Influence of friction coefficient of steel-plastic composite driving on the longitudinal wrapping in the process of producing optical cable, the armored layer needs to go through the longitudinal wrapping mode, so that the steel-plastic composite belt is completely wrapped around the cable core.Generally speaking, the smaller the coefficient of dynamic friction, the less the armored layer is easy to break the belt, the higher the production efficiency, the lower the damage to the mold.Because the tensile strength of the steel-plastic composite belt is much greater than that of the aluminum-plastic composite belt, the influence of the friction coefficient of the aluminum-plastic composite on the armored longitudinal package is greater.Now THE CABLE FOR THE LADLE IS SOLD IN THE BEGINNING OF 1999, USING THE LATEST TECHNOLOGY OF OPTICAL CABLE FORMING IN the WORLD, THE NEWLY DESIGNED STEEL (ALUMINUM) BELT LONGITUDINAL PACKING device, ZB04 TYPE LONGITUDINAL PACKING DEVICE.But the difference lies in the forming device. The initial method is roller forming, which uses a set of metal guide wheels with a decreasing wheelbase to shape the steel strip.It is composed of a guide wheel, a blanking wheel, a forming wheel, a lap wheel and a sizing wheel.After that, the armour layer is finally formed by four independent die combinations.
