Fiber embryo tube pre-weaving PVC plastic coated lay flat hose production line adopts polyester fibers for reinforced materials. The processing technique is: firstly circular braiding machine weaves mesh embryo tubes, secondly extruder extrudes PVC soft material, thirdly PVC material coats on mesh embryo tube through the die head and finally forming to lay flat hose by water cooling. This production line uses two steps forming technique. Although it is completed by two procedures, the forming process is simple. Besides, the whole line easy to operate and maintenance conveniently, so it is deeply welcomed by users.
