Product Overview
The Pre-heater Machine is used in corrugated cardboard production lines to preheat base paper and single-face corrugated paper before the bonding process. By increasing paper temperature and helping control moisture, it provides suitable conditions for stable gluing and corrugated board forming.
The machine uses a heated cylinder with adjustable wrapping angle, allowing the preheating area to be adjusted according to different paper grades, flute types and production requirements. Single, double, triple and multi-layer configurations are available.
Key Features of the Pre-heater Machine
- The pre-heater machine, also called a preheating cylinder, complies with national pressure vessel standards and is supplied with pressure vessel and inspection certificates.
- The roller surface is precision machined, finely ground and hard chrome plated. The smooth surface reduces friction and provides wear resistance during operation.
- The wrapping angle can be adjusted electrically within 360°, allowing adjustment of the paper preheating contact area.
- Butterfly-head or flat-head cylinder designs are available to provide uniform heating of base paper.
- The machine can be configured as a single preheater, double preheater, triple preheater or multi-layer preheating system according to production requirements.
- The preheating cylinder uses a reduction motor for constant-speed rotation, helping maintain stable paper movement and reducing the risk of paper breakage.
- It is used for preheating single-face corrugated paper and liner paper in corrugated board production lines to increase paper temperature, assist bonding, control moisture and improve board forming conditions.
