The unwinder is the first stage of the impregnation line and is designed to handle large rolls of paper efficiently. It ensures smooth and continuous unwinding of paper into the process line, maintaining consistent web tension and minimizing downtime. Depending on the production setup, the unwinder can be configured with manual or automatic splicing features for uninterrupted operation.
Key Features:
Suitable for paper widths up to 2200 mm
Roll diameter handling capacity: 1200 mm
Maximum roll weight: 2000 kg
Automatic/Manual splicing system
Web tension control with Pneumatic system
Operator-friendly loading and unloading design
Impregnation Unit
The impregnation unit is the heart of the production line, where the base paper is impregnated with phenolic, melamine, or other specialty resins. It ensures uniform penetration and impregnation of resins across the paper surface, maintaining quality and consistency.
Key Features:
Suitable for resin type: Phenolic / Melamine / Custom
Temperature controlled impregnation bath with adjustable resin level
Stainless steel construction for corrosion resistance
Quick cleaning and changeover system
Drying Zone
The drying zone is responsible for evaporating solvents or water content from the impregnated paper. It ensures controlled drying while preventing blistering, resin migration, or paper deformation.
Key Features:
Drying Zone length: 3750 mm each
Temperature range: 80-200 °C
Heating medium: Direct Gas / Thermic Oil / Steam
Air circulation system with adjustable flow
Gravure Coating Unit
The gravure coating unit provides a precise and consistent application of resins, additives, or decorative layers onto the base paper. The gravure cylinder ensures accurate coating weight control and surface finish.
Key Features:
Adjustable coating weight: 20-35 g/m²
Doctor blade with adjustable pressure
Compatible with various resin viscosities
Air Cooling Unit
The web aligner ensures that the paper runs straight and centered throughout the line, reducing wastage and preventing misalignment in downstream processes.
Web Aligner
The web aligner ensures that the paper runs straight and centered throughout the line, reducing wastage and preventing misalignment in downstream processes.
Key Features:
Automatic web guiding system
Sensor-controlled edge detection
Correction accuracy: ± 1 mm
Low-maintenance design
Water Cooling Unit
The water cooling unit provides an additional cooling step, stabilizing paper dimensions and improving handling before cutting or stacking.
Key Features:

Corrosion-resistant construction
Rewinder
The Rewinder is used to neatly roll up the treated and dried paper at the end of the impregnation line. It ensures proper winding with controlled tension, allowing easy handling, storage, or transfer to the next stage of production. A reliable rewinder minimizes waste, prevents wrinkles or telescoping, and guarantees consistent roll quality.
Key Features:
Smooth and precise winding of resin-treated paper
Tension control for uniform roll formation
Handles various roll diameters and core sizes
Quick and easy roll changeover
Operator-friendly design for reduced downtime
Rotary Cutter
The rotary cutter cuts the continuous paper web into sheets of desired length with precision. It ensures accurate cutting speed synchronization with the running web.
Key Features:
Cutting length range: 2000 mm – 4500 mm
Accuracy: ± 2 mm
Servo-driven cutting system
Easy blade replacement
Pallet Changing System
The pallet changing system automates the stacking and palletizing of cut sheets, reducing manual handling and improving productivity.
Key Features:
Some of the main characteristics:
Maximum stack height: 400 mm
Smooth pallet changeover without production stoppage
Panel Board
The panel board houses all the electrical, automation, and control systems of the production line. It integrates PLC, HMI, drives, and safety systems for seamless operation.
Key Features:
PLC and HMI system
Variable frequency drives for motors
Touchscreen interface
Real-time monitoring of temperature, tension, and speed
