What is a Spiral Tube Making Machine?

It is an industrial machine that produces cylindrical tubes and cores by continuously winding multiple layers of paper or paperboard strips onto a rotating mandrel at a precise spiral angle. This method creates tubes with exceptional strength, rigidity, and crush resistance, making them

ideal for a vast range of industrial and consumer applications.

How It Works: The Spiral Winding Process

1. Unwinding: Large rolls of paper (parent rolls) are mounted on unwind stands. Machines often have multiple stands to allow for different

   paper grades and multi-layer construction.

2. Gluing: Each paper strip passes through a precision gluing system that applies a controlled amount of adhesive (e.g., PVA, hot melt) to one

   side.

3. Spiral Winding: The heart of the machine. The glued paper is guided onto a stationary mandrel (which sets the tube's inner diameter) by a "winding head." As the mandrel rotates, the paper is wound at a fixed spiral angle (typically 15-85°).

4. Forming & Pressure: The newly formed tube passes under pressure rollers or belts. This ensures tight bonding, eliminates air bubbles, and creates a smooth, consistent wall thickness.

5. Cutting: Once the tube reaches a pre-set length, a high-speed cutter (rotary or flying saw) slices it without stopping production.

6. Ejection & Drying: The cut tube is ejected and may travel through a drying oven to cure the adhesive quickly.

Key Components of the Machine

• Unwind Stands: Hold the large paper rolls.

• Mandrel: The central shaft that determines the tube's internal diameter.

• Gluing System: Tanks, pumps, and applicators for precise adhesive control.

• Winding Head/Bridge: Guides the paper at the precise spiral angle.

• Pressure Rollers/Belts: Apply heat and pressure to consolidate the tube layers.

• Cutting System: High-speed cutter for accurate length separation.

• Control Panel (PLC): The computerized brain for setting all parameters.

• Drying System (optional): Ovens or infrared dryers to accelerate curing.

Common Applications of Spiral Tubes

The tubes produced by these machines are essential in countless industries:

• Packaging Cores: For plastic films, foil, labels, and adhesive tapes.

• Construction: Concrete pouring forms (sonotubes/column forms).

• Paper & Hygiene: Cores for toilet paper, paper towels, and kraft paper.

• Textiles: Yarn cones and fabric rolls.

• Shipping & Storage: Protective mailing tubes for posters and documents.

• Specialty Products: Firework casings, electrical insulation, and promotional materials.
