A paper production line is a complex, integrated system of machinery that transforms raw fibrous materials—typically wood pulp, recycled paper, or agricultural residues—into continuous rolls of finished paper. Modern lines can produce everything from lightweight tissue (14–22 gsm) to heavy kraft linerboard (200–400 gsm), operating at speeds exceeding 2,000 meters per minute on advanced tissue machines.
At YOCO Group, we design and manufacture complete paper production lines that balance throughput, energy efficiency, and product quality. Whether you're setting up a greenfield mill or upgrading an existing operation, understanding each stage of the production chain is essential for making informed equipment decisions.
Stock preparation is where papermaking truly begins. This stage converts raw pulp—whether virgin fiber bales, recycled paper, or integrated pulp mill output—into a consistent, clean fiber suspension suitable for the paper machine. Key equipment includes:
The approach flow system delivers a stable, homogeneous fiber suspension to the headbox. This system includes machine chests, fan pumps, basis weight valves, and pressure screens. Consistency at this stage is typically 0.5–1.2%—meaning each liter of water carries only 5–12 grams of fiber. The approach system must eliminate pressure pulsations and air entrainment, both of which cause basis weight variations in the finished sheet.
Advanced approach systems from YOCO Group incorporate dilution water control that adjusts cross-machine consistency profile in real time. This technology reduces basis weight variation (2-sigma) to below 1.0%, compared to 2–3% on older machines.
The forming section is where the fiber suspension transitions from a liquid slurry to a wet web. Four predominant former configurations exist:
Dryness after the forming section ranges from 18–24%, depending on vacuum box configuration and wire design.
The press section removes water mechanically—far more cost-effective than thermal drying. Each 1% increase in sheet dryness entering the dryer section reduces steam consumption by approximately 4%. Modern press sections feature:
The dryer section evaporates the remaining water—roughly 50–60% of the web mass—using steam-heated cylinders arranged in tiers. A typical fine paper machine has 40–80 dryer cylinders, each 1.5–1.8 meters in diameter. Key design considerations:
After drying, the sheet passes through calenders that modify surface properties:
The finished sheet is wound onto a reel spool at the dry end. Modern reel sections feature:
After reeling, jumbo rolls transfer to winders where they are slit into customer-specified widths and wound onto cores. Two-drum winders remain the industry standard, with advanced programmable tension control (TNT—tension, nip, torque) ensuring uniform roll hardness across the set.
YOCO Group supplies turnkey paper production lines ranging from 30–200 TPD capacity, covering tissue, kraft, fluting, testliner, and fine paper grades. Every line is engineered to customer specifications with options including:

Request a QuoteA typical turnkey paper production line installation takes 12–18 months from contract signing to commercial production. Equipment manufacturing accounts for 6–8 months, site preparation 2–3 months, and installation/commissioning 4–6 months. YOCO Group provides detailed project timelines and milestone tracking throughout the delivery process.
Small-to-medium lines from YOCO Group range from 30 to 200 tons per day (TPD). A 100 TPD tissue line, for example, can produce approximately 30,000–35,000 tons annually at 92% operating efficiency, sufficient for a regional market serving 5–15 million consumers.
While some machines are designed for a single grade (e.g., dedicated tissue machines), multi-grade machines can produce fluting, testliner, and kraft papers within a basis weight range of 70–200 gsm. Grade changes typically require 15–45 minutes of transition time. YOCO Group engineers can advise on machine configuration for multi-grade flexibility.
For an integrated paper production line (stock prep through winding), specific energy consumption typically ranges from 400–650 kWh per ton of paper for tissue grades, and 350–500 kWh/ton for packaging grades. Thermal energy adds 1.5–2.5 GJ/ton. YOCO Group designs feature variable frequency drives and heat recovery systems that can reduce total energy costs by 15–20% compared to older installations.
Yes. Every YOCO Group production line includes a comprehensive training program: 2–4 weeks of classroom instruction, 4–8 weeks of hands-on operator training during commissioning, and ongoing remote support via video conferencing. We also offer annual maintenance audits and spare parts management programs to maximize your line's lifespan.
