Once the yarn exits the pre-dry oven it enters the five cylinder drying section for completing the drying process. The cylinders are 800mm in diameter, steam heated (up to 5 bar steam pressure) and Teflon coated. Each cylinder is equipped with journals and 62mm bearing assemblies with steam side journals drilled and tapped for 25mm rotary joints and drive journals tapped to 19mm are included.
Steam and condensate piping is arranged so the cylinders will be individually controlled. The piping includes the steam and condensate headers, 25mm rotary joints for steam side, siphon tubes, flexible steam and condensate hose, steam traps, temperature control valves, RTD’s, main PRV and 25mm BSSV vacuum breakers.
150mm Ø Teflon coated load cell rolls are located at both the entrance and exit to the drying section. The drying section is tension controlled using an 11kW AC Vector motor. A straight comb holder is mounted at the entrance and exit of the drying section. The mechanism oscillates in a fan like motion to prevent the yarn from sticking when the machine stops and reduces wear. A static eliminator bar is located after the comb at the exit of the drying section.
