Fiber winding weave PVC plastic coated lay flat hose production line adopts polyester fibers for reinforced materials. The processing technique is: firstly winding machine winds and weaves polyester fibers to mesh embryo tube to round mandrel, secondly extruder extrudes PVC soft material, thirdly PVC material coats on mesh embryo tube through the die head and round mandrel and finally forming to lay flat hose by water cooling. This production line uses one step forming process technique, although it is complicated in the replacement of hose size, this technology is simple than two-step technology: energy conservation, easy to operate and maintain, so this line is favored by customers.
