4400 mm White Test Paper Manufacturing Machine
This test paper machine is a 4400mm double-wire multi-cylinder paper machine specifically engineered for producing test liner paper and white test paper with consistent quality and excellent strength. The test paper machine uses three air-cushion headboxes with dilution water control to ensure excellent fiber distribution. The test paper machine features a triple-wire forming section with a 24.5-meter bottom wire, 7-meter top wire, and 12-meter middle wire, plus full-ceramic dewatering elements for superior sheet formation. The test paper machine’s press section uses a four-roll three-nip design with large-diameter rolls to achieve high sheet dryness. The test paper machine has a dryer section with 37 drying cylinders and 6 VAC cylinders arranged in groups for efficient drying. The test paper machine also includes a sizing machine, calendering machine, and reel drum-type reeling machine with automatic roll change.
