Machines and Options

The unwinder forms the starting point of the impregnation line and is engineered for reliable handling of large paper rolls. It provides controlled and continuous feeding of the paper web into the production line while maintaining stable web tension for consistent processing. To suit different production requirements, the system can be equipped with either manual or automatic splicing arrangements, helping reduce interruptions and improve overall line efficiency.

The impregnation unit is a critical section of the production line, responsible for thoroughly saturating the base paper with phenolic, melamine, or specially formulated resins. The system is engineered to achieve consistent resin distribution and controlled penetration throughout the paper, ensuring uniform quality, reliable processing, and repeatable production results.

The drying zone is a vital part of the impregnation process, designed to remove moisture and volatile components from the resin-treated paper under controlled conditions. It provides uniform and efficient drying while maintaining the dimensional stability and surface quality of the paper. Precise temperature and airflow management help minimize issues such as blistering, resin migration, and deformation during processing.

The gravure coating unit is designed to deliver a controlled and uniform application of resin, additives, or decorative coatings onto the paper surface. Using a precision gravure cylinder and doctor blade arrangement, the system maintains consistent coating weight and surface quality across the full web width. Its flexible configuration allows it to handle different coating formulations and viscosity levels according to production requirements.

The Air Cooling Unit is engineered to efficiently bring down the temperature of the impregnated paper web after the drying process. Positioned at the outlet of the drying section and, where applicable, before the Gravure Coating Unit, it uses controlled ambient or forced air circulation to achieve uniform cooling across the web width. This controlled temperature reduction helps prepare the paper for subsequent processing while minimizing the risk of curling, sticking, or dimensional distortion.

The Web Aligner is designed to maintain accurate and stable positioning of the paper web throughout the impregnation line. By continuously monitoring the web position and making precise lateral corrections, it keeps the material properly centered and minimizes tracking errors. This helps reduce edge wastage and ensures smooth, reliable feeding into subsequent processing stages.

The Water Cooling Unit is designed to provide controlled and efficient cooling of the impregnated paper after the heating and coating stages. By reducing the web temperature in a controlled manner, it helps maintain dimensional stability and prepares the material for subsequent operations such as cutting, stacking, or further processing. The closed-loop design ensures reliable cooling performance with minimal water consumption.

The Rewinder is the final stage of the impregnation line, designed to collect the processed paper into clean and uniform rolls. It provides controlled winding tension and accurate roll formation, ensuring that the finished material can be safely handled, stored, or transferred to subsequent production processes. The system is engineered to minimize common winding issues such as wrinkles, loose edges, and telescoping while maintaining consistent roll quality.

The Rotary Cutter is designed to convert the continuous impregnated paper web into accurately sized sheets at high production speeds. The cutting mechanism is synchronized with the web movement to deliver clean, consistent cuts while maintaining the required sheet length and dimensional accuracy. Its servo-controlled operation provides precise cutting performance and smooth adjustment for different production requirements.

The Pallet Changing System is designed to automate the collection and stacking of cut paper sheets, ensuring neat and organized pallet formation with minimal operator intervention. The system enables efficient pallet exchange while maintaining continuous production, helping reduce manual handling, improve workplace efficiency, and increase overall line productivity.

The Panel Board serves as the central control and automation hub of the impregnation line, bringing together the electrical, drive, instrumentation, and safety systems in one integrated platform. It enables operators to monitor and control key production parameters while ensuring synchronized operation of the complete line. The user-friendly interface provides real-time process information and supports efficient troubleshooting and system management.
