Start-Stop vs. Non-Stop:
A Strategic ROI Analysis

In the competitive landscape of tissue converting, the choice between Start-Stop and Non-Stop rewinder technology is a critical financial decision. For plant managers, the Return on Investment (ROI) is determined by balancing initial CAPEX with long-term operational efficiency and daily metric output.

1. Production Throughput: Eliminating Downtime

The primary driver of ROI in industrial rewinding is the reduction of non-productive time.

Start-Stop Tech

While highly flexible, these machines must decelerate for every core change. Even high-speed models like our TB-FJC400 face a 15-20% output gap compared to continuous systems due to these cycles.

Non-Stop Tech

Utilizing a continuous turret system (as seen in the TB-JRT500 ), this technology ensures zero-downtime transitions by maintaining constant speed during core exchanges.

Key ROI Insight

By eliminating stop-start cycles, continuous factories can reclaim up to 2 hours of pure production time per shift.

2. Operational Costs & Efficiency

Beyond speed, sustainability and waste reduction are key drivers in modern engineering cost analysis.

Constant Web Tension

Non-stop machines maintain a steady tension profile, reducing material waste by an average of 3-5% compared to start-stop cycles where tension fluctuations are frequently unavoidable.

Power Consumption

Accelerating massive rollers from zero to 500 m/min creates electrical spikes. Continuous motion reduces mechanical fatigue on Siemens servo drives and lowers peak energy demand significantly.

3. The Decision Matrix: Scaling Your Factory

  • Mid-Scale Efficiency (<15 Tons/Day): The Start-Stop series offers a faster "break-even" point for growing manufacturers requiring high SKU flexibility and lower initial capital.
  • Industrial High-Volume (>25 Tons/Day): For 24/7 operations, the Titan Series is the benchmark. The higher initial investment is offset by the massive increase in logs per year and reduced cost-per-unit.

Conclusion: Data-Driven Manufacturing

Choosing the right rewinding technology requires an integrated view of your factory's output goals and financial strategy. At Tongbang Intelligent Equipment, we build both technologies to the highest industrial standards, ensuring that whether you prioritize flexibility or pure volume, your investment is protected by world-class engineering.
