NRC150 Paper Tube Rolling Machine For Sale

Understanding the Machine: Core Concepts

The Paper Tube Rolling Machine is an industrial system that transforms rolls of paper or paperboard into sturdy, cylindrical tubes and cores.

The fundamental process involves winding multiple layers of paper around a central mandrel, using adhesive between the layers to create a

strong, monolithic structure.

There are two primary winding technologies, and choosing the right one is critical:

1. Spiral Winding Machines

• How it Works: Paper strips are fed at a precise angle onto a rotating mandrel, creating a continuous spiral seam.

• Characteristics:

  • Excellent Flexibility and Crush Resistance: The spiral structure distributes stress evenly.

  • Can Produce Very Long Tubes: Limited mostly by handling logistics.

  • Slightly Slower than parallel winding for high-volume, short tubes.

• Ideal For: Mailing tubes, concrete sonotubes, fabric rolls, cores for films and foils (where flexibility is key).

2. Parallel Winding Machines (Convolute Winding)

• How it Works: Paper is fed straight onto a stationary mandrel, with the layers wound parallel to each other.

• Characteristics:

  • High Rigidity and Compressive Strength: Ideal for supporting heavy rolls.

  • Very High Speed for producing shorter tubes.

  • Clean, Straight Edges: Perfect for end-user-facing products.

• Ideal For: Cores for paper towels, toilet tissue, adhesive tapes, composite cans (like Pringles), and high-strength industrial cores.
