High Speed Automatic Toilet Paper Roll Converting Machine

What is a High-Speed Automatic Converting Machine?

It is a fully integrated production line that takes jumbo tissue rolls as input and produces fully packaged, retail-ready toilet paper packs as output, with the entire process controlled by a central computerized system. The goal is maximum throughput

with operational consistency.

Key Defining Features

1. Fully Integrated Line: From the unwind stand to the case-packed product, every step is automated.

2. High Production Speed: Typically ranging from 250 to 600+ rolls per minute (RPM). Some top-tier lines can exceed 800 RPM.

3. Minimal Labor: Requires only 1-2 operators for monitoring, refilling packaging materials, and addressing alerts.

4. Advanced Control Systems: Sophisticated PLC (Programmable Logic Controller) and HMI (Human-Machine Interface) panels for precise control, data logging, and diagnostics.

   The Fully Automated Workflow

   The line seamlessly integrates the following processes:

   1. Automatic Unwinding & Splicing:

      • Purpose: Holds multiple jumbo rolls.

      • Key Feature: An automatic splicer detects when a running jumbo roll is nearly finished, activates a flying splice unit, and seamlessly bonds the new roll's paper to the running web without stopping the machine. This is critical for maintaining high efficiency.

   2. Embossing & Ply Bonding:

      • High-precision embossing rollers create patterns and, for 2-ply products, glue the plies together.

   3. High-Speed Rewinding & Perforating:

      • The core of the machine. It automatically:

        • Feeds cardboard cores from a magazine.

        • Perforates the paper with extreme accuracy.

        • Winds the paper onto the cores at very high speeds, controlling tension for perfect roll hardness and diameter.

        • Ejects the finished "logs."

   4. Log Accumulation & Transfer:

      • A buffering system collects the logs and feeds them smoothly into the cutter, ensuring a continuous flow.

   5. High-Speed Log Cutting:

      • Uses ultra-precise, high-RPM circular saws to cut the logs into individual rolls without dust or paper fray.

   6. Automated Packaging:

      • This is a multi-stage process on a high-speed line:

      • Individual Wrapping: Each roll is wrapped in film or paper at high speed.

      • Multi-Packing: Wrapped rolls are automatically counted, grouped (e.g., 4, 9, 12, 24), and inserted into plastic bags or paper/plastic overwrap.

      • Case Packing: The multi-packs are automatically arranged and loaded into shipping cases, which are then sealed and palletized.
