Double layer roof panel roll forming machine brief .
The double layer roof panel roll forming machine is is actually build up by two sets of single layer roof panel roll forming machines sharing the machine base and roll tooling,two sets of material feeding devices. It is based on the same design as single layer roof panel roll former.
The double layer roof panel roll forming process :
The double layer roof panel roll forming line is starts from the unwinding of metal coils , entry the main roll forming equipment(up layer or bottom layer，not available at the same time) after pinching rollers, then roll formed to specific profile according to client’s design , cut to length by hydraulic power cutter (can go up and down with two directions )and then stack& packing.
Decoiling—guiding&leveling—roll forming—hydraulic shear—stacker
The standard profile drawing for double layer roof panel roll forming machine.
Layout of double layer roof panel roll forming line.
The standard whole solution on the double layer roof panel roll forming line is combined of uncoiler , main roll former(twos sets)stationary post-cut hydraulic shear, run out table .
