This video, titled "5 ply Automatic corrugated board plant" from the Corrugated machinery company channel , shows the process of producing 5-Ply Automatic Corrugated Board, which is the core process in the production of corrugated boxes.
As the video is almost 7 minutes long and there is no transcript, the entire content is a continuous demonstration of the machinery in operation, especially focusing on the operation of the Natraj Corrugating Machinery Company plant.
Summary of the production process of 5-layer corrugated paper:
This production line is fully automated, starting from raw material (paper rolls) to finished products (corrugated paperboard cut to size).
1. Paper Feeding and Preparation
Mill Roll Stand: Several large rolls of paper (both flat and corrugated) are mounted and continuously fed into the machine. [00:10]
Pre-conditioning: The paper is heated and conditioned to prepare for corrugation and gluing.
2. Corrugation Forming and First Layer Gluing (Single Facer & Gluing)
Single Facer Unit: The flat paper (Liner) and corrugated paper (Medium) are fed into the machine to create corrugating flutes and are glued with the first layer [00:50] Produces 2-layer corrugated paper (Single Face Board)
3. Assembly into 5-ply sheets (Double Facer & 5-Ply Assembly)
Double Facer Unit (Hot Plate): The two-layer corrugated board, the middle flat paperboard, and the second two-layer corrugated board are passed through the heating platform [02:00]
Multi-layer gluing: The machine will glue the second and third layers to form a 5-layer corrugated board as specified in the name [02:40] This process requires heat and pressing to allow the glue to dry and bond completely.
4. Cutting and Stacking
Conveying: The assembled 5-ply corrugated cardboard sheets are conveyed along a long conveyor belt to await cutting. [03:30]
Slitter Scorer: The machine will cut and crease the paper according to the specified width. [04:00]
Cut-off Knife: The paper sheets are cut to the specified length with high precision. [04:40]
Automatic Stacker: The finished corrugated cardboard sheets are conveyed from the machine and automatically stacked into piles. [05:00] Ready for further production of boxes
This video demonstrates the complexity and scale of machinery used in the packaging industry, with every step being automated to ensure speed and quality in production.
