A Double Line Roll Forming Machine is a type of roll forming machine that can produce two different profiles simultaneously. This machine has two sets of roller tools, each with its profile running parallel. Two separate coils are fed into the machine, one on each side, and each set of rollers forms the profile of the corresponding coil.This double line roll forming machine is highly efficient and is used in industries where large production volumes are required. It is commonly used to manufacture roofing, wall panels, metal cladding, and other building materials.
