NRC Tape Making Slitting Rewinding Machine

Industrial Adhesive Tape Making Machine

This is a heavy-duty, continuous production line used in factories. The process is highly automated and can be broken down into several key stages.

Core Components of an Adhesive Tape Machine:

1. Unwinding Station: A large roll of backing material (e.g., polypropylene film, PVC, cloth, paper) is mounted here and fed into the machine.

2. Surface Treater (e.g., Corona Treater): This unit uses an electrical discharge to increase the surface energy of the backing material. This ensures the adhesive will stick to it properly.

3. Coating Head: This is where the adhesive (which can be water-based, solvent-based, hot-melt, or acrylic) is applied evenly onto the backing material. Common coating methods include knife-over-roll, slot-die, or gravure.

4. Drying Oven (for certain adhesives): A long, heated tunnel that evaporates the water or solvents from the adhesive, leaving a dry, tacky layer.

5. Laminating Station (Optional): For double-sided tape, a release liner (like silicone-coated paper) is applied here. For single-sided tape, the adhesive side might be laminated to a release film to prevent it from sticking to itself on the roll.

6. Curing/Oven Section (for certain adhesives): Some adhesives, like certain acrylics, require UV light or heat to fully cure and develop their final properties.

7. Rewinding Station: The finished tape is wound onto a large, wide "jumbo roll" (or "log roll"). This is the primary output of the tape making machine.

8. Slitting Machine (a separate but integral machine): The jumbo roll is then transferred to a slitting machine. This machine uses sharp, circular blades to cut the wide jumbo roll into multiple narrower rolls of the desired width (e.g., 1/2 inch, 1 inch, 2 inches).

9. Core Cutter & Taping: The slit rolls are then cut to the final length (e.g., 40 yards, 55 yards) and the free end is taped down. Finally, they are labeled and packaged.
