The Ultimate Guide to Tissue Machine: Types, Functions, and Maintenance
In the world of paper production, the tissue machine stands as a cornerstone of efficiency and innovation. Whether you’re a manufacturer, engineer, or industry enthusiast, understanding these machines is essential for optimizing operations and ensuring product quality.
Types of Tissue Machines
Tissue machines come in various configurations to meet diverse production needs. The most common types include crescent former machines, suction breast roll machines, and twin-wire formers. Crescent formers are widely used for their versatility in producing facial tissues, napkins, and toilet paper. Suction breast roll machines excel in high-speed operations, while twin-wire formers offer superior sheet formation for premium products.
Key Components and Operational Workflow
A typical tissue machine consists of a headbox, forming section, press part, Yankee dryer, and reel. The headbox distributes the pulp slurry evenly onto the wire, where water drains to form a paper web. The press section removes additional moisture, and the Yankee dryer—a large, steam-heated cylinder—dries the sheet while imparting a soft, creped texture. Finally, the reel winds the finished tissue into large rolls for converting.
Functions and Applications
Tissue machines are engineered to transform pulp into soft, absorbent, and durable tissue products. Key functions include fiber alignment, dewatering, pressing, and creping. These processes determine critical properties like tensile strength, bulk, and absorbency. From household toilet paper to industrial wipes, tissue machines support a broad range of applications, emphasizing hygiene and comfort.
Maintenance Best Practices
Regular maintenance is crucial for minimizing downtime and extending machine lifespan. Implement routine inspections of the Yankee dryer surface, doctor blades, and felt condition. Lubricate moving parts, monitor vibration levels, and schedule predictive maintenance using IoT sensors. Addressing wear early prevents costly breakdowns and maintains consistent product quality.
Frequently Asked Questions
What is the production capacity of a standard tissue machine?
Modern machines can produce 50–200 tons per day, depending on design and raw materials.
How does creping affect tissue softness?
Creping on the Yankee dryer creates micro-folds, enhancing softness and bulk without compromising strength.
What are common challenges in tissue production?
Issues like sheet breaks, uneven moisture, and dryer coating buildup require proactive monitoring and skilled troubleshooting.
