The ZT35-117-1000 Profile Roof Panel Roll Forming Machine is composed by the following elements:

  1. Pre-Cutter

With manual pre-cutter for easy operation and save material:The pre-cutter is

connected with PLC control system,PLC is calculating profile length within roll

forming. Once material is required to change,PLC is calculating the length for

total quantity and remind operator production finishes and able to manual

shearing material before roll forming so as to change material for new

production.It is the advanced function and good for production to save

material, no waste.
