This section explains development of the banding header as a friction-binding technology. In general, band used for the plastic banding makes out of the polyester with other additives, thus becomes an intensified basic material and bound with heat. Weight of the plastic band is only 1.37 times greater than that of water (i.e., 1.37g/cm³). Shock Reserve and Elongation are superior, thus does not leave the band mark on the surface of the cold rolling due to the weight while being transported. However, since the tensile strength over the binding area is low, the binding area is broken while being transported. Therefore, we increase its intensity concentrated on the binding area.Table 1 shows characteristics of the steel band, general plastic band, and PET band. Considered that intensity of the steel band on the welding area is below 450N/mm², if its intensity of PET band on the binding area is over 80%, it is noted that mechanical properties are good enough to replace the steel band for the coil wrapping. In addition, because the elastic elongation is 8 times superior to the steel band, it reduces the number of the band mark damages occurred while being transported. Figure 3 is picture of PET Banding Header being assembled as a final device.
