers worldwide.
