Double Layer Roll Forming Machine

Introduction of Double Layer Roll Forming Machine

To meet the requirements for roll forming two different profiles in a limited plant area with quick product changeover, Believe Industry(BELi®) have various kinds of double layer roll forming machine.

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
