2. Formation of the Pipe Once the paper is prepared, it is wrapped around a mold or core. The wrapping is done in a controlled manner to ensure uniform thickness and adhesion. Some machines employ heat and pressure to bond the layers of paper together, enhancing the integrity and strength of the pipe.
The roll forming process begins with unwinding a metal coil, which is then fed into the forming section of the machine. As the strip moves through the series of rollers, it undergoes deformation, gradually taking on the desired shape. Advanced roll forming machines may incorporate additional features, such as hydraulic systems for managing pressure and ensuring smooth operation. Once the profiling is complete, the formed strip is usually cut to length using automated shears, resulting in a finished product ready for shipment or further processing.
