Uses: This machine is used to make the polyester fibre and polypropylene fibre to be middle and low stretch fibre by false-twist spindles. IF equipped with compressor,it can make air-entanglement fibre. Performance: 1 Adopt the electron temperature touring control system,that the temperature control precision is high. 2 Adopt the original converter of Danfoss company to control the movement of grooved drum and I,II roller,that can meet the wide range of technological requirement. 3 Adopt double motors to drive,that make the right and left spindles having same speeds and assure every root of yarn's technology is same after they pass the false-twist spindles. 4 Adopt fully closed grooved drum boxes,not only improve its lift time ,but also decrease the noise of workshop. Main technical parameters: Spindle number: 120, 144, 168, 192, 216, 240 spindles Application range: 15-300dtex False-twisting method: Laminated disc friction type False-twisting direction: S or Z Length of cooling track: 610mm Speed: 250-520(stepless) Standard weight of coil package: 4.5kg Size of coil package: F250×250(mm) Adjusting method of draft rate: stepless speed regulation by frequency converter Warm-keep power of heat box: 3-5KW Length of upper heat box: 1400mm Length of bottom heat box: 1000mm Number of the rollers: II rollers(III roller option) Section distance: 1520/1460mm Motor power: 19.5KW Size: 3600×6690×3100mm(168 spindles)
