Double-layer roll forming machine
This double layer roll forming machine belongs to double-layer integrated cold bending equipment under roof panel roll forming machine category. It integrates two independent upper & lower roller forming systems, capable of producing two different profiles of metal roof tiles separately or alternately. The most popular combinations are trapezoidal load-bearing tile + corrugated wave tile, antique glazed tile + trapezoidal tile. One machine replaces two single-layer tile roll formers, greatly saving workshop space and equipment investment cost.
Finished metal sheets are widely used for waterproof roof cladding of steel workshops, warehouses, rural houses, prefab cabins and wall fencing, compatible with 0.3–0.8mm color coated & hot-dip galvanized steel strips.
The machine frame is integrally welded with heavy 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 allow independent adjustment of rib height and effective coverage width to keep precise stable dimensions for both tile profiles. All forming rollers are precision turned solid 45# carbon steel with full hard chrome plating after quenching for superior wear and rust resistance. Separate multi-pass progressive bending roller stands for upper and lower decks fully complete tile bending profiles in one feeding stroke, scratch-free sheet surface without spring-back deformation. Tight interlock between tiles delivers excellent waterproof and wind resistance performance, double profile combinations can be customized by replacing roller sets per clients’ drawings.
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 units at the tail with two separate cutting knives perform fixed-length cutting individually, delivering clean burr-free cuts, finished length tolerance ≤±1mm. Integrated PLC touch screen control system stores two independent tile parameter recipes for one-click production switch, 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-layer 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, customized three-phase industrial voltage available for all countries, delivery lead time 50–60 days. Overseas buyers can enjoy remote CNC debugging and on-site engineer installation & operation training. This cost-effective all-in-one double-layer forming machine receives bulk orders from small & medium building material manufacturers worldwide.
