Pultrusion & Continuous Composite Profiles worked example

Take-Up Capacity at 99% puller and take-up uptime: a worked example

This scenario runs the take-up capacity calculation on the strong side: 99% puller and take-up uptime, with every other input held at its documented default. Use it when take-up capacity in pultrusion and continuous composite profiles is being asked to take on more work and you need to know if there is room.

The inputs for this scenario

  • Profiles handled per puller cycle: 4 units / cycle (unchanged)
  • Available puller cycles in the period: 480 cycles (unchanged)
  • Puller and take-up uptime: 99 % (raised for this scenario; the documented default is 90)
  • Post-pull yield: 97 % (unchanged)

Working through the calculation

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

How this compares with the baseline

  • Against the tool's baseline example, where puller and take-up uptime sits at 90% and the headline result is 1,676 units, this scenario comes in 10% above the baseline at 1,844 units.
  • Use it when the puller sets your line speed and you need a realistic committable throughput for the pulling section. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Good output capacity: 1,844 units (headline result)
  • Gross capacity: 1,920 units
  • Uptime loss: 19.2 units
  • Yield loss: 57.02 units
