360S Single Facer
  • Hydraulic type, paper guiding method adopts wind suction to keep the corrugated shape stable at high speed.
  • The fan absorbs the corrugated paper in the 180 degree range of the middle corrugated roller through the vacuum box to form a negative pressure zone to complete the corrugated rolling.
  • The width of the suction groove of the lower corrugated roller does not exceed 2.5mm, which can reduce the stripe marks of single-sided corrugated cardboard.
