The TC-600N Full-auto Rotary HDAF Paper Pleating Production Line is built for manufacturers seeking high-speed, stable, and precise pleating performance. With advanced pneumatic cutting, steam-assisted preheating, and an intelligent roller marking system, this production line guarantees excellent pleat consistency and durability. Its computer-controlled interface and integrated auto processes significantly reduce labor intensity and increase production output.

1. The pre-slitting uses pneumatic cutting round knife, which is adjusted simply and pressed evenly.
2. This machine equips the preheating and water steam device, to prevent the paper breaking when roller marking.
3. This machine equips the gear collecting system, so to faster the pleating speed and well pleated the paper.
4. The rolls can be made with bubbled type or the pleat-lock type, which is used to maintenance the certain distance between two pleats.
5. This high automatic machine has the process of the process of the auto-couning, pleating, preheating and forming.
6. This machine is computer control and simple operation.
High Automation – integrates slitting, pre-heating, steam softening, pleating, and forming in one continuous line.
Stable Pleat Quality – roller marking system ensures uniform and straight pleats.
Low Paper Breakage – steam and pre-heating greatly improve paper toughness before folding.
Customizable Roller Types – bubbled or pleat-lock rollers for different HDAF structures.
User-Friendly Operation – PLC computer control with simple adjustment and stable performance.
Efficient Production Speed – up to 35 m/min supporting large-scale production.
