The two lower rollers adopt the non-polar pressureregulating uniform roll. The uniform roll line pressure can beobtained by adjusting the oil pressure in the cavity. Theelastic roll sleeve on the non-polar pressure regulatinguniform roll can better compensate the roll deformation.The fabric passes through two rolling zones at the same timeto obtain the effect of ordinary rolling three to four times.High calendering efficiency and remarkable calenderingeffect on fabric breathability, lint resistance and thinthickness.lt is widely used in field fabric clothing, outdoorsports clothing,safety protection clothing,non-wovenfabrics such as calendering processing.etc.
