Slitting Capacity at 99% slitter uptime: a worked example in nonwoven materials & technical textiles

What does the result look like when slitter uptime reaches 99%? The full calculation is worked below with real intermediate numbers. Use it when slitting capacity in nonwoven materials and technical textiles is being asked to take on more work and you need to know if there is room.

The inputs for this scenario

  • Slit rolls produced per slitter cycle: 4 units / cycle (unchanged)
  • Available slitter cycles in window: 480 cycles (unchanged)
  • Slitter uptime (running time fraction): 99 % (raised for this scenario; the documented default is 90)
  • First-pass yield off the slitter: 97 % (unchanged)

Working through the calculation

  • Applying the documented formula (Gross slitting capacity = slitting capacity output per cycle × available slitting capacity cycles) to the inputs above produces each figure below.
  • At this operating point the engine returns 1,844 units for good slitting capacity, the number this scenario is built around.
  • At this operating point the engine returns 1,920 units for gross slitting capacity.
  • At this operating point the engine returns 19.2 units for slitting capacity downtime loss.
  • At this operating point the engine returns 57.02 units for slitting capacity yield loss.

How this compares with the baseline

  • Against the tool's baseline example, where slitter uptime sits at 90% and the headline result is 1,676 units, this scenario comes in 10% above the baseline at 1,844 units.
  • A figure at this level is achievable when slitter uptime is genuinely sustained, not just peaked for a shift. It uses flat-average uptime and yield, so it will overstate output when losses are lumpy — a long unplanned stop or a bad parent roll that scraps a whole set won't be modeled accurately.

Results at a glance

  • Good slitting capacity: 1,844 units (headline result)
  • Gross slitting capacity: 1,920 units
  • Slitting capacity downtime loss: 19.2 units
  • Slitting capacity yield loss: 57.02 units
