The drying oven uses the stainless steel endophragm manufacture the highest temperature control is 200 centigrade. And the centigrade controlled by multistage warm, according to technological requirement accuracy control each section of drying oven temperature. The tensity completely automatic control, uses the frequency conversion velocity modulation or the digital co current velocity modulation system, and uses the multi-spot synchronization movement. Uses EPC to correct an error, guarantees the end product edge to be neat. Each transition hoop even correct grinding, polishing processing, guaranteed the material surface not scratches. The multi-purpose combined types spread the cloth to spread, the precision is high, and the performance is stable.
