Raise the bar on safety, while improving threading efficiency

Safety days_millSmaller.png

While threading safety has always been a concern for papermakers, demand for improved safety has never been stronger. This increased interest in worker welfare, coupled with the steady rise in production goals, has forced facilities to face the seemingly impossible task of implementing safety measures that won’t crater the efficiency of the machine. They need to eliminate manual interventions, without incurring more downtime in the process.

New solutions from ANDRITZ make it possible to raise the bar on safety while simultaneously improving threading efficiency. These custom solutions automate manual processes and fix existing threading systems that no longer function as designed.

This is one of those rare scenarios where enhanced safety measures will generate a measurable ROI. The use of automated processes, that are properly tuned, create a safer production environment, where people remain outside machine boundaries. The ability to rethread efficiently at production speed, allows for a quicker recovery after sheet breaks. Threading repeatability is also improved because a successful rethread no longer relies on operator skill.

Incorporating automated threading processes on a paper machine with ANDRITZ

In many cases, press-to-dryer threading can occur in a tight application where there is an extreme offset to the ropes. These conditions can be problematic to the process and the safety of operators because it requires hand threading often at reduced speeds.

Working with ANDRITZ, threading can be automated, improving the safety and efficiency of the operation. Here’s the process:
  • The ANDRITZ team completes a process audit with on-machine trials (when necessary)
  • They propose an appropriate, engineered solution
  • The equipment is installed and optimized
  • Performance tracking and preventative maintenance plans are implemented
Results of process automation:
  • Threading at production speed
  • Repeatable performance
  • Safer process

Process automation creates a safer work environment for operators, increases machine uptime and improves process reliability. ANDRITZ’s extensive experience and expertise in paper threading meets the market demand for improved safety while delivering an impressive ROI, a quality that is unique in a safety-focused solution.
