Double Layer Roll Forming Machine
The double layer roll forming machine can produce two different profile drawings on one machine, saving more space and more money when compared with using two different machines. The double layer panel roll forming machine can produce one layer profile at a time. There is one clutch on the side of the machine and we just need to move one handle wheel to roll form the other layer profile.
It can manufacture corrugated and trapezoid double layer, corrugated and glazed tile double layer, trapezoid and glazed tile double layer.
