If you are sourcing an  automatic paper tube making machine  , you may wonder how industrial paper tubes and paper cores are manufactured. This article, paired with our real workshop filming, walks you through the full spiral tube winding workflow, showing how our automatic spiral paper tube making machine turns plain kraft paper rolls into sturdy, uniform cardboard tubes for packaging, textile, film, adhesive tape and paper core industries.

Paper tubes, also known as paper cores, are everywhere. They support plastic film rolls, textile fabrics, adhesive tape, label stock, and form eco-friendly packaging canisters. The most popular mass-production method is spiral winding, powered by a reliable automatic paper tube making machine. Unlike manual or semi-automatic equipment, the fully automated spiral paper tube machine integrates paper unwinding, gluing, spiral winding, forming, online cutting and finished tube output in one continuous line, greatly boosting throughput while lowering labor and material waste.

Step 1: Paper unwinding and tension control

The production starts with raw kraft paper rolls mounted on the unwinding racks of the automatic paper tube making machine. Multiple paper plies can be loaded at the same time according to the required tube wall thickness. The machine’s automatic tension control system keeps paper strips stable during feeding, avoiding slack, wrinkling or uneven tension that causes oval tubes. Operators only need to set ply quantity and paper width on the PLC touchscreen, and the machine automatically aligns paper strips for consistent feeding. This is a key advantage of modern automatic spiral paper tube making machines over old manual winding units.

Step 2: Precision automatic gluing

After unwinding, each paper strip passes through a stainless steel gluing unit. Water-based eco glue is evenly coated on the paper surface. The glue dosage is adjustable via the machine HMI. Too much glue leads to wet tubes and longer drying time; insufficient glue causes delamination and weak tube strength. Our Paper core making machine maintains stable glue application across variable production speeds, ensuring each paper ply bonds tightly. The glue tank is corrosion-resistant and easy to clean for material changeovers between different paper tube specifications.

Step 3: Core spiral tube winding forming

This is the heart of the whole spiral tube manufacturing process. The glued paper strips are fed onto a steel mandrel at a fixed spiral angle. Driven by pressure belts, paper plies wrap helically around the mandrel and overlap layer by layer, continuously building the tube wall. The mandrel size defines the inner diameter of finished paper tubes, while the number of paper plies sets wall thickness.

In real workshop footage, you can watch the continuous tube extrude forward smoothly. The spiral overlapping structure delivers higher compressive strength than parallel-wound tubes, making these tubes ideal for heavy-load industrial cores. The robust machine frame reduces vibration during high-speed running, guaranteeing roundness and consistent tube dimension batch after batch.

Step 4: Online flying cutting

The long continuous paper tube keeps moving forward without stopping production. The servo flying cutter on our automatic paper tube making machine cuts the tube to preset lengths on the fly. Servo control ensures cutting accuracy, minimal length error and clean tube ends without burrs. You can freely switch tube length settings on the touch panel to produce short packaging tubes or long textile paper cores. No manual measuring or saw cutting required.

Step 5: Drying, inspection and finished collection

Freshly cut paper tubes retain residual glue moisture. They go through air or oven drying to stabilize hardness and avoid deformation. Workers perform simple quality checks: inspect roundness, wall thickness, end face flatness and bonding quality. Qualified paper tubes are stacked and packed for shipment. The whole workflow from raw paper to finished tubes runs automatically with only one or two operators to supervise the sprial paper tube making machine.

Why choose our automatic paper tube making machine?

Many paper core manufacturers upgrade to our spiral tube winding machine to solve pain points: unstable tube quality, high labor cost, slow speed and frequent specification change downtime.
