What’s Double Layer Machine

Double Layer Roll Forming Machine has alternating  bottom and upper stands. Rolls for one profile( like ibr sheeting ) are installed in the bottom stands, and rolls for another profile(like corrugated sheeting )are mounted on the upper stands. The whole line will use only one uncoiler, one cutoff unit, one controlled box.  But the  double layer machine can’t produce the 2 profiles at the same time. Cause the upper cut die is up for cut the upper sheets and down for the bottom sheet.

Advantage and Disadvantage

Advantage: Save plant spacer, Quick changeover, Reduce the budget.

Disadvantage: Production Capacity is half lower than 2 machines separately, a bit difficult make the adjustment because of crowed condition

Double Layer Roll Forming Machine Components

  • Q:  What possibility i can use a double layer roll forming machine?
    A:  The similar coil width, forming steps, rib height is not too big.
  • Q: How many money can save to choose a double layer machine?
    A: Actually, the machine can not save much more money, the two mill only commonly use A uncoiler, A Bed, A controlled Box, A hydraulic Station. normal design only 5000$, while production capacity is half down. and if not the plant area is limited, we don’t recommend customer buy a double layer roll forming machine

All in all, we don’t recommend the factory to buy  double layer machines to produce the trapezoidal sheets or tiles.

Believe Industry Company also customized roll forming machines, such as: Upright Rack Roll Forming Machine, Composite Floor Deck Roll Forming Machine, Roof Sheet Roll Forming Machine.
