Cardboard Paper Tube Making Machine In Africa

1.What is a Spiral Paper Tube Making Machine?

It is an industrial machine that manufactures paper tubes and cores by winding multiple layers of paper (kraft, recycled, specialty papers) in a spiral pattern around a rotating mandrel, using adhesive to bond the layers. This method creates strong, durable, and dimensionally stable cylindrical products.

2.Key Advantages of the Spiral Winding Process:

• High Strength: The cross-grain spiral structure provides excellent crush resistance and torsional strength.

• Flexibility in Dimensions: Can produce very long tubes (cut to any length) and a wide range of diameters from a few mm to over 500 mm.

• Material Flexibility: Can use various paper grades, laminated papers, or composite materials (e.g., paper with foil or plastic layers).

• Seamless Structure: The spiral overlap creates a consistent wall thickness without a straight seam vulnerability.

3.How It Works: The Production Process?

1. Unwinding: Multiple rolls of paper (slitting rolls) are mounted on a creel stand. The number of plies determines the tube wall thickness.

2. Gluing: Each paper web passes through a precision gluing unit, applying a controlled amount of adhesive (PVA, hot melt, etc.) to one side.

3. Spiral Winding: The glued paper strips are fed onto a rotating, fixed-diameter mandrel. The angle of the feed determines the winding angle (typically 15-30°). The paper wraps around the mandrel, bonding layer upon layer.

4. Forming & Drying: The wound tube travels along the length of the mandrel. Heaters (IR or hot air) or air drying partially cures the adhesive to set the shape.

5. Cutting: A traveling rotary saw or cut-off system cuts the continuous tube into pre-set lengths.

6. Ejection & Stacking: Finished tubes are ejected, automatically stacked, and bundled for shipment.

4.Types of Machines

• Semi-Automatic Machines: Require more manual intervention for loading paper, changing mandrels, and removing finished tubes. Suitable for lower-volume or multi-diameter production.

• Fully Automatic Machines: High-speed, computer-controlled systems with automatic roll splicing, CNC cutting, and robotic handling. Designed for large-scale, single-diameter production.

• Specialized Machines: Designed for specific products like edgeboard (paper protection for pallets), latex spiral tubes (for concrete columns), or composite tubes (paper + other materials).

5.Common Applications of Spiral Paper Tubes

• Industrial Cores: For winding textiles, films, foil, laminates, paper, and adhesive tapes.

• Packaging: Heavy-duty mailing tubes, poster tubes, packaging for carpets, and protective edgeboard.

• Construction: Sonotubes® for concrete columns, forms for piers.

• Specialty Products: Cores for capacitors, electrical insulation tubes, fireworks tubes, and furniture legs.

6. FAQs for Automatic Paper Tube Making Machine

Q1: What types of paper tubes can an automatic paper tube making machine produce?

A1: This automatic equipment manufactures spiral‑wound paper cores and paper tubes for multiple industries. Output includes packaging paper cores, tape core tubes, textile winding tubes, film and foil cores, as well as kraft cardboard industrial paper tubes. It supports production for both thin‑wall light‑duty tubes and heavy‑duty high‑strength paper cores according to production settings.

Q2: What raw paper materials are compatible with the automatic paper tube making machine?

A2: It works with kraft paper, corrugated laminated paper, composite paper strips and recycled paper. Operators can use different paper grammages to adjust final tube strength. Multiple‑layer paper feeding design allows stacking different paper stocks to reinforce tube wall for heavy‑load application scenarios.

Q3: How accurate is the tube size on an automatic paper tube making machine?

A3: Driven by servo motor and precise cutting unit, inner diameter, wall thickness and cutting length are controllable. Length tolerance stays within ±0.5 mm. The finished tubes keep good roundness without deformation. All dimension parameters can be quickly modified on the PLC touch‑screen for fast order switching.

Q4: How much labor and workshop space does an automatic paper tube making machine require?

A4: Fully‑automatic models greatly cut manual work. Only 1‑2 operators per shift are needed for material feeding and finished‑tube collection. Standard unit requires around 80‑120 m² workshop area. Customers can select single‑head or multi‑head configurations based on target daily output volume.

Q5: What technical and after‑sales support do overseas clients receive from NRC Machinery?

A5: Every automatic paper tube making machine includes factory warranty, English operation manuals and maintenance video tutorials. Lifelong remote technical support and online troubleshooting are provided. On‑site installation and staff training are available as optional services.
