PRE-HEATER – STABLE HEATING SOLUTION FOR CORRUGATED PAPER PRODUCTION
The Pre-Heater is a critical component in the corrugated cardboard production line, responsible for controlling moisture and preheating liner and medium paper before they enter the single facer or double facer. Proper temperature and wrap angle control ensure optimal paper conditions for adhesive bonding, flute stability, and flatness of the finished board.
PTS offers a full range of pre-heaters, including:
- PH: Basic model
- PC: Integrated with control cabinet and automatic wrap angle adjustment
- PH-T: Overhead design for liner paper, ideal for reducing heat loss before entering the single facer
…suitable for both semi-automatic and fully automated corrugating lines.

Key Technical Features:
- Double guiding rollers:
Effectively increase the wrap angle of the paper, enhancing heat transfer and improving tension control – especially for lightweight or high-speed paper applications. - Automatic wrap angle adjustment:
Integrated with the production management or PLC control system, the wrap angle is automatically adjusted based on the running speed and paper type. This prevents over-heating, protects paper integrity, and ensures adhesive activation at the ideal temperature. - Tension and balance roller:
Installed at the paper exit side of the pre-heater to eliminate transverse tension issues, ensuring the paper feeds into the next section evenly and without wrinkles. - Overhead bridge pre-heater design (PH-T):
Applied for liner paper where heat retention is crucial. The heated paper enters the single facer immediately, minimizing heat loss and improving bonding efficiency. - High-precision chrome-plated heating rolls:
Ensure uniform heat distribution, corrosion resistance, and long service life – especially important for continuous high-speed operation.
