Double layer roll forming machine
This double-layer roll forming machine falls under Double-layer roll forming machine subcategory of Roof Panel Roll Forming Machine series, integrated dual-deck cold bending equipment equipped with two independent upper and lower roller forming systems. It can produce two different profiles of color steel roof tiles separately or alternately, with common combinations of trapezoidal tile + corrugated wave tile, glazed tile + trapezoidal tile. One machine replaces two single-layer roll formers to greatly cut factory space occupation and equipment investment cost. It is widely suitable for small & medium building material factories and mobile on-site tile forming projects, finished sheets used for waterproof roof cladding of workshops, warehouses, rural houses and prefab cabins.
The machine frame is integrally welded with heavy section steel and treated by high-temperature stress relief annealing to eliminate welding deformation stress. Dual roller decks run synchronously without vibration deviation, with independent adjustment of rib height and effective coverage width for upper and lower roller groups to maintain precise stable dimensions for both tile 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, processing color coated & galvanized steel coils 0.3–0.8mm thick. Separate multi-group progressive bending roller stands for upper and lower decks fully form complete tile profiles in one feeding stroke, scratch-free sheet surface without bending cracks, tight interlock between sheets for excellent roof waterproof and wind resistance performance. Dual profile combinations can be customized and replaced according to clients’ construction demands.
Equipped with dual variable frequency synchronous chain transmission, forming speed of upper and lower decks can be adjusted independently, running smoothly with low noise, speed steplessly switchable from 7 m/min to 20 m/min. Dual sets of manual deviation correction mechanisms at feeding inlet center two steel strips separately to reduce edge material waste. Dual-station independent hydraulic cutting unit at the tail with two separate cutting knives performs fixed-length cutting individually, delivering clean burr-free cuts, finished length tolerance ≤±1mm. Integrated PLC touch screen control system stores two independent sets of tile profile parameter recipes for one-click production switching, 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 double-deck tile roll former undergoes a 72-hour dual-layer synchronous full-load endurance test before delivery to calibrate tile rib arc, sheet 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 provides a 2-year full machine warranty, industrial voltage customized for all countries, delivery lead time 50–60 days. Remote CNC debugging and on-site engineer installation & operation training are available for overseas buyers. This cost-effective integrated double-layer forming machine receives bulk orders from small & medium building material manufacturers worldwide.
