The machine unit has adopted the techniques such as: Controlledby micro-computer, regulating the speed by Silicon DCGovernor&Frequescy Converter on the basis of absorbing theadvanced technologies of the foreign countries. The machine unithas equipped with constructions of the belt with the function ofchanging the filter automatically, drawing the flat fibers by thedrying plate of the stretching hot air oven and aggrandized theratio of L/D of the screw. There are some merits of the machineunit: The faster spped of production, more output of the flatfibers, reducing the power consumptions and good quality of theflat fibers. It can be used in the production of flat fibers byvarious of thermoplastic materials such as PP, HDPE AND LDPEetc
