Individual machine used in corrugator line for optimal bonding of paper web
The pre-heater is an essential part of the corrugator line, specifically designed to precondition the liners and corrugated medium. Positioned between the paper roll stand and the single facer, the pre-heater ensures that the paper achieves the correct moisture content and flexibility for optimal bonding during the corrugation process. This step is important for producing high-quality corrugated cardboard, as it prepares the paper for smooth and efficient corrugation.
